I was wondering there is anything to strength certain areas..not really spot reduce just help. Have a flab of skin between my arm and my chest that presses together to make a roll. I was hoping anyone might have an idea on how to help. Also all of my extra weight seems to go to my low back. I do cardio 4 times a week and stregth training about 3 times a week for about an hour..should I increase this or change it?
