Would riding on a Stationary Bicycle help?
That’s rather a snide response. A stationary bike can be used to improve your fitness in a number of ways. Depending on what aspect of fitness you want to improve, you can use different programmes. For example: if you want to improve general aerobic stamina, you can exercise continuously at a moderate intensity (say, for 30 – 60 minutes). Or if you want to focus on speed, you can try the interval training that coachgary suggested. Cycling does improve general leg strength; but if you’re looking to increase your muscle size, an exercise involving heavier resistance would be more effective (say, weighted squats or the leg press machine). Ideally, your fitness programme would include a significant element of on-court work too (helping you to get badminton-specific fitness).
