Indoor Cycling Calorie Calculation Method
Indoor cycling calorie burn is calculated using MET (Metabolic Equivalent of Task) values. MET ranges from 6.8 (low resistance) to 12.5 (maximum resistance) — nearly double the difference. The formula is: Calories = MET × weight (kg) × time (hours).
Indoor cycling is a low-impact exercise that's easy on the knees while effectively strengthening lower body muscles (quads, hamstrings, calves). Consistent 30–60 minute sessions 3–5 times per week yield measurable cardiorespiratory and fat loss improvements.
Using HIIT intervals on a stationary bike maximizes calorie efficiency. A Tabata-style protocol (20 sec sprint + 40 sec recovery, repeated 10–15 times) can burn 400–500 kcal in just 30 minutes.
Frequently Asked Questions
Outdoor cycling often burns more calories due to wind resistance, hills, and terrain variations. However, spin class maintains consistently high intensity throughout the session, which can match or exceed outdoor calorie expenditure for the same duration.
When seated, your knee should be slightly bent (5–10 degrees) at the bottom of the pedal stroke. Too low strains the knee; too high causes hip rocking and lower back strain. Correct positioning is essential for both calorie efficiency and injury prevention.
