At last, the secret to first lady Michelle Obama's sculpted arms? Tricep pushdowns and hammer curls. So says Cornell McClellan, Obama's longtime personal trainer, who described the workout routine of his famous client in the October issue of Women's Health magazine. She began working with McClellan in 1997 at his Chicago fitness studio. McClellan said that at the end of an intense routine of cardio workouts and weight training, Obama finishes with the “arm-shaping superset” of tricep pushdowns and hammer curls to tone one of the most commented-upon pair of arms in the world. She often wears sleeveless outfits. How to get arms like Michelle Obama's? Perform one set of tricep pushdowns using a straight bar attached to the high pulley of a cable station and then, without resting, follow with a set of hammer curls using dumbbells. Immediately repeat the entire process until two or three sets of both exercises have been completed. The details of Obama's fitness routine came as part of a series of interviews by President Barack Obama and Michelle Obama on health care and their personal fitness and nutrition habits. Obama was interviewed by Men's Health; Michelle Obama gave her first interviews to Women's Health and Children's Health, a new magazine by Rodale Inc., publisher of the men's and women's health magazines.
