How Many Calories Does Indoor Cycling Burn?
Indoor cycling puts you on a stationary bike in a darkened studio, typically riding to a curated playlist while an instructor calls out cadence targets, resistance changes, and occasional standing climbs. Unlike outdoor riding, you control every variable in real time: dial the resistance knob up and you're grinding through a steep hill, back it off and you're spinning out a fast flat. The format rewards both the person who wants a low-impact cardio session on tired legs and the person who wants to push lactate threshold intervals until their quads scream. That flexibility is what makes it genuinely useful across fitness levels.
Indoor Cycling calories by weight & duration
| Body weight | 15 min | 30 min | 45 min | 60 min |
|---|---|---|---|---|
| 125 lb | 99 | 198 | 298 | 397 |
| 150 lb | 119 | 238 | 357 | 476 |
| 175 lb | 139 | 278 | 417 | 556 |
| 200 lb | 159 | 318 | 476 | 635 |
| 225 lb | 179 | 357 | 536 | 714 |
The roughly 492 calories per hour figure is a research-based estimate for a 155 lb person riding at a moderate-to-vigorous effort, and your actual burn will be higher or lower depending on your weight, fitness level, and how hard you push the resistance. You can log your indoor cycling sessions in the Mariposas app to track how your calorie expenditure adds up over time.

What to expect in a indoor cycling class
Your first class will open with a few minutes of low-resistance pedaling to get the legs warm, then the instructor will start calling cues like 'add two turns of resistance' or 'bring your cadence up to 90 RPM.' You'll alternate between seated efforts, standing climbs, and occasional sprint pushes, with brief recovery valleys in between. The class follows the music in structure, so heavier beats usually signal harder efforts and breakdowns signal a chance to catch your breath. Expect your legs to feel the work more than your lungs for the first few sessions, especially in the quads and hip flexors.
Tips for your first indoor cycling class
- Set up the bike before class starts. Seat height is the big one: when the pedal is at its lowest point, your knee should have a slight bend, not be fully locked out. A staff member or the instructor can help you dial this in, and getting it right prevents the knee discomfort that makes new riders quit early.
- Ignore what everyone else is doing with resistance for your first two or three sessions. The person next to you may have been riding for years. Your only job is to find an effort level that feels challenging but lets you breathe and finish the class.
- Clip-in cycling shoes make a real difference in how efficiently you can pedal, but you do not need to own a pair on day one. Most studios rent them or have loaners. Once you know you like the format, it's worth investing in a pair.
- Drink more water than you think you need. The room gets hot, fans or not, and you will sweat heavily. Coming in already well-hydrated and keeping a bottle on the bike makes the back half of class noticeably easier.
What affects how many calories indoor cycling burns
The 492 calorie figure applies to a 155 lb person riding at a solid, sustained effort. A heavier rider will burn more per hour at equivalent effort, and a lighter rider will burn less, simply because moving greater body mass requires more energy output. How aggressively you use the resistance knob matters enormously: a rider who keeps the tension light the whole class is doing a fraction of the work of someone who actually leans into the climbs and interval pushes the instructor calls.
Three things move your number most: body weight (a heavier body burns more for the same activity, that's why the table runs from 125 to 225 lb), duration (calories scale with time), and intensity. A indoor cycling you push hard burns more than an easy one, because effort is what the MET value of 7 represents, an average for this activity. Your fitness level and how much you rest between efforts shift it too, so treat these as a solid estimate rather than an exact count.
How we calculate indoor cycling calories
Every number here uses the standard energy-expenditure formula: calories ≈ MET × body weight (kg) × time (hours). The MET value of 7 for indoor cycling comes from the published Compendium of Physical Activities, the same reference researchers and fitness trackers use. We convert your weight to kilograms and multiply through, no fudge factors. See our methodology for the full formula and sources.
