A typical 45-minute SoulCycle class burns roughly 400 to 600 calories, with most riders landing somewhere around 500. That range depends heavily on your body weight, how much resistance you add to the bike, and how hard you push during sprints and climbs. A 130-pound rider will burn significantly fewer calories than someone weighing 200 pounds doing the exact same class.
What the Numbers Actually Look Like
The most reliable way to estimate cycling calorie burn is through metabolic equivalents, or METs, which measure how much energy an activity demands compared to sitting still. A standard spin bike class carries a MET value of 9.0, meaning it burns nine times more energy than rest. If you’re riding at higher wattages (200 watts or above), that value climbs to 10.8 or higher.
For context, vigorous stationary cycling burns roughly the same number of calories per hour as running a 10-minute mile. At a 155-pound body weight, that’s about 704 calories per hour. Scale that down to 45 minutes and you’re looking at around 530 calories. At 130 pounds, the same effort yields closer to 440 calories. At 205 pounds, you’re approaching 700.
These numbers assume you’re genuinely working hard throughout the class. If you’re keeping resistance low and coasting through the climbs, your actual burn could drop 20 to 30 percent below those estimates.
Why the Range Is So Wide
Body weight is the single biggest variable. A heavier body requires more energy to do the same physical work, period. But effort level matters almost as much. SoulCycle classes alternate between sprints, seated climbs with heavy resistance, standing climbs, and a short upper-body segment with light weights. How much resistance you dial into the bike during each segment changes your calorie burn dramatically. Two riders sitting side by side can burn vastly different amounts.
Your fitness level also plays a role, though not in the direction most people assume. A well-trained cyclist’s body is more efficient at the same workload, which means slightly fewer calories burned at a given resistance compared to a newer rider. However, fitter riders tend to push harder overall, which usually more than compensates.
How a SoulCycle Class Is Structured
Classes don’t follow a rigid template. Instructors have flexibility to adjust based on the energy in the room, and celebrity instructors in particular tend to put their own spin on things. That said, most 45-minute classes follow a general arc: a light warm-up jog on the bike, followed by progressively harder efforts that alternate between fast-paced sprints and heavy resistance climbs. About two-thirds of the way through, there’s a short arm segment using light hand weights (usually two or three pounds). The class finishes with a final push, often a long standing sprint, before cooling down.
The calorie burn isn’t evenly distributed across these segments. Sprints and heavy climbs are where most of your energy goes. The arm section, while it adds muscle engagement, burns fewer calories per minute than the cycling portions. Recovery songs bring your heart rate down temporarily, which is by design, since those brief recoveries let you push harder on the next effort.
The Afterburn Effect
High-intensity interval work like SoulCycle triggers additional calorie burn after you leave the studio. Your body continues consuming extra oxygen to recover, repair muscle tissue, and restore its resting state. According to the Cleveland Clinic, this post-exercise effect adds roughly 6 to 15 percent on top of whatever you burned during the workout. So if you burned 500 calories in class, you might burn an additional 30 to 75 calories over the following hours. Estimates for how long this elevated burn lasts range from 15 minutes to 48 hours, depending on the intensity of the session.
It’s a nice bonus, but not a game-changer. The bulk of your calorie expenditure happens on the bike.
How Accurate Is Your Fitness Tracker?
If you’re relying on an Apple Watch or similar wearable to count your SoulCycle calories, take the number with a grain of salt. Wrist-based trackers estimate calorie burn using heart rate data, but heart rate is an imperfect proxy for actual energy expenditure, especially during cycling. Your arms are relatively still on a bike, which can confuse wrist-based sensors. Research comparing smartwatch estimates to laboratory-grade metabolic testing has found median errors of 50 to 60 percent for key fitness metrics during cycling. Some watches overestimate, others underestimate, and accuracy varies from person to person.
The calorie number on your screen is best used as a relative measure. If your watch says 520 one class and 580 the next, you probably did work harder the second time. But treating that specific number as gospel isn’t warranted.
Clip-In Shoes Make a Difference
SoulCycle bikes use clip-in pedals, and the studio provides cycling shoes if you don’t have your own. This isn’t just for aesthetics. When your foot is locked into the pedal, you can pull up on the backstroke in addition to pushing down, which engages your hamstrings and calves more fully. With regular sneakers, some of your energy gets absorbed by the shoe’s cushion, and more is wasted just keeping your foot stable on the pedal. Clipping in means more of your effort translates into actual pedal power, which means more calories burned at the same perceived effort level.
How SoulCycle Compares to Other Workouts
At roughly 500 calories per 45-minute session, SoulCycle sits in the upper tier of group fitness classes for calorie burn. For comparison, here’s how vigorous indoor cycling stacks up against running at different body weights over a full hour:
- 130 pounds: approximately 590 calories for both vigorous cycling and running at a 10-minute mile pace
- 155 pounds: approximately 704 calories for both activities
- 180 pounds: approximately 817 calories for both
- 205 pounds: approximately 931 calories for both
These are hour-long estimates, so multiply by 0.75 to approximate a 45-minute class. The takeaway is that a hard SoulCycle class burns calories at roughly the same rate as running, which puts it well ahead of moderate-intensity activities like yoga, walking, or casual biking. The key word is “hard.” The interval structure of a SoulCycle class, with its mix of sprints, climbs, and recovery, keeps average intensity high enough to compete with steady-state running, but only if you’re actually turning up the resistance when the instructor tells you to.
