Oblique Crunches with Hand Touches
Lie face up with knees slightly bent and heels on the floor. Your partner sits with knees on either side of your feet, facing you. Bend your arms, tucking your elbows into your body with your hands held close to your chest. Your partner raises his palms to face you.
Curl your torso upward to face your partner, lifting your head and shoulders off the floor. Twist slightly to your left as you reach across to touch your partner’s right hand with your right hand. Then twist to the right, touching your partner’s left hand with your left hand. Return to starting position.
Repeat for 12-15 reps, twisting to your left (touching right hand to partner’s right hand first) and another 12-15 reps twisting to your right (touching left hand to partner’s left hand first); switch positions with your partner.
