Being covered up in Winter sweaters and Wellies is no excuse to skip a workout. If you overindulged a little too much this holiday season, now's the time to get back on track. This full-body workout will target all your major muscle groups, and it doesn't even require you to make a trip to the gym or go outside. Make some open space in your living room, use a set of cans as your weights, and work your way toward greater strength and a fitter bod. Spring break will be here sooner than you realize . . .
