Jessica Chastain: Secrets of an A-list body

Actress Jessica Chastain chose an outfit that nipped in her slim waist on the red carpet recently. 

The 46-year-old actress maintains her slender physique with regular yoga and dance classes. 

She has said exercise inspires her: ‘It’s a reminder — especially when you’re holding a plank position, shaking and thinking, “I can’t do it!” — that you can get through anything.’

WHAT TO TRY: The side plank. A variation on the regular plank, this move will target the oblique abdominal muscles that wrap around the sides of your waist like a corset. 

Start in a plank position with your hands and arms up to the elbow straight and flat on the floor, and your body taut. 

Slowly lift one hand off the floor, out to the side and into the air, rotating your chest, body and legs 90 degrees with it. 

Hold for a count of five and return to the traditional plank, then repeat on the other side. 

Repeat three times on each side.
