- Begin in plank position with your hands underneath your shoulders, body in one straight line.
- Keeping your core engaged, cross your right hand over your left as you step your left foot to the left.
- Then, simultaneously, step your left hand and right foot to the left, so you're back in plank position. Your hands move together as your feet step apart, keeping your obliques long.
- Repeat this for five steps to the left and five steps to the right. Be sure to keep your hips in line with your ribs as you move, drawing your navel toward your spine.
- This completes one rep.
Tip: To add more upper-body work to this exercise, add a push-up once you've completed five steps to the left and another push-up after your five steps to the right.
