Alternating Cross Body Crunch (Bodyweight)

Also known as: Alternating Cross Body Crunch (Bodyweight).

Alternating cross-body crunch from a feet-planted bent-knee start: one knee rises toward the opposite shoulder, then that foot returns to the floor.

How to perform this exercise

1. Lie on your back with both knees bent and both feet flat, hands lightly beside the head and elbows open.
2. Raise the right knee and curl the left shoulder diagonally toward it while the left foot remains planted.
3. Return the shoulders and right foot under control to the starting position without pulling the neck.
4. Repeat with the left knee and right shoulder, alternating steadily.
