Your abs aren't the only part of your core. Here's a Locust variation to strengthen your entire back.
- Lie on your belly, extending your arms straight in front of you.
- Inhale to lift your legs, head, and upper body off the floor. As you breathe, extend the crown of your head away from your toes, lengthening as much as you can through your spine. Keep your shoulders relaxed and lift your arms and legs as high as possible.
- Stay for five breaths and then release back to the mat.
