Engage your core so that your lower back gently presses against the floor.

Using your abs, roll your body up until you are sitting upright with your back straight.

Work to keep your elbows parallel to your bodydont let your elbows wing out.

Keeping yourself supported with your hands, straighten both arms to push back up.

Repeat, keeping your core tight throughout and weight in your arms.

Duck Walk to Stand

Stand with your feet hip-width apart and core engaged.

From this squat position, step your right foot forward, then your left foot forward.

Continue to repeat this pattern, squatting and walking forward to stand.

Then squat and walk backward to stand.

At the halfway point, switch the foot you typically lead with.

Again, verify to keep your hips level and do not allow your torso to twist.

Continue to alternate hand taps, keeping your core engaged and your hips as steady as possible.
