Bethenny Frankel is a busy business woman, and she's also a busy mom. That means that she has to squeeze in a workout when she can, so popping in a workout DVD at home is the perfect solution. "At home, I do my own yoga DVD. A long time ago I used to be able to go to a gym or a yoga class, but that involves getting there, 20 minutes, getting back, 20 minutes," she recently told us. "I don’t have that extra time, so I really believe in at-home workouts."
