Having twins doesn't stop Rebecca and Jerry from finding time to work out together. Fitness cover girl Rebecca shared that the couple loves to tandem bike around the hills near their home, and aren't afraid to get competitive. "Jerry is very show-offy when he's good at something, and he's pretty much good at everything," she said. "But he's been doing Bikram yoga for about a year now, and he isn't very flexible. I'm happy there's one thing I'm better at than he is."
