Start moving. "Don't worry about weights, just get up and walk or try something fun like Zumba," McCall said. Start with a form of cardio, such as walking, spinning or using a cardio machine. Adopt a good core-building activity, such a Pilates or use TRX to build a baseline of strength. Holland recommends exercise DVDs. "They're ridiculously inexpensive now, you don't have to leave home to exercise and you can find everything from tai chi to P90X," he said. "And, if you press play enough, they really work."
