How Many Calories Do You Burn In A SoulCycle Class? | True Range

Calorie Burn In SoulCycle Sessions: What Counts

Studio cycling turns resistance, cadence, and music into a fast aerobic session. Your burn comes from three levers: effort (how hard you push the pedals), body size (more mass needs more energy), and time on the bike. Age, fitness, and room temperature nudge the total too, but those three set the baseline.

Scientists use METs (metabolic equivalents) to translate effort into calories. A typical rhythm ride sits around 9 METs for a formal spin class, while a steady, moderate pace hovers near 6.8 METs. Calorie math uses a simple rule: calories per minute equal METs × 3.5 × body weight in kilograms ÷ 200. Multiply by your minutes to get a class total.

SoulCycle’s standard studio block runs 45 minutes. Some rooms schedule 30-minute sprints or longer theme rides, yet the 45-minute block is the sweet spot most riders book. That time window frames the ranges in the next table.

Broad Estimates For A 45-Minute Class

Use this wide table as a quick reality check. It shows two effort bands pulled from established MET values for indoor bikes: a steady moderate ride and a punchier spin-style ride. Numbers are rounded for readability.

Rider Weight	Moderate (~6.8 MET)	Spin Class (~9.0 MET)
120 lb (54.4 kg)	290–315 kcal	380–410 kcal
150 lb (68.0 kg)	365–395 kcal	485–520 kcal
180 lb (81.6 kg)	440–475 kcal	580–625 kcal
210 lb (95.3 kg)	515–555 kcal	680–730 kcal
240 lb (108.9 kg)	590–635 kcal	775–835 kcal

Dial resistance down or up and the totals swing fast. Once you’ve set your daily calorie needs, these numbers help you plan fueling without guesswork.

Why Two People In One Class See Different Numbers

Bike computers, wearables, and studio screens rarely match because they use different inputs. Some read power, some estimate from heart rate, and some blend both. Two riders can work side-by-side at the same cadence and hit very different watt outputs because resistance and muscle efficiency differ.

Body weight also moves the needle. The MET formula scales linearly with kilograms. A heavier rider doing the same relative effort burns more energy per minute. That’s why leaderboards and wrist trackers never tell the full story across a mixed room.

Effort rating matters too. The talk test is a handy cue: if you can speak in short phrases, you’re in a moderate zone; if talking feels choppy or breathless, you’re near vigorous. Pair that with your heart-rate zone targets and you’ll land in a repeatable effort band from week to week. See the CDC intensity guide for a clear, plain-English refresher.

Turn METs Into Your Own Estimate

Grab your weight in kilograms, pick an effort band, and run the math. Here’s the step-by-step flow for a 45-minute block.

Step 1: Convert Your Weight

Divide pounds by 2.205 to get kilograms. A 170-pound rider lands near 77.1 kg.

Step 2: Pick A Realistic Effort Band

Use 6.8 METs for a smooth, steady ride and 9.0 METs for a rhythm ride packed with sprints, heavy climbs, and jogs out of the saddle. If you push max resistance often, a higher MET value applies and the total climbs. The Compendium lists an explicit entry for an RPM/spin bike class at 9 METs; you can scan the official MET table to see more levels.

Step 3: Do The Minutes Math

Calories per minute = METs × 3.5 × kg ÷ 200. For our 170-pound rider at 9 METs: 9 × 3.5 × 77.1 ÷ 200 ≈ 12.1 calories per minute. Multiplied by 45 minutes, that’s ~545 calories.

Want a calmer day? Swap 9 for 6.8 in the same math and you get ~411 calories for the very same class length.

How Class Length Changes The Total

Time multiplies everything. A 30-minute pop-up ride trims your total, while an hour on the bike stretches it. The table below uses a 150-pound rider to keep the math clean.

Class Length	Moderate (~6.8 MET)	Spin Class (~9.0 MET)
30 minutes	245–265 kcal	325–350 kcal
45 minutes	365–395 kcal	485–520 kcal
60 minutes	485–525 kcal	650–695 kcal

Short blocks still count. Stack two 30-minute rides in a week and you match a single long day while giving your legs more recovery between sessions.

Ways To Nudge Your Burn Up Or Down

Set Your Bike Well

Seat height, fore-aft, and handlebar reach change how much muscle you recruit. A proper fit helps you hold power without knee wobble or lower-back tightness. Ask your instructor to check your setup before warm-up.

Use Resistance With Intention

Spin-style rides mix sprints with heavy climbs. Turning the knob until the pedals feel dense increases watt output and, with it, calorie burn. Keep cadence controlled; speed alone with tiny resistance doesn’t move the needle.

Ride Your Heart-Rate Zones

Most watches can guide you into zones that line up with moderate and vigorous work. Spend more minutes in Zone 3-4 for a classic cardio session, then add brief Zone 5 pushes for intervals once you’re ready. If you need a refresher, the AHA target heart-rate chart gives simple ranges by age.

Fuel And Recover

Arrive hydrated and eat a small carb-lean snack 60–90 minutes beforehand if you train better with food. After class, grab protein and fluids so you bounce back for the next session.

Sample Targets By Experience Level

New To The Bike

Keep resistance light-to-moderate, sit tall, and learn smooth circles through the pedals. Aim for a steady 70–85 RPM with occasional short pickups. Stay near the moderate band for most of the ride.

Building Consistency

Alternate two minutes steady with one minute strong, repeating through the middle of class. Turn the knob enough that you feel clear pressure on climbs, then spin easy for recovery. Watch average watts rise week by week.

Chasing Performance

Layer in three to five 30- to 60-second sprints above your usual hill load with long easy spins between. Keep form clean out of the saddle, hips steady over the pedals, and eyes up.

Gear And Tracking Tips

Heart-Rate Straps

Wrist sensors sometimes lag during surges. A chest strap catches changes sooner, which helps if you ride by zones.

Power Readouts

Some studios show watts. Use average watts for the whole ride as a simple progress marker. If that number climbs with the same perceived effort, your fitness is moving in the right direction.

Calorie Numbers On Screens

Treat them as estimates. Devices use assumptions about weight and fitness. Your own calculation with METs and minutes gives a consistent personal yardstick over time.

Safety, Setup, And Small Tweaks

Saddle And Hand Position

Set saddle height so you keep a soft bend in the knee at the bottom of the stroke. Slide the saddle so your knee stacks above the ball of the foot when the pedals pause level. Hands should rest without shrugging the shoulders.

Breathing And Posture

Ribs up, shoulders easy, and a light grip on the bars. Breathe through the nose when you can, then through the mouth on heavy pushes. Smooth breathing helps you manage long climbs.

When To Pull Back

If form breaks or you feel dizzy, sit down, lighten resistance, and reset. You’ll get more total work by keeping control than by grinding through sloppy reps.

Frequently Heard Claims, Tested

“The Room Heat Melts Fat”

Sweat shows fluid loss, not fat loss. The benefit you get is a bit more heart-rate drift for the same load. Rehydrate and you’re back at baseline.

“Going Faster Beats Adding Load”

Fast spins with tiny resistance add little power. A slower cadence with a firm hill moves more work to the legs and lifts total energy cost.

“Arm Tracks Are The Secret”

Light dumbbells help posture and rhythm. The bike is still the main engine, so put most of your effort budget into the pedals.

Bring It Together

A rhythm-based class can be a 350-calorie day or an 800-calorie day. The gap comes from minutes, resistance, body size, and how much time you spend at strong efforts. Tune those knobs and you’ll get repeatable results that match your goals. Want a fuller read on shaping intake around training? Try our calorie deficit guide.
