An indoor trainer is one that holds the bike stationary. It allows individuals to train indoors by pedaling at various resistance levels.
Trainers are of various kinds, ranging from basic ones with wheels to sophisticated smart trainers which transmit power data to apps. Trainers assist in structured workouts—such as intervals, cadence drills, and virtual group rides—regardless of the weather and hour. A mat on the floor below the trainer shields the floor from moisture, is less noisy, and makes everything stable. Indoor trainers are employed by road cyclists and triathletes for standard, controlled training during cold or recovery seasons when outdoor cycling is impracticable.
