You’ve seen them. Those people walking out of a darkened room, drenched in sweat, looking like they just survived a mild monsoon but wearing the biggest grins you've ever seen. They’re talking about "resistance," "intervals," and someone named "the instructor" who apparently changed their life between 7:15 and 8:00 AM. If you've ever stood outside a studio door hearing muffled techno beats and wondered, spinning what is it and do I actually need a special pair of shoes for this, you aren't alone. It’s basically indoor cycling, but with a lot more soul and a lot less coasting.
Let’s be real. It’s just a stationary bike, right? Technically, yes. But if you tell a hardcore enthusiast that spinning is just "sitting on a bike," they might actually fall off their clip-in cleats in shock. Developed in the 1980s by a guy named Johnny Goldberg (better known as Johnny G), it was originally a way for him to train for ultra-endurance races indoors. He wanted to mimic the road. He wanted the climb. He accidentally started a global phenomenon that turned into a multi-billion dollar industry.
Spinning What Is It and How Does It Differ From Normal Biking?
The biggest hurdle for beginners is usually the bike itself. These aren't your grandma's upright exercise bikes with the plush velvet seats and the built-in book racks. A spin bike uses a heavy weighted flywheel at the front. When you pedal, you’re building momentum in that wheel. Because it's a fixed gear, the pedals keep moving as long as the wheel is spinning. You can’t just stop pedaling and coast like you’re riding through a park. If you want to stop, you have to use the emergency brake or slowly let your legs decelerate. It’s intense.
Honestly, the "what is it" part of spinning is more about the atmosphere than the hardware. You’re in a dark room. The music is loud—sometimes concert-level loud. The instructor is essentially a DJ, a motivational speaker, and a drill sergeant rolled into one. You aren't just pedaling; you're following a choreographed routine. You’ll be told to turn a knob to add "road" (resistance), stand up out of the saddle to simulate a hill, or sprint like a dog is chasing you.
Research from groups like the American Council on Exercise (ACE) shows that a 45-minute session can burn anywhere from 400 to 600 calories. That’s why people do it. It’s efficient. It’s a high-intensity interval training (HIIT) session that doesn't involve the joint-jarring impact of running on pavement. Your knees will thank you, though your glutes might have some choice words for you the next morning.

The Equipment Barrier: Cleats, Padded Shorts, and Water
You don't need the fancy gear to start, but you'll want it eventually. Most studios use bikes that accommodate both regular sneakers (using cages) and cycling shoes (using clips). Those clips, usually SPD or Delta Look, lock your foot onto the pedal. This sounds terrifying to a newbie—the idea of being "stuck" to a machine—but it actually makes the workout safer. It allows you to pull up on the pedal as well as push down. This engages your hamstrings and makes your stroke much more efficient.
Then there’s the seat. Or the "saddle."
It’s small. It’s hard. It’s going to feel like you’re sitting on a brick for the first three classes. This is the part no one tells you: your body gets used to it. After about two weeks, the soreness goes away. In the meantime, some people buy padded cycling shorts. They look a bit like a diaper under your leggings, but they are a lifesaver. Don't be embarrassed. Everyone else in the room is either wearing them or wishing they were.
Understanding the Metrics: Watts, RPM, and Resistance
If you're at a high-end studio like SoulCycle or Flywheel (or using a Peloton at home), you'll see a screen. This is where the data nerds thrive.

- RPM (Revolutions Per Minute): This is your cadence. How fast are your legs moving? Most instructors will give you a range, like 60-80 for a heavy climb or 100-110 for a sprint.
- Resistance: Usually a knob between your legs. There’s no universal standard for "Level 10" resistance. Every bike is different. One bike’s 10 is another bike’s 20. You have to feel it out.
- Output/Watts: This is the big one. It’s the combination of how fast you’re going and how much resistance you have on. This measures the actual power you’re producing.
Why Your Brain Craves the Spin Room
There is a psychological component to spinning that you don't get from a treadmill. It’s the group dynamic. Psychology studies, including those on "social facilitation," suggest that humans work harder when they are in a group. When the lights go down and the beat drops, you find yourself pushing harder because the person next to you is pushing. It’s contagious.
Instructors often use "rhythm riding," where you move your body to the beat of the music. It’s almost like dancing. You’ll see people doing "tap-backs" (shifting their weight back over the saddle) or small push-ups on the handlebars. Purists will tell you this isn't "real" cycling. They aren't wrong; you’d never do a push-up on a road bike. But for the average person looking to burn fat and have fun, the "dancing" makes the time fly by. It turns a chore into an event.
Safety and Common Mistakes
Don't just walk in and start cranking the knob. The most common injury in spinning is actually to the lower back or knees, usually caused by a bad bike setup. If your seat is too low, your knees take the brunt of the force. If it's too high, your hips will rock back and forth, which wreaks havoc on your spine.
Pro tip: Ask the instructor to help you set up. Your seat should generally be at hip height when you're standing next to it. When you're on the bike, your leg should have a slight bend at the bottom of the stroke. Never lock your knees. Keep your core tight. If you find yourself leaning all your weight onto your wrists, you're doing it wrong. Your legs should be doing the work, not your arms.

Is It Just a Fad?
People have been calling spinning a fad since the 90s. Yet, here we are in 2026, and the industry is bigger than ever. We've seen the rise of boutique studios, the explosion of home-based streaming bikes, and now hybrid models where people do both. It isn't going anywhere because it solves the biggest problem with working out: boredom.
It's also incredibly inclusive. In a running group, the fast people are in the front and the slow people are in the back. In a spin class, everyone stays in the same room. You can have a pro-athlete and a beginner on side-by-side bikes. They both get a great workout because they control their own resistance. No one knows if your knob is turned to 5 or 50. You’re only competing against yourself.
Getting Started: A Checklist for Your First Ride
If you’re ready to stop asking "spinning what is it" and start actually doing it, here is the non-intimidating way to jump in.
- Arrive 15 minutes early. Seriously. You need time to adjust the bike and learn how the clips work.
- Bring a towel. You will sweat. A lot. More than you think is physically possible.
- Hydrate before, during, and after. Most spin bikes have two water bottle holders for a reason. Use them.
- Don't feel pressured to keep up. If the instructor says "turn it up" and your legs are screaming, just keep it where it is. It's your ride.
- Sit in the back. If you’re nervous, the back row lets you watch the "vets" in the front row to see how they move.
Spinning is essentially a high-energy escape. For 45 minutes, you aren't a parent, an employee, or a student. You’re just a person on a bike, moving to a beat, pushing through a metaphorical hill. It’s cathartic. It’s loud. It’s exhausting. And honestly, once those endorphins hit in the final sprint, you’ll probably be hooked.
To make the most of your first experience, search for local studios that offer a "New Rider" special. Many places will give you the first class for free or at a steep discount, often including the shoe rental. Before you go, check their website for "Bike Setup" videos so you have a head start on the mechanics. When you get there, tell the person at the front desk it's your first time—they'll make sure you don't end up struggling with your seat height alone in the dark. Focus on finding the rhythm first, and worry about the heavy resistance once your legs get their bearings after a few sessions.
