What Is a Spin Class? What Happens, What to Wear, and Bike Setup

A spin class is a 45 to 60 minute indoor cycling workout set to music. What happens in class, the benefits, shoes and clothes, and how to set up your bike.

A spin class is a group indoor cycling workout, usually 45 to 60 minutes, where an instructor leads the room through hills, sprints, and steady efforts on stationary bikes, set to loud music. You control your own resistance, so the same class works for beginners and regulars, and it is one of the easiest cardio workouts on your joints.

"Spinning" is technically a trademarked program, but people use "spin class" for any instructor-led indoor cycling class. Below: what happens in a class, the terms instructors use, the benefits, what to wear, how to set up your bike, and how to get through your first ride.

What happens in a spin class

Most classes follow the same arc.

Check-in and bike setup (10 minutes before). You get assigned or pick a bike, adjust it to your body, and clip in. Tell the instructor it is your first ride and they will help.
Warm-up (5 minutes). Easy pedaling with light resistance while your legs loosen up.
Main set (30 to 40 minutes). Songs or blocks that alternate between climbs (heavy resistance, slower legs), sprints (lighter resistance, fast legs), and recovery. You will ride seated and standing.
Cool-down and stretch (5 minutes). Easy spinning, then stretches on or off the bike.

Rooms are often dim with colored lights, and the music is loud. Some studios add arm work with light hand weights mid-ride. That is it. There is no choreography test, and nobody can see your resistance knob.

Types of spin classes

Type	What it is like	Good for
Rhythm ride	Pedal on the beat, with choreography like tap-backs and push-ups on the handlebars	People who want a party feel
Performance or metrics ride	Coached to power, cadence, and heart rate, often with a leaderboard or screen	People who like numbers and progress
Interval or HIIT ride	Hard efforts and short recoveries	A short, intense workout
Endurance ride	Longer steady efforts, sometimes 60 to 90 minutes	Outdoor cyclists training indoors
Gym cycling class	Mix of the above, usually included with membership	Trying spin without paying boutique prices

If you liked dance classes or want energy, start with a rhythm ride. If you want to see yourself improve week to week, a metrics-based class gives you numbers to beat.

Spin class terms you will hear

Resistance: how hard the pedals are to push, set by a knob or lever. Turning it up makes a climb. Pressing it down usually stops the flywheel in an emergency.
Cadence or RPM: how fast your legs turn, in revolutions per minute. Typical flat-road cadence is 80 to 110 RPM; climbs are slower.
Saddle or seated: riding sitting down.
Out of the saddle, standing, or "first position up": riding standing, hips over the pedals.
Jog or run: standing with lighter resistance and quicker legs.
Climb: heavy resistance, slower legs, seated or standing.
Sprint: a short all-out effort, usually 15 to 30 seconds.
Tap-back: a rhythm-ride move where you push your hips back over the saddle on the beat while standing.

Benefits of spin class

Harvard Health describes spinning as good for the heart and muscles and easy on the joints, and points to it as a good option for people who have trouble with higher-impact cardio such as running, including people with knee or hip issues. The main benefits:

Cardio fitness. Intervals push your heart rate high, then let it recover, which builds aerobic fitness quickly.
Low impact. Your feet never leave the pedals, so there is no pounding on knees, hips, or ankles.
Leg and glute endurance. Climbs with real resistance work your quads, hamstrings, glutes, and calves.
Calorie burn. Harvard Health's calorie table estimates 210 to 294 calories for 30 minutes of moderate stationary cycling, depending on body weight (125 to 185 pounds). Hard intervals burn more.
It counts toward the guidelines. The CDC recommends 150 minutes of moderate aerobic activity a week. Three 45-minute rides gets you close.

What spin does not do much of: upper body strength, bone loading, and mobility. That is why many regulars pair it with a strength class or yoga. The calm of a vinyasa class is a good counterweight to a loud ride, and our guide to yoga classes for beginners covers how to start.

What to wear to spin class

Bottoms: fitted shorts, bike shorts, or leggings. Avoid loose shorts that bunch on the saddle and wide-leg pants that can catch on the pedals.
Top: a light, sweat-wicking tank or T-shirt. You will sweat more than you expect.
Sports bra: medium support is usually enough, since there is no bouncing like in running, but rhythm rides with standing choreography move more.
Padded shorts (optional): if the saddle hurts after your first few rides, padded bike shorts or a gel seat cover help. Soreness usually fades after three or four rides.
Bring: a full water bottle and a small towel. Many studios provide towels.

Spin shoes: clip-in or sneakers?

Most boutique cycling studios use clip-in pedals and rent shoes at the desk. Clip-ins keep your foot in the right spot and let you pull up as well as push down, which makes hard efforts feel smoother. If you buy your own, match the cleat to the studio's pedals: SPD (two-bolt) and Look Delta (three-bolt) are the common ones. Many gym bikes have dual-sided pedals with a toe cage on one side, so sneakers with a stiff sole work fine.

For a Portland example, JIBE Cycling Studio's Portland studio page lists shoe rentals for $3 and says its bikes take SPD clips if you bring your own.

How to set up a spin bike

A bad setup is the main reason first rides hurt. Ask staff to check you, and use these rules:

Seat height: standing next to the bike, set the saddle at about hip-bone height. On the bike, your knee should have a slight bend at the bottom of the pedal stroke, never locked straight.
Seat position (fore and aft): with the pedals level, your front knee should sit roughly over the ball of your foot.
Handlebars: start level with or slightly higher than the seat. Higher is more comfortable for beginners and easier on your lower back.
Clipping in: point your toe down and press the cleat into the pedal until it clicks. To unclip, twist your heel outward. Practice once before class starts.

Write down your settings (most bikes have numbered posts) so the next class takes 30 seconds to set up.

Tips for your first spin class

Arrive 10 to 15 minutes early for setup and to tell the instructor it is your first ride.
Pick a bike in the middle or back. You can watch the room and nobody is watching you.
Ride at about 70 percent. Everyone is tempted to match the room. Finish your first class wanting more instead of nauseous at minute 20.
Always keep some resistance on. Pedaling fast with no resistance bounces you on the saddle and is hard on your knees.
Sit down when you need to. Standing work is optional.
Drink water during recoveries, not in the middle of a sprint.
Wipe down your bike after class. More on that in our fitness class etiquette guide.

How much a spin class costs

Boutique cycling classes typically run $25 to $42 for a drop-in, with intro offers and packs lowering the price. SoulCycle's New York pricing lists $42 for a single ride and $25 for a first ride as of October 2026. Gym cycling classes are usually included with membership. Our full breakdown of how much workout classes cost covers packs, memberships, and ClassPass.

Spin classes in Portland, Maine

Portland has a small, strong cycling scene. JIBE Cycling Studio is on Hanover Street in the Bayside neighborhood, with a second location in Yarmouth, and runs a 45-minute signature rhythm ride plus a 90-minute "Epic Ride." Rêve on Forest Avenue rounds out the city's dedicated cycling options. Gyms across the area also run cycling classes. Our Portland class directory covers the rest of the local scene.

Spin is one of the easiest classes to turn into a habit, because the room does the motivating. A standing ride with a friend helps even more. Full disclosure: we built Corvi for that part. Book your ride with the studio, then check in on Corvi to keep a weekly streak and see which classes your friends are taking. It is free and does not handle booking or payments.

Common questions

Is spin class good for beginners?

Yes. You control the resistance knob on your own bike, so a beginner and a regular can ride side by side at very different efforts. Arrive early so staff can set up your bike, ride at about 70 percent of what the instructor calls for in your first class, and sit down whenever you need to. Most people feel comfortable by their third ride.

How many calories does a spin class burn?

It depends on your body weight and how hard you ride. Harvard Health estimates that 30 minutes of moderate stationary cycling burns about 210 calories for a 125-pound person and about 294 for a 185-pound person. A 45-minute class with hard intervals will burn more. Bike screens and fitness trackers give rough estimates, not exact numbers.

What should I wear to a spin class?

Wear fitted shorts or leggings that will not catch on the seat, a breathable top that wicks sweat, and a supportive sports bra if you wear one. Padded bike shorts help if the saddle bothers you. Bring water and a small towel. Rent clip-in shoes at the studio or wear stiff-soled sneakers if the bikes have cages.

Do you need special shoes for spin class?

Most boutique cycling studios use bikes with clip-in pedals and rent cycling shoes for a few dollars a class. If you buy your own, check which cleat the studio's bikes take, usually SPD or Look Delta. Many gym bikes have dual pedals with toe cages on one side, so sneakers work there.

How often should you do spin class?

Two or three rides a week is a common rhythm, with rest or a different workout in between. Spin is low impact, so your joints usually handle frequent rides well, but your legs still need recovery. Pairing spin with a strength or yoga class covers the muscles and mobility that cycling misses.
