For the next 60 seconds, the goal is to do as many crunches as possible while maintaining proper form. Keep your arms soft, so they're not pulling on the back or side of your head.
- Sit on your mat and bend your knees, planting your feet on the floor. Put your palms behind your ears.
- As you exhale, pull your abs in and lift your upper body. Inhale as you lower back down.
- Keep your chin down to keep your neck from straining, and make sure your ribs are aligned with your hips.
- Do as many reps as you can in 60 seconds.
