I have a roommate who is a serious fitness workaholic. Her everyday
routine includes doing aerobics and fitness videos for about 2 hours. In addition to her "regular" routine she also uses a thighmaster or
buttmaster everyday for 2 hours. Although my roommate gets tired and sore after working out amazingly she has enough energy the next day to do it all over again. I know exercise is suppose to be good but this seems like too much.
My 1st. question is my roommate doing more harm then good to herself?
2nd question can prolonged long term use of a thighmaster or
buttmaster cause injury?
