This is an anterior core stability exercise that will help prevent excessive arching of the lumbar spine. Adding the knee drop to the plank will force you to stabilize your core more.
- Start resting on all fours.
- With your palms flat, raise up off your knees onto your toes. Keep your hands directly below your shoulders.
- Contract your abs to keep yourself up and prevent your bottom from sticking up. Remember to keep your belly button pulled in.
- With your head and spine in line, keep your back flat — don't let it curve. Picture your body as a long, straight board.
- With control, slowly tap your left knee to the ground without moving your hips. Lift your left knee back up, returning to the starting position. Repeat the same movement with the right leg. This completes one rep.
