Mowing your lawn can burn anywhere from 200 to 600 calories per hour, depending on factors like your weight, the mower type, and the terrain. This guide will help you figure out your lawn mowing calorie expenditure and how much exercise lawn mowing truly is.
Mowing the lawn is a classic chore, but it’s also a surprisingly effective way to get your body moving. Many people wonder about the precise calories burned mowing grass, and the truth is, it’s not a one-size-fits-all answer. Your weight, the type of mower you use, the slope of your yard, and even how fast you push it all play a role in quantifying mowing calories. Think of it as your weekly dose of lawn care physical activity.

Fathoming Your Lawn Mowing Calorie Burn
Let’s dive deeper into what influences how many calories you burn while tending to your turf. It’s more than just pushing a machine; it’s a full-body workout in disguise.
Factors Affecting Calorie Expenditure
Several elements contribute to your lawn mowing calorie expenditure. By understanding these, you can get a more accurate picture of your workout.
- Your Body Weight: This is a primary factor. A heavier person will naturally burn more calories doing the same activity as a lighter person because they have more mass to move.
- Mower Type:
- Push Mowers (Manual Reel Mowers): These are the most physically demanding. You are literally providing all the power. Expect a higher calorie burn.
- Walk-Behind Gas Mowers: These require pushing, but the engine does some of the work. Your effort is less than a reel mower.
- Self-Propelled Gas Mowers: These do most of the forward motion for you, reducing your physical effort and therefore your calorie burn.
- Riding Mowers: These are essentially like driving. While you’re out in the fresh air, the calorie burn is significantly lower, comparable to sitting.
- Robotic Mowers: These do the work for you, offering virtually no calorie burn.
- Terrain:
- Flat Yards: Require steady effort.
- Hilly or Sloped Yards: These are much more challenging. Pushing or walking up inclines significantly increases your heart rate and calorie burn.
- Pace and Intensity: How fast you walk and push the mower, and how vigorously you work, directly impacts the calories you burn. A brisk pace will burn more than a leisurely stroll.
- Grass Type and Length: Densely packed or long, wet grass offers more resistance, making the job harder and burning more calories.
- Cutting Width and Deck Size: A wider mower might mean fewer passes, but if the resistance is higher, it could still equate to a similar or even higher overall burn.
Estimating Your Lawn Mowing Calorie Burn
While precise numbers are elusive without specialized equipment, we can use estimations. These are based on general MET (Metabolic Equivalent of Task) values and your body weight. The MET value represents how much energy an activity uses compared to resting.
General MET Values for Mowing:
- Pushing a non-self-propelled mower: 4.5-6.0 METs
- Pushing a self-propelled mower: 3.0-4.0 METs
- Riding a mower: 2.0-3.0 METs
Formula for Estimating Calories Burned:
Calories Burned per Minute = (METs × Body Weight in kg × 3.5) / 200
Let’s break this down with an example:
Example: Sarah weighs 140 lbs (approximately 63.5 kg). She has a half-acre yard with some gentle slopes and uses a walk-behind, non-self-propelled mower, working at a moderate pace. We can estimate her MET value at around 5.0.
Calories Burned per Minute = (5.0 × 63.5 kg × 3.5) / 200
Calories Burned per Minute = 1111.25 / 200
Calories Burned per Minute ≈ 5.56 calories per minute
If Sarah mows for 45 minutes:
Total Calories Burned = 5.56 calories/minute × 45 minutes
Total Calories Burned ≈ 250 calories
Now, let’s consider Mark, who weighs 180 lbs (approximately 81.6 kg). He has a similar yard but uses a self-propelled mower at a brisk pace. We can estimate his MET value at around 3.5.
Calories Burned per Minute = (3.5 × 81.6 kg × 3.5) / 200
Calories Burned per Minute = 1004.4 / 200
Calories Burned per Minute ≈ 5.02 calories per minute
If Mark mows for 45 minutes:
Total Calories Burned = 5.02 calories/minute × 45 minutes
Total Calories Burned ≈ 226 calories
Notice how even with a heavier weight, the self-propelled mower reduced Mark’s overall calorie burn per minute compared to Sarah’s non-self-propelled mower. This highlights the importance of mower type.
Quantifying Mowing Calories: A Comparative Look
To better grasp your lawn mowing calorie expenditure, let’s compare it to other common activities. This helps contextualize how much exercise is lawn mowing.
| Activity | METs (Approximate) | Calories Burned per Hour (150 lbs person) | Calories Burned per Hour (200 lbs person) |
|---|---|---|---|
| Walking (3.0 mph) | 3.5 | 280 | 375 |
| Jogging (5.0 mph) | 8.3 | 665 | 890 |
| Cycling (leisurely) | 4.0 | 320 | 430 |
| Pushing non-self-propelled mower | 5.0 | 400 | 535 |
| Pushing self-propelled mower | 3.5 | 280 | 375 |
| Riding a mower | 2.5 | 200 | 265 |
| Gardening (light) | 3.0 | 240 | 320 |
| Gardening (heavy) | 4.5 | 360 | 480 |
| Swimming (leisurely) | 5.8 | 465 | 620 |
(Note: Calorie burn figures are estimates and can vary.)
As you can see, mowing with a non-self-propelled mower can be as effective as a brisk walk or light cycling for burning calories.
The Aerobic Exercise Mowing Advantage
When you’re out mowing, you’re engaging in aerobic exercise mowing. This type of exercise is crucial for cardiovascular health.
What is Aerobic Exercise?
Aerobic exercise, also known as cardiovascular exercise, is any physical activity that:
- Increases your heart rate and breathing rate.
- Uses large muscle groups.
- Can be sustained for a period of time.
Mowing the lawn, especially with a push mower on varied terrain, definitely fits this description. Your heart pumps harder to deliver oxygen to your muscles, and your lungs work to take in more air. This sustained effort strengthens your heart and lungs over time.
Cardiovascular Benefits
Engaging in regular aerobic exercise mowing contributes to:
- Improved Heart Health: Lowers blood pressure, reduces the risk of heart disease, and improves cholesterol levels.
- Increased Stamina: Your body becomes more efficient at using oxygen, leading to less fatigue during physical activities.
- Weight Management: Burning calories is a key component of maintaining a healthy weight or losing excess weight.
- Mood Enhancement: Physical activity releases endorphins, which have mood-boosting effects and can help reduce stress and anxiety.
- Better Blood Sugar Control: Improves insulin sensitivity, which is beneficial for preventing or managing type 2 diabetes.
Yard Work Fitness Benefits Beyond Calorie Burn
The yard work fitness benefits extend far beyond just the calories you burn. It’s a comprehensive approach to health.
Strength and Endurance
Pushing a mower, especially a manual reel mower or navigating slopes, works your leg muscles (quadriceps, hamstrings, calves), glutes, and core. Carrying bags of clippings or using tools for other lawn care physical activity can also engage your upper body and arms. Over time, this can lead to increased muscle strength and endurance.
Flexibility and Balance
Reaching, bending, and maneuvering around obstacles in your yard can improve your flexibility and range of motion. Maintaining balance on uneven ground also engages your stabilizing muscles, contributing to better overall balance and reducing the risk of falls.
Mental Well-being
The act of working outdoors has significant mental health benefits. Connecting with nature, the satisfaction of a job well done, and the physical exertion can all contribute to stress reduction and improved mental clarity. It’s a form of active meditation for many.
Mowing Calories in Relation to Daily Needs
Understanding how many calories does mowing a lawn burn is also useful when considering your daily calorie needs.
Your Basal Metabolic Rate (BMR)
Your BMR is the number of calories your body burns at rest to maintain basic functions like breathing, circulation, and cell production. This is the minimum number of calories you need each day.
Total Daily Energy Expenditure (TDEE)
Your TDEE is your BMR plus the calories you burn through all your physical activities throughout the day, including exercise, walking, and even fidgeting.
TDEE = BMR + Activity Level + Thermic Effect of Food
Mowing the lawn contributes to the “Activity Level” component of your TDEE. For someone with a moderate activity level, adding an hour of mowing can significantly boost their daily calorie expenditure.
Example: A person with a BMR of 1500 calories per day might have a TDEE of around 2000-2200 calories if they have a sedentary to lightly active lifestyle. If they then spend an hour mowing, adding another 400-500 calories burned, their TDEE for that day increases substantially.
Mowing and Weight Management
To lose weight, you generally need to consume fewer calories than your body burns (calorie deficit). Incorporating activities like mowing into your routine can help create this deficit. For instance, if your daily calorie needs are 2200 and you burn an extra 400 calories mowing, you would need to consume around 1800 calories to be in a deficit.
Gardening Calorie Comparison: Mowing vs. Other Chores
It’s useful to compare lawn mowing calorie expenditure to other outdoor chores calorie burn and gardening calorie comparison to see where it fits.
| Outdoor Chore/Activity | METs (Approximate) | Calories Burned per Hour (150 lbs person) | Calories Burned per Hour (200 lbs person) |
|---|---|---|---|
| Raking leaves (moderate) | 3.5 | 280 | 375 |
| Shoveling snow (moderate) | 6.0 | 480 | 640 |
| Weeding a garden | 3.0 | 240 | 320 |
| Planting trees/shrubs | 4.0 | 320 | 430 |
| Pushing non-self-propelled mower | 5.0 | 400 | 535 |
| Mowing with self-propelled mower | 3.5 | 280 | 375 |
This table illustrates that pushing a non-self-propelled mower is a vigorous activity, often burning more calories than raking or weeding. It can be comparable to some forms of shoveling or planting.
Maximizing Your Lawn Mowing Workout
Want to get the most out of your lawn care physical activity? Here are some tips:
- Choose the Right Mower: If your goal is fitness, opt for a manual reel mower or a non-self-propelled gas mower.
- Vary Your Pace: Don’t just walk; try brisk intervals.
- Navigate Hills: If you have slopes, tackle them strategically. Walking up hills is a great calorie burner.
- Mow in Sections: If you have a large yard, break it up. This allows for more focused bursts of activity.
- Combine with Other Chores: Follow mowing with some weeding, raking, or even pushing a wheelbarrow. This adds to your overall outdoor chores calorie burn.
- Stay Hydrated: Drink plenty of water before, during, and after your mowing session.
- Warm-Up and Cool-Down: A few minutes of stretching before and after can help prevent injury and improve your workout.
Frequently Asked Questions (FAQ)
Q: How many calories do I burn pushing a lawn mower for 30 minutes?
A: If you weigh 150 lbs and use a non-self-propelled mower at a moderate pace (METs of 5.0), you would burn approximately 200 calories in 30 minutes (400 calories/hour / 2 = 200 calories). For a 200 lb person, this would be about 267 calories.
Q: Is mowing the lawn good aerobic exercise?
A: Yes, mowing the lawn, especially with a push mower, is considered aerobic exercise. It elevates your heart rate and breathing, strengthens your cardiovascular system, and helps improve endurance.
Q: Does the type of grass affect calorie burn?
A: Yes. Denser, thicker, or longer grass offers more resistance, requiring more effort to push the mower through. This increased effort leads to a higher lawn mowing calorie expenditure.
Q: Can riding a mower burn any calories?
A: Riding a mower burns significantly fewer calories than walking or pushing a mower, but it still burns calories compared to being completely sedentary. It’s more akin to a low-intensity activity like a very leisurely stroll. The primary benefit is being outdoors and engaging in a chore.
Q: How does mowing compare to gardening in terms of calories burned?
A: Pushing a non-self-propelled mower (around 400-535 calories/hour for a 150-200 lb person) generally burns more calories than light gardening activities like weeding (around 240-320 calories/hour). However, strenuous gardening tasks like digging or moving heavy soil can be comparable to or even exceed the calorie burn of mowing.
In conclusion, how many calories does mowing a lawn burn is a dynamic question with an answer that varies significantly. It’s a practical and effective way to incorporate lawn care physical activity into your week, offering tangible yard work fitness benefits and contributing positively to your overall health and daily calorie needs.
