A-LIST BODY

HOW to get the enviable physiques of the stars. This week: Janet Jackson’s shoulders AT 51, singer and mother-of-one Janet Jackson recently showed off impressively toned shoulders in a black gown at an LA party — the result of intense workouts that focus on weight training.

WHAT TO TRY: The shouldertoning push and press. Stand holding a weight in each hand. Bend your elbows and lift the weights to just outside your shoulders, palms facing your body, with feet shoulderwidth apart and knees slightly bent.

Flex your knees, then energetically push up as you lift the weights above your head. Lower back to the start.

Do 12 repetitions and three sets.
