Knee Tuck

Pro Tip

To make the movement more difficult, you can keep your feet raised in between reps, keeping them from touching the ground.

How To

Lie supine on the ground with your legs bent, arms by your sides, and head firmly planted on the ground.
Exhale and raise your knees towards your face while keeping your legs bent, allowing your butt and lower back to leave the ground.
Continue to raise your legs until you can no longer do so while still keeping your upper back on the ground.
Inhale and lower your legs to the ground, returning to the starting position.
