What Is Indoor Cycling? How Spin Classes Work in Gyms and Studios
Indoor cycling is one of the most successful and widely adopted group fitness programs in modern gyms, health clubs, recreation centers, and boutique studios. Often referred to as a “spin class,” indoor cycling involves riders pedaling stationary bikes while an instructor leads structured intervals, climbs, and endurance segments set to music.
Unlike many other cardio workouts, indoor cycling allows riders of different fitness levels to train together in the same class. Each rider controls their resistance and cadence, making the workout scalable for beginners, experienced athletes, and everyone in between.
At Indoor Cycle Pros, we work directly with fitness facilities across the United States that rely on commercial indoor cycling bikes to power their group cycling programs. This guide explains how indoor cycling works, why spin classes are so popular, and how gyms and studios structure successful cycling programs.
The Rise of Indoor Cycling Studios
Indoor cycling first gained popularity in the late 1980s when instructor-led cycling workouts were introduced as a structured group training format. Over the following decades, spin classes evolved from a niche workout into one of the most recognized group fitness experiences in gyms and boutique studios.
Today, indoor cycling programs can be found in:
- boutique cycling studios
- full-service health clubs
- university recreation centers
- corporate wellness facilities
- resort fitness centers
- community recreation centers
These programs remain popular because they combine cardiovascular training, motivating group energy, and highly efficient class formats.
How Spin Classes Work
A spin class typically takes place in a dedicated cycling studio filled with commercial indoor cycling bikes. Riders follow an instructor who guides the class through different riding segments designed to simulate outdoor cycling conditions.
A typical class may include:
- warm-up intervals
- seated endurance riding
- standing climbs
- high-cadence sprint efforts
- recovery segments
- cool-down and stretching
The instructor controls the class structure while riders adjust resistance on their individual bikes to match the intensity of the workout.
This flexible format allows a room full of riders to participate together while still maintaining personalized training intensity.
Why Gyms and Studios Offer Indoor Cycling
Indoor cycling classes remain one of the most reliable group fitness formats for gyms and studios. They attract a wide range of members and allow facilities to deliver structured workouts in a highly efficient environment.
Many facilities invest in cycling programs because they provide:
- high member participation
- strong group energy and motivation
- low-impact cardiovascular training
- scalable workouts for different fitness levels
- repeatable class formats that instructors can easily program
This combination of accessibility and intensity makes indoor cycling one of the most consistent drivers of group fitness participation.
Indoor Cycling vs Outdoor Cycling
While outdoor cycling offers its own benefits, indoor cycling provides a controlled training environment that many riders find more consistent and accessible.
Indoor cycling removes many external variables that can affect outdoor rides, including weather conditions, traffic, road hazards, and inconsistent terrain.
Inside a studio environment, riders can:
- train year-round regardless of weather
- follow structured interval programming
- track cadence and performance metrics
- maintain consistent workout intensity
For these reasons, many cyclists use indoor cycling classes as a reliable way to maintain conditioning throughout the year.
Commercial Indoor Cycling Bikes Explained
The quality of the bikes used in a spin class plays a major role in the overall rider experience. Fitness facilities typically rely on commercial indoor cycling bikes designed for multiple daily classes and long-term durability.
Unlike residential exercise bikes, commercial cycling bikes are built to withstand heavy use in high-energy studio environments.
Many facilities choose the Stages SC2 Indoor Bike because it offers commercial-grade durability, smooth magnetic resistance, and a consistent ride feel across an entire bike fleet.
Facilities looking for advanced performance metrics often upgrade to the Stages SC3 Indoor Bike, which integrates power measurement technology to provide real-time rider performance data.
Why Rider Connection to the Bike Matters
Another important part of the indoor cycling experience is how the rider connects to the bike. Many studios use clip-in cycling pedals that allow riders to secure their cycling shoes directly to the pedal.
This connection helps riders maintain smoother pedal strokes, better power transfer, and improved stability during standing climbs and high-intensity efforts.
Many facilities choose professional-grade indoor cycling pedals that support common cycling cleat systems used in studio environments.
A properly fitted bike combined with a secure pedal connection can significantly enhance the indoor cycling experience.

Fitness facilities planning to launch or expand an indoor cycling program should consider several key factors.
These include:
