The most common excuse that people make to get rid of exercise is lack of time. Strangely enough, those same people have got enough time to chat with friends for hours or watch their favorite TV program while sitting on the couch.
The second excuse is that of money, and third one is of compatibility of the exercise equipment. Sure, not every type of exercise equipment suits every type of body, and hey, you are here to workout, not breaking your bones and ribs, are you?
