What Exercise Burns the Most Calories in One Hour: Unlocking Your Calorie-Torching Potential

The Ultimate Guide to Maximizing Calorie Burn Through Exercise

I remember vividly the first time I tried to get serious about losing weight. The internet was a bewildering maze of conflicting advice, but one question loomed large: "What exercise burns the most calories in one hour?" It felt like the holy grail of fitness, the one answer that would magically melt away the pounds. I’d spend hours on the treadmill, convinced that the sheer duration was the key, only to find my progress plateauing. It was frustrating, to say the least. This quest for the most efficient calorie-burning exercise is a common one, driven by a desire to see tangible results without dedicating an entire day to working out. But the reality, I’ve learned, is far more nuanced and, dare I say, more empowering than a single magic bullet.

Understanding the Calorie Burn Equation

Before we dive into specific exercises, it's crucial to understand what influences how many calories you burn in an hour. It’s not just about the activity itself; several personal factors play a significant role. Think of it as a complex equation where various elements contribute to the final sum.

Body Weight: This is perhaps the most significant factor. A heavier individual will inherently burn more calories performing the same exercise as a lighter person because they have more mass to move. It takes more energy to propel a larger body through space.
Intensity: How hard are you working? This is paramount. A leisurely jog will burn far fewer calories than a high-intensity interval training (HIIT) session, even if the duration is the same. Your heart rate is a good indicator of intensity; the higher your heart rate, the more calories you're typically burning.
Muscle Mass: More muscle mass means a higher resting metabolic rate. Muscle tissue is metabolically active, meaning it burns calories even when you're not exercising. So, while building muscle takes effort, it pays dividends in your overall calorie expenditure throughout the day.
Age: As we age, our metabolism tends to slow down. This means older individuals might need to work a bit harder or longer to achieve the same calorie burn as younger counterparts.
Sex: Generally, men tend to have more muscle mass and a higher metabolic rate than women, which can lead to a higher calorie burn.
Fitness Level: A highly conditioned athlete will be more efficient at performing an exercise, meaning they might burn slightly fewer calories than a beginner doing the same activity at the same perceived exertion level because their body has adapted to the demands.
Environmental Factors: Exercising in extreme temperatures (hot or cold) can increase calorie expenditure as your body works harder to regulate its internal temperature.

So, when we talk about "what exercise burns the most calories," we're really asking what exercise, performed by an average individual at a certain intensity, yields the highest caloric output. It's a useful generalization, but always remember that your personal results may vary.

The Top Calorie-Burning Exercises: Beyond the Treadmill

Now, let's get to the heart of the matter. When we talk about maximizing calorie burn in a single hour, we're often looking for activities that engage large muscle groups, demand significant cardiovascular effort, and can be sustained at a high intensity. While the treadmill can be a workhorse, some activities truly take the crown.

1. High-Intensity Interval Training (HIIT)

It's almost impossible to discuss maximizing calorie burn without mentioning HIIT. This training method involves short bursts of intense anaerobic exercise followed by brief recovery periods. The beauty of HIIT is its efficiency; you can achieve a significant calorie burn in a much shorter timeframe than traditional steady-state cardio. But what makes it so effective for calorie expenditure within that hour?

The Science Behind HIIT's Burn: HIIT triggers a phenomenon known as the "afterburn effect," or Excess Post-exercise Oxygen Consumption (EPOC). This means your body continues to burn calories at an elevated rate for hours, and sometimes even days, after your workout is complete. Your body needs to work hard to recover, replenish oxygen stores, clear metabolic byproducts, and repair muscle tissue – all of which require energy.

How to Maximize HIIT for Calorie Burn:

Choose Compound Movements: Exercises that engage multiple muscle groups simultaneously are best. Think burpees, jump squats, mountain climbers, and high knees. These activities require a lot of energy to perform.
Short, Intense Intervals: Aim for intervals of 20-40 seconds of maximum effort. This pushes your body into an anaerobic state, maximizing EPOC.
Brief Recovery: Recovery periods should be short, typically 10-20 seconds. This keeps your heart rate elevated and your body working.
Structure Your Session: A typical HIIT workout might involve 30 seconds of work followed by 15 seconds of rest, repeated for 15-20 minutes. While the workout itself might be shorter than an hour, the total calorie burn, including the EPOC, can be substantial. If you were to extend this into a full hour, you could potentially achieve an astronomical burn, but it would be incredibly challenging and likely not sustainable for most. For the purpose of an "hour of exercise," imagine multiple HIIT circuits interspersed with slightly longer recovery or active recovery periods, keeping the overall intensity very high.

My Experience with HIIT: I used to scoff at HIIT. "Just run for an hour, that's the way to do it," I thought. But after a particularly grueling HIIT session involving burpees and sprints that left me gasping for air, I noticed I felt that elevated heart rate and slight exertion for the rest of the day. The scale started moving faster than ever, and I realized the power of working smarter, not just longer. The key is pushing yourself to your absolute limit during those work intervals.

2. Running (Vigorous Pace)

Running is a classic for a reason. It’s accessible, requires minimal equipment, and is incredibly effective for calorie burning. The key here is the pace. A leisurely jog is great for endurance and recovery, but to maximize calorie burn in an hour, you need to pick up the tempo.

Why Vigorous Running Burns More: Running is a full-body workout that engages your legs, core, and even your arms for propulsion and balance. At a vigorous pace, your heart rate skyrockets, demanding a high oxygen intake and thus burning a significant number of calories. The impact of each stride also contributes to the energy expenditure.

Factors Affecting Calorie Burn While Running:

Pace: The faster you run, the more calories you burn. A pace of 8-10 miles per hour (mph) will burn significantly more than a 5 mph pace.
Terrain: Running uphill or on uneven surfaces requires more effort and therefore burns more calories than running on a flat, smooth track.
Weight: As mentioned, your body weight is a huge factor.

Estimating Calorie Burn: For a 155-pound person, running at a 10 mph pace (6-minute mile) for one hour could burn upwards of 1,000 calories. Even at a still vigorous 8 mph pace (7.5-minute mile), that same individual could burn around 800-900 calories. This is why running, when done intensely, remains a top contender.

3. Swimming (Vigorous Pace)

Swimming is often touted as a fantastic full-body workout, and it truly is. It's low-impact, making it ideal for those with joint issues, but don't let that fool you; it's a calorie-burning powerhouse when done with intensity.

The Swimming Advantage: When you swim, you're working against the resistance of the water. This resistance engages virtually every muscle group – your legs are kicking, your core is stabilizing, and your arms and back are propelling you forward. Furthermore, your body expends energy to stay warm in cooler water, contributing to the overall calorie burn.

Maximizing Calorie Burn in the Pool:

Stroke Choice: Strokes like the butterfly and the freestyle (when swum with power) are generally more demanding and thus burn more calories than breaststroke or backstroke.
Intensity and Intervals: Similar to running, the faster and more continuously you swim, the more calories you'll burn. Incorporating interval training in the pool – swimming laps at a high intensity with short rests – will boost your caloric expenditure.
Water Temperature: Slightly cooler water can increase calorie burn as your body works to maintain its core temperature.

Calorie Estimates: A vigorous swimming session, perhaps involving sprints and varied strokes, could see a 155-pound individual burning around 700-850 calories in an hour. This makes it a very strong contender for the top spot, especially for those seeking a lower-impact option.

4. Cycling (Vigorous Pace)

Cycling, whether outdoors or on a stationary bike, is another excellent way to torch calories. Like running, the key to maximizing burn lies in the intensity and resistance.

Why Cycling is a Calorie Burner: Cycling primarily works your lower body – quadriceps, hamstrings, glutes, and calves. However, maintaining an upright posture and pedaling efficiently also engages your core and upper body to some extent. When you increase the resistance or speed, your heart rate climbs, and your muscles demand more oxygen, leading to a higher calorie burn.

Boosting Your Cycling Calorie Burn:

Speed and Resistance: The faster you pedal and the higher the resistance you use, the more calories you'll burn. On a stationary bike, increasing the incline or resistance levels is crucial. Outdoors, tackling hills or maintaining a high speed on flat terrain will do the trick.
Intervals: Alternating between high-intensity bursts and moderate recovery periods (cycling sprints) is highly effective for calorie expenditure.
Body Position: A more aerodynamic, bent-over position can sometimes increase the effort required, especially at higher speeds.

Calorie Figures: A vigorous cycling session, maintaining a speed of 16-19 mph, can burn approximately 700-900 calories per hour for a 155-pound individual. Indoors, pushing hard on a spin bike with significant resistance can yield similar results.

5. Boxing (Sparring or Heavy Bag Work)

Boxing is a full-body, high-intensity activity that is incredibly demanding and therefore, a fantastic calorie burner. It requires strength, speed, agility, and cardiovascular endurance.

The Boxing Burn: A boxing workout typically involves a combination of punching, footwork, and defensive maneuvers. Punching, especially with speed and power, engages your core, shoulders, arms, and back. The constant movement and footwork keep your heart rate elevated. Sparring, in particular, is incredibly demanding as you're reacting to an opponent, requiring explosive movements and constant engagement.

Maximizing Calorie Burn in Boxing:

Intense Rounds: Focus on high-intensity rounds with minimal rest. Mimic a professional fight structure (e.g., 3-minute rounds with 1-minute rest) but push the intensity during the work periods.
Heavy Bag Work: Hitting a heavy bag with power and speed, incorporating combinations and footwork, is a great way to simulate the demands of a fight.
Combination Training: Work on varied and explosive punch combinations.
Incorporating Other Elements: Some boxing routines include jump rope, shadow boxing, and conditioning exercises, further increasing the overall calorie expenditure within an hour.

Calorie Estimates: An hour of vigorous boxing, especially sparring, can easily burn between 700-900+ calories for a 155-pound person. The sheer demand on your cardiovascular system and the engagement of so many muscle groups make it a top-tier calorie burner.

6. Cross-Country Skiing

This might surprise some, as it's not as commonly accessible in all regions, but cross-country skiing is widely recognized as one of the most demanding cardiovascular activities, leading to an exceptionally high calorie burn.

Why Skiing is a Calorie Furnace: Cross-country skiing is a true full-body workout. You're using your legs to propel yourself forward, your arms and upper body to push with the poles, and your core for stability. It mimics the demands of running but adds the upper body component and the resistance of moving over snow. It requires immense cardiovascular endurance and muscular strength.

Intensity is Key: Like other activities, the intensity at which you ski directly impacts calorie burn. Skiing at a brisk pace, especially over varied terrain (uphill and downhill), will yield the highest results.

Calorie Estimates: A vigorous hour of cross-country skiing can burn an astonishing 800-1,200 calories for a 155-pound individual. This places it at the very top of the list for calorie-burning potential.

7. Stair Climbing (Brisk Pace)

The humble staircase can be a powerful tool for calorie burning. It’s a functional exercise that engages large muscle groups and can be incredibly intense.

The Stair Climbing Advantage: Climbing stairs works your glutes, hamstrings, quadriceps, and calves intensely. It's a form of resistance training combined with cardiovascular work. The constant act of lifting your body weight against gravity demands significant energy.

How to Maximize Stair Climbing Burn:

Pace: The faster you ascend the stairs, the higher your heart rate and calorie burn will be.
Duration: Sustaining this for a full hour, perhaps by finding a tall building or using a stair climber machine at the gym, is key.
Variations: Incorporating double steps, skipping steps, or carrying light weights can further increase the challenge.

Calorie Estimates: Brisk stair climbing can burn between 600-1,000 calories per hour for a 155-pound individual, depending heavily on the pace and effort. Using a stair climber machine set to a challenging program can also achieve high results.

8. Jump Rope

Don't underestimate the power of this childhood pastime! Jump roping, when done at a vigorous pace, is an incredibly efficient calorie burner and a fantastic cardiovascular workout.

The Jump Rope Burn: Jumping rope engages your calves, quadriceps, hamstrings, and glutes. It also requires coordination and engages your core for stability. The constant, repetitive jumping elevates your heart rate significantly. The added benefit is the improvement in coordination and agility.

Maximizing Calorie Burn with a Jump Rope:

Pace: The speed at which you turn the rope and jump is critical. Aim for a fast, consistent pace.
Intervals: Incorporating intense bursts of jumping with brief recovery periods will maximize the calorie burn and the afterburn effect.
Variations: Once you're proficient, try double unders (two rope revolutions per jump), high knees, or alternating foot jumps to increase the intensity.

Calorie Estimates: A vigorous jump rope session can burn anywhere from 600-1,000+ calories per hour for a 155-pound person. It’s a testament to how simple, yet intense, activities can be incredibly effective.

9. Kickboxing and Muay Thai

Similar to boxing, these martial arts are incredibly demanding and offer a phenomenal calorie burn. They combine striking with significant cardiovascular exertion.

The Kickboxing/Muay Thai Advantage: These disciplines involve powerful kicks, punches, knees, and elbows, engaging the entire body. The constant movement, defensive blocks, and offensive strikes elevate your heart rate and demand a lot of energy. The focus on power generation from the hips and core means large muscle groups are constantly in play.

Maximizing the Burn:

High-Intensity Rounds: Focus on performing drills and combinations with maximum power and speed.
Continuous Movement: Keep moving and engaged throughout the hour.
Incorporating Conditioning: Many classes will include burpees, squats, or other bodyweight exercises to further boost the calorie burn.

Calorie Estimates: An hour of intense kickboxing or Muay Thai can result in a calorie burn of 700-1,000+ calories for a 155-pound individual.

10. Rowing (Vigorous Pace)

Rowing, whether on a rowing machine or in a boat, is another exceptional full-body workout that burns a significant number of calories.

The Rowing Powerhouse: Rowing engages about 85% of your muscles. Your legs are the primary drivers, but your back, shoulders, arms, and core are all crucial for the pull. The resistance of the water or the machine requires considerable effort, leading to a high calorie burn and excellent cardiovascular conditioning.

Maximizing Your Rowing Burn:

Proper Technique: Efficient rowing technique maximizes power output and thus calorie burn. Focus on the drive phase (legs push, then back arcs, then arms pull).
Pace and Intensity: The faster you row and the harder you pull, the more calories you'll burn.
Intervals: Incorporating sprints and varied intensity on the rowing machine is very effective.

Calorie Estimates: Vigorous rowing can burn between 600-1,000 calories per hour for a 155-pound individual, depending on the intensity and stroke rate.

Putting It All Together: Which Exercise Wins?

So, to directly answer the question: **What exercise burns the most calories in one hour?** While it's highly dependent on individual factors like weight and intensity, **cross-country skiing** and **high-intensity interval training (HIIT)**, when performed at maximum effort for the duration, generally come out on top, potentially burning upwards of 1,000-1,200 calories per hour for an average individual. Vigorous running, boxing, kickboxing, and swimming are very close contenders, often exceeding 800-900 calories.

However, the "best" exercise isn't solely about the highest calorie burn number. It's about finding an activity you enjoy enough to do consistently, at an intensity that challenges you. An hour of moderate swimming that you find enjoyable might be more beneficial in the long run than a forced, miserable hour of running that you dread.

Beyond the Numbers: The Importance of Consistency and Enjoyment

I cannot stress this enough: the most effective calorie-burning exercise is the one you will actually *do*. I’ve seen clients, and experienced it myself, where the pursuit of the "highest burn" leads to burnout and abandonment. If you hate running, forcing yourself to run for an hour every day won't be sustainable. Instead, find something you genuinely look forward to.

Perhaps you love the feeling of being in the water and find swimming incredibly therapeutic. Maybe you thrive on the adrenaline rush of a boxing class. Or perhaps you prefer the focused, solitary effort of a long bike ride. All of these activities, when performed with sufficient intensity and consistency, will contribute significantly to your calorie expenditure and overall fitness goals.

Creating Your Ultimate Calorie-Burning Workout Plan

For those who want to maximize their one-hour calorie burn and are looking for a structured approach, here’s a framework. This assumes you have a reasonable level of fitness. If you’re a beginner, please start with lower intensities and durations and gradually build up.

Sample High-Calorie Burn Hour: The "Power Hour" (Example for an Average Individual)

This is a hypothetical hour designed to maximize calorie burn. It's extremely demanding and not for the faint of heart.

Time Segment	Activity	Intensity Focus	Estimated Calorie Burn (per 155lb person)
0-10 minutes	Dynamic Warm-up & Light Cardio	Light to moderate	~75-100 calories
10-25 minutes	HIIT Circuit 1 (e.g., Burpees, Jump Squats, Mountain Climbers)	Maximum Effort Intervals (30s work/15s rest)	~250-350 calories
25-40 minutes	Vigorous Running or Cycling	Sustained high intensity (e.g., 8-9 mph run, 15-17 mph cycle)	~250-350 calories
40-55 minutes	HIIT Circuit 2 (e.g., High Knees, Jumping Jacks, Skaters) OR Boxing/Kickboxing Drills	Maximum Effort Intervals	~200-300 calories
55-60 minutes	Cool-down & Static Stretching	Light activity & stretching	~25-50 calories
Total Estimated Burn			~800 - 1,150+ calories

*Disclaimer: These are estimates and can vary significantly based on individual factors and exact intensity.

Tips for Maximizing Your Hour:

Listen to Your Body: This kind of intensity is extreme. If you feel unwell, dizzy, or experience pain, stop immediately.
Proper Nutrition and Hydration: Fuel your body adequately before and after such an intense workout, and stay well-hydrated throughout.
Progression: Don’t attempt this plan on day one. Gradually increase the duration and intensity of your workouts over weeks and months.
Variety: While this plan focuses on high-burn activities, don't be afraid to mix in other exercises you enjoy to prevent boredom and plateaus.

The Role of Strength Training in Calorie Burn

While this article focuses on activities that burn the most calories *during* the hour of exercise, it's crucial to acknowledge the long-term benefits of strength training. Building muscle mass increases your resting metabolic rate, meaning you burn more calories even when you're not exercising.

A comprehensive fitness plan should ideally include both cardiovascular exercise for immediate calorie burn and strength training for sustained metabolic enhancement. Think of cardio as the immediate income and strength training as building an investment portfolio that pays dividends over time.

Frequently Asked Questions About Calorie-Burning Exercise

Q1: How can I accurately track the calories I burn during exercise?

Answer: Accurately tracking calories burned during exercise can be challenging, as most methods provide estimations. However, several tools can offer a reasonable approximation:

Fitness Trackers and Smartwatches: Devices like Apple Watch, Fitbit, Garmin, and others use heart rate data, movement sensors, and user-provided information (age, weight, height, sex) to estimate calorie expenditure. While generally good for steady-state activities, they can be less precise for high-intensity interval training or activities where arm movement is minimal.
Heart Rate Monitors: These devices focus solely on your heart rate. Since calorie burn is closely correlated with heart rate (higher heart rate generally means more calories burned), they provide a good basis for estimation. Many fitness trackers incorporate heart rate monitoring.
Online Calculators and Apps: Numerous websites and apps allow you to input your weight, the type of exercise, and the duration to get an estimated calorie burn. These often use generalized formulas based on MET (Metabolic Equivalent of Task) values for different activities.
Gym Equipment: Treadmills, ellipticals, stationary bikes, and rowing machines often display estimated calorie burn. These estimations are usually based on your entered weight and the intensity of your workout.

It's important to remember that these are all estimates. The most significant factors influencing your actual calorie burn are your individual metabolism, body composition, and the true intensity of your effort, which can be difficult for machines to perfectly capture. For practical purposes, using a combination of a fitness tracker and understanding the general calorie expenditure of different activities can give you a good overall picture.

Q2: Why does high-intensity exercise burn more calories than steady-state cardio?

Answer: High-intensity exercise, like HIIT, burns more calories during the workout itself due to the greater physiological demand placed on your body. When you push yourself to near-maximal effort, your body requires a substantial amount of oxygen to fuel your muscles. This leads to a significantly higher heart rate and respiratory rate, both of which consume a lot of energy.

However, the most significant reason for HIIT's superior calorie-burning reputation lies in the "afterburn effect," or EPOC (Excess Post-exercise Oxygen Consumption). After a very intense workout, your body enters a recovery phase where it needs to work hard to return to its pre-exercise state. This involves processes like replenishing oxygen stores in your muscles and blood, clearing metabolic byproducts (like lactic acid), repairing muscle tissue that may have been damaged, and restoring hormone levels. All of these recovery processes require energy, meaning your metabolism remains elevated and you continue to burn calories at a higher rate for hours after your workout has ended, sometimes even up to 24-48 hours for very intense sessions.

In contrast, steady-state cardio, while excellent for building endurance and burning calories during the workout, typically doesn't trigger such a profound EPOC. Your body is working at a more sustainable level, and the recovery demands are lower. Therefore, while a longer steady-state cardio session can burn a lot of calories, a shorter HIIT session can often result in a comparable or even higher total calorie burn when considering the post-exercise effect.

Q3: Does the type of muscle used in an exercise affect calorie burn?

Answer: Yes, absolutely. The type and amount of muscle used in an exercise have a significant impact on calorie burn. Exercises that engage larger muscle groups tend to burn more calories because these larger muscles require more energy to function.

For example, compound movements that involve the legs, glutes, back, and chest simultaneously (like squats, deadlifts, push-ups, burpees, or compound exercises in swimming and cycling) will burn more calories than isolation exercises that target a single muscle group (like bicep curls or calf raises). This is because a larger number of muscle fibers are activated, and more oxygen is needed to supply these muscles with energy.

Furthermore, the metabolic rate of muscle tissue itself plays a role. Muscle is metabolically active tissue, meaning it burns calories even at rest. Individuals with higher muscle mass generally have a higher resting metabolic rate. Therefore, exercises that effectively recruit and challenge large muscle groups, leading to both immediate calorie expenditure during the activity and contributing to muscle maintenance or growth over time, are generally the most effective for overall calorie burning.

Q4: How important is proper technique for maximizing calorie burn?

Answer: Proper technique is critically important for maximizing calorie burn and, perhaps even more importantly, for preventing injuries. When you execute an exercise with correct form, you ensure that you are engaging the intended muscles efficiently and with the appropriate level of intensity.

For instance, in running, correct form allows for better propulsion and efficiency, enabling you to maintain a faster pace or cover more ground, thus burning more calories. In swimming, proper stroke technique ensures you are moving through the water with the least resistance and maximum propulsion, demanding more from your muscles. In weightlifting or bodyweight exercises like squats and deadlifts, correct form ensures that you are lifting or moving the weight effectively, engaging the primary movers and demanding the most from them.

Conversely, poor technique can lead to several issues:

Reduced Effectiveness: You might be using secondary muscles or compensating in ways that lessen the overall energy expenditure.
Increased Risk of Injury: Faulty form can put undue stress on joints, ligaments, and tendons, leading to strains, sprains, or chronic pain. An injury will, of course, halt your exercise routine entirely, significantly impacting your calorie burn goals.
Plateaus: If your technique is inefficient, you might hit a performance plateau sooner, making it harder to increase intensity or duration and thus limiting your calorie burn potential.

Therefore, investing time in learning and refining proper technique, perhaps through a qualified trainer or by watching reputable instructional videos, is a foundational step for anyone looking to maximize their calorie burn safely and effectively.

Q5: Can I burn a lot of calories in an hour without doing high-impact exercises like running or jumping?

Answer: Absolutely! While high-impact exercises are fantastic for calorie burning, there are many low-impact and non-impact activities that can be incredibly effective. The key, as always, lies in intensity, duration, and engaging large muscle groups.

Here are some excellent low-impact options that can burn a significant number of calories in an hour:

Swimming: As mentioned earlier, vigorous swimming is a top-tier calorie burner. It works your entire body against the resistance of water and is very low-impact on your joints. A challenging swim session can easily rival or surpass the calorie burn of running for many individuals.
Cycling (Outdoor or Stationary): Cycling is a great cardiovascular workout that primarily targets the lower body. By increasing resistance, speed, or tackling hills, you can achieve a very high heart rate and calorie burn without the pounding of high-impact activities. Spin classes, in particular, are designed to be intense and calorie-focused.
Rowing: Rowing machines provide a full-body, non-impact workout that engages a vast percentage of your muscles. By maintaining a strong pace and proper form, you can burn a substantial number of calories.
Elliptical Trainer: These machines offer a cardiovascular workout that mimics running but with no impact. By using the handles and increasing resistance or incline, you can make the elliptical a very effective calorie-burning tool.
Brisk Walking (with Incline): While a casual stroll won't burn as many calories, a brisk walk, especially uphill or on an incline, can significantly elevate your heart rate and calorie expenditure. Using hiking poles can also increase the calorie burn by engaging your upper body.
Water Aerobics (Advanced Classes): While some water aerobics classes are quite gentle, more advanced or "boot camp" style classes can be surprisingly challenging. The water provides resistance, and the movements, when performed with vigor, can lead to a significant calorie burn.

The crucial element is to ensure that you are pushing yourself to a challenging intensity level within these activities. If you are moving at a pace that feels easy, your calorie burn will be lower. So, whether you're swimming laps intensely, tackling steep hills on your bike, or maintaining a high stroke rate on the rower, you can achieve impressive calorie burn without the high impact.
