Men's Health Guide to Peak Conditioning

This one’s tough--But it really sculpts your abs!

HANGING KNEE RAISE CROSSOVERS:
Start by hanging fully extended from a chin-up bar with your hands a little wider than shoulder-width apart. Your palms should be facing outward and your feet lightly touching the ground. Now, keeping your legs together, slowly lift your knees up toward your left shoulder as high as you can. Slightly thrust your pelvis forward, but don’t rock or sway for momentum. Hold for a second at the top, then lower and repeat to your right side. Don’t rest between reps. Keep your abs tight.

For an even tougher variation, lift your legs instead of just your knees, keep your feet together, and lift toward your left shoulder as high as you can. You’ll need to slightly tilt your pelvis forward. Lower, then repeat on your right side.
