After having owned many infommercial fitness products, I finally found one that is easy to use and performs just like on the commercial. The Body by Jake Gravity Force Trainer is a wonderful piece of exercise equipment. It has 7 basic exercises that workout the entire body in just 20 minutes. You just sit on the large cushioned seat and adjust the steel pins to the weight that suits you. It comes with an instructional DVD that shows you just what to do. It suggests lighter weight and more repetition for women and fewer reps with heavier weight for men. I like the fact that one piece of equipment is just right for both my husband and myself. After trying the Gravity Force Trainer, my husband quickly got rid of his bench and free weights. Not only can you workout your arms, legs and back but you can also do situps and crunches. It is so simple to switch from each exercise that my teenager and pre-teen have been able to do light reps on it themselves. The only downfall is its size, it's quite large and bulky. We keep it in the garage because it's quite an eyesore.
