Cycling: Low-Impact Cardio with Serious Calorie Burn
Cycling delivers high calorie expenditure without the joint stress of running. Whether outdoors or on a stationary bike, it builds cardiovascular fitness and leg strength simultaneously.
Proper Form
Set saddle height so your knee has a slight 25-30 degree bend at the bottom of the pedal stroke.
Keep your upper body relaxed with a slight bend in the elbows to absorb road vibration.
Pedal in smooth circles, pulling up on the backstroke as well as pushing down.
Maintain a cadence of 80-100 RPM for efficient power output and reduced knee stress.
Grip the handlebars lightly; avoid death-gripping which causes neck and shoulder tension.

Cycling on GLP-1 Medications
Cycling is an excellent choice for GLP-1 users because it provides substantial calorie burn with virtually no impact on joints. This matters during weight loss when carrying extra body weight can make high-impact activities uncomfortable. The seated position also reduces the risk of dizziness, a common side effect during GLP-1 dose titration. Indoor cycling is especially practical because you can stop immediately if you feel unwell. Aim for zone 2 heart rate rides of 30-60 minutes, three to four times per week, and pair with resistance training to protect lean mass.

Calorie Burn by Intensity
Cycling at a moderate effort (MET 7.5) burns approximately 500-650 calories per hour for a 170-pound person. Vigorous cycling pushes that to 700-900 calories per hour. The calorie burn scales with resistance and speed, making cycling highly adaptable to your fitness level. Even light cycling at 10-12 mph burns more calories per hour than brisk walking, making it an efficient option for people with limited workout time.
Setting Up Your Bike Correctly
Proper bike fit prevents injury and maximizes power output. Saddle height is the most critical adjustment: too low and you overload your knees, too high and you rock your hips and strain your hamstrings. The general rule is a 25-30 degree knee bend at the bottom of the pedal stroke. Handlebar height should allow a neutral spine with relaxed shoulders. If you experience lower back pain, your reach is likely too long or your saddle too low.
- Saddle height: 25-30 degree knee bend at bottom of stroke
- Saddle fore-aft: kneecap directly over pedal spindle with crank arm horizontal
- Handlebar height: level with or slightly below saddle for road, level or above for comfort
- Cleat position: ball of foot centered over pedal axle
Training Zones for Fat Loss
Zone 2 cycling (60-70% of max heart rate) is the most effective intensity for fat oxidation as a percentage of calories burned. However, higher-intensity intervals burn more total calories per session. The optimal approach combines both: perform most of your cycling at zone 2 for base building and fat burning, and add one interval session per week for metabolic conditioning. A simple interval protocol is 30 seconds hard, 90 seconds easy, repeated 8-10 times.

Frequently Asked Questions
Moderate cycling burns 400-600 calories per hour for most adults. Vigorous cycling or spinning can burn 700-900 calories per hour. Your body weight, intensity, and terrain all affect the exact number.
Cycling is one of the best exercises for weight loss because it burns significant calories with low joint impact, making it sustainable for daily use. Combined with a calorie deficit and adequate protein, cycling accelerates fat loss effectively.
Both are effective. Outdoor cycling often burns slightly more calories due to wind resistance and terrain changes, but stationary bikes offer convenience, safety, and precise control over intensity. Choose whichever you will do consistently.
Aim for 30-60 minutes per session at moderate intensity, three to five times per week. Even 20-minute sessions are beneficial when combined with proper nutrition and strength training.
