The wattage required for indoor cycling depends on the type of training you are doing and your fitness level. Generally, a beginner cyclist should aim for an average power output of around 50-100 watts during their workouts. As your fitness level increases, you can gradually increase the wattage to challenge yourself further.
For more intense sessions, such as intervals or sprints, you may need to reach up to 300-400 watts or even higher, depending on your goals. Ultimately, finding a wattage that challenges you without overstraining yourself is essential.
