BodyTogs are weighted "sleeves" worn under clothing on the calves and forearms to increase the weight load. A full set of arm and leg BodyTogs adds from six to seven pounds of weight, depending on size. These extra pounds automatically increase the calories you burn throughout the day. Whatever you do - from walking the dog to cleaning the house or climbing stairs - BodyTogs turns it into a calorie-burning workout. BodyTogs feature an innovative "no-show" design that fits snugly and comfortably under loose clothing. You can wear them everywhere - and no one needs to know.
