Hey to all of the ladies that responded ,..thank you so much for your advice. I began working out again and ..I realized that working out is helpful toward making me feel better....I am just curious..what are your opinions on Trim Spa? Do you think this works well with an exercise program?...And is it true that you must do at least 30 min of cardio on the same machine..otherwsie switching machines can lesson the effects of cardio??..just curious since i just started....
