Tony, I am a 56 yr. old man. I'm 5'8" and was very overweight. My daughter, started doing your tapes and Ab Isolator and she lost 102 lb. So I also started doing the Ab. It has taken me 9-10 months to lose this weight. My daughter and I jog everyday at 4:30 a.m. I feel very good about myself and I still want to lose about 50 lb. That will leave me weighing 147 lb. Thanks, John
