OUNCE AWAY PAIN
Mini rebounders that fit inside your bedroom provide a great aerobic workout for all levels of fitness and ages, though older people will need to do gentler, less gymnastic moves. Rebounding protects joints from hard-impact exercise and offers relief from neck and back pains. It also strengthens leg muscles and increases oxygen availability throughout the body.
NO WATER NEEDED
The advantage of a rowing machine is that it offers an all-over workout with very little impact on joints. Vigorous rowing is one of the most effective calorie-burning exercises, but you can set your own pace, and it will tone up flabby arms and help give you a flatter stomach.
