RPM — Revolutions Per Minute — is the globally recognized Les Mills indoor cycling program that has transformed the way people think about cardio training. Unlike solitary sessions on a stationary bike, RPM is a group experience set to a carefully constructed music journey that takes participants through simulated outdoor terrain: flat sprints, climbing hills, and interval surges. The result is a workout that feels far shorter than it is, produces significant calorie burn, and delivers lasting fitness gains — all without a single footstep on the ground.
How RPM works
RPM is practiced on specially designed stationary bikes with a weighted flywheel and manual resistance control. Each participant can adjust the resistance dial on their own bike, meaning the class simultaneously accommodates complete beginners and highly trained athletes. The instructor provides guidance — "increase resistance two turns", "aim for 90 to 100 RPM" — but each rider calibrates to their own capacity and perception of effort.
A full RPM session lasts 45 to 55 minutes and is divided into multiple tracks, each simulating a different riding condition. A warm-up track brings the body to working temperature and introduces the fundamental pedaling positions. Speed tracks train fast-twitch muscle fibres and cardiovascular responsiveness. Hill tracks build leg strength and aerobic power through sustained high resistance. Interval tracks develop anaerobic capacity and mental toughness through repeated high-effort surges.
The music is central to the RPM experience. Les Mills designs specific playlists for each release, with tempo, energy, and emotional arc precisely matched to the physical demands of each track. The music guides pedaling cadence instinctively, making high-effort phases feel more manageable and the overall session more enjoyable.
Cardiovascular and muscle benefits
Regular RPM training produces a comprehensive set of fitness adaptations:
- Cardiovascular efficiency: The sustained aerobic demand of RPM significantly improves heart and lung capacity, reducing resting heart rate and improving the body's ability to deliver oxygen to working muscles.
- Lower body strengthening: High-resistance pedaling intensely works the quadriceps, hamstrings, glutes, and calves. After several weeks of consistent practice, the legs become noticeably stronger and more defined.
- Calorie burn: An RPM session burns between 400 and 700 kilocalories depending on body weight and effort level, making it highly effective for weight management when combined with appropriate nutrition.
- Zero joint impact: The cycling motion is smooth and continuous — there is no landing force, no rotational stress, and no shear on the knee or hip joints that characterizes many other cardio formats. This makes RPM an excellent option for people managing joint sensitivities or returning from lower-limb injuries.
- Endurance base: The aerobic conditioning built through RPM transfers to other sports and activities, improving performance and reducing fatigue in everything from hiking to recreational sport.

RPM is one of the most inclusive group fitness formats available. Its self-paced nature means that a beginner and an elite cyclist can train side by side in the same class without either feeling out of place. The following groups find RPM particularly well suited to their needs:
- People returning to exercise after a break, injury, or surgery who need low-impact cardio
- Runners and team sport athletes who want cross-training that builds fitness without adding running volume
- Seniors seeking an effective cardiovascular workout that is safe for ageing joints
- Anyone who finds traditional cardio machines monotonous and needs the motivation of music and a group environment
- People managing knee pain, hip problems, or lower back issues who cannot tolerate high-impact exercise
Before the first session, proper bike setup is essential. Seat height, fore-aft saddle position, and handlebar height all affect both performance and injury risk. Hamza always takes time before class to help new participants set up their bikes correctly — a detail that makes an immediate and lasting difference to the experience.
An RPM session with Hamza Fatil
Hamza Fatil is a certified Les Mills RPM instructor with years of experience coaching group cycling in Marrakech. His classes are known for the quality of his cueing — clear, timely instructions that allow everyone to follow the structure of the session without confusion — and for his ability to create a motivating atmosphere that pushes participants to their best without ever feeling coercive.
Each class follows the official Les Mills release structure, ensuring the programming meets international standards for safety and effectiveness. Hamza adapts his coaching emphasis based on the group composition — more technique-focused instruction when newer participants are present, more challenge and intensity variation for experienced riders.
For clients integrating RPM into a broader training program, Hamza recommends pairing it with strength-focused sessions such as BodyPump to address the muscle groups that cycling does not train — the upper body and core — for a genuinely balanced fitness outcome.
