The pills like oxyelite or mytotrpin only really work in parallel with exercise and diet, so i guess no is an appropriate answer? and intense exercise is really the best way to do it, interval training, tabata cardio, lots of redline stuff. Ive lost almost 80 lbs in a year and have injured both shoulders, so i kinda understand your situation. Biking is a great tool though, read about tabata drills and do them on the exercise bike! best 5 minute workout youll do. Then you can always do a good warm up/cool down on while still on the bike
