Leg lift crawl

This exercise strengthens your back and abdomen muscles.

1. Kneeling on hands and knees, place your hands directly under your shoulders and straighten your arms.
2. Lift your left knee and point it toward your elbow, while lowering your chin toward your chest.
3. Slowly extend your leg behind you without completely straightening it, while raising your head to look in front of you. Avoid arching your back.
4. Do left and right lifts 5 to 10 times each.
