Crisscross Crunches
Targets abs
An easier move to do in between more difficult reps, these crunches will give you incentive not to fall behind. Set a number and see if you can match your partner's pace to complete it.
- Sit on ground in crunch position, back flat on the floor, knees bent, abs engaged. Hands should be behind your head or crossed in front of your chest.
- Hook legs with partner, with your legs locked in between theirs. Crunch up, keeping abs engaged and hands not pulling on your neck or head if they are behind you.
- Complete 10 reps for 3 sets, or until fatigued
- Make it harder with bicycle crunches: Lie next to your partner, face up with right arm extended out to side, palm on ground, and left hand behind head. Lift left leg 6 inches off ground and bend right knee 90 degrees so shin is parallel to ground. Bring left shoulder toward right knee. Keeping left leg elevated and right knee bent, lower torso. Do 10 crunches. Lower legs. Switch sides; repeat.
