Warrior crunch

This crunch variation works your core and lower body, including your thighs, glutes, and quads.

1. Stand with your feet slightly wider than shoulder width and your toes turned outward. Put your hands behind your head and open your chest.
2. Tighten your core and glutes. Bend your knees until your thighs are parallel to the floor.
3. Bend your torso to the side, moving your right elbow toward your right thigh. Repeat on the left side.
4. Start with 1 set of 8 to 12 reps.
