Jealous of Robert Pattinson's chiseled six-pack? It's okay to admit it -- even some of his female fans are. So we spoke to the man behind the physique, celeb trainer and fitness maven Harley Pasternak, to find out the moves Pattinson uses on his enviable core.
Pasternak recommends starting with a five-minute cardio warmup, then heading into the circuit. "To start, three sets of 20 to 25 reps per move is great, but remember to keep changing your program week to week to keep seeing results," he advises.
1. Bicycle Crunch: Lay flat on your back and raise your legs into the air, bending them at a 90-degree angle. Crunch your head up with your hands interlaced behind your head. Bend your right knee towards your left elbow, extending your left leg, then repeat, switching sides. "This move is great because it trains the ab muscles forwards, backwards and sideways on the transverse muscle," says Pasternak.
2. Dumbbell Side Bend: Stand up straight with a dumbbell in your right hand and your left hand on your hip. Lean down with your weighted hand, moving the dumbbell towards your knee, and then return to standing. Do all reps on one side, then switch. "This tones the obliques and helps create that crease you see on Rob. It's great for those shirtless scenes!" he says.
3. Double Crunch: Lie flat on your back with your knees bent and your feet flat on the floor. Bring your chest up, as you do in a regular crunch, and simultaneously roll your knees in towards your chest. "It should look like an oyster closing up," says Pasternak.
4. Superman: Lie flat on your stomach, with your arms straight forward in front of you and your legs straight back. In one fluid motion, raise your arms and legs as high as you can upwards. "It trains every single muscle in your midsection," says Pasternak.
