Spinning is an intensive cycling workout on a spinning bike with a heavy flywheel that is linked to the pedals. The intensity varies due to different body positions (e.g. standing and sitting), pedal speed and resistance. Your legs move constantly, which means that every second of the available time is put to good use. Using a specific app, training is focused on heart rate and resistance. This provides insight into training results and progression of fitness. Spinning is suitable for all ages and fitness levels.
