Hi MFT, hows it going, I was wondering if the products from t.v. that advertise ab rocket, bowflex gym, bowflex dumbells, red, and etc really work or is that just a way to convince consumers to buy their products. I was thinking of getting the bowflex dumbells but I'm not sure if it's worth it because their expensive online, but it has about 20 diferent pundages you can change. I have 20 lb and 50 lb dumbells but their certain exercises I still can't do because I need heavier wieght or lighter weight. What do you think I should do?
