Lying Alternate Heel Touches.

Make every rep count.

1. 01

   Lie on your back with knees bent and feet flat. Reach your arms long by your sides toward your heels.

2. 02

   Brace your core, then exhale sharply as you lift your shoulders slightly off the floor and slide one hand toward the base of the same-side heel.

3. 03

   Keep your neck relaxed (chin slightly tucked) and avoid yanking with your shoulders—let your obliques/abs do the work.

4. 04

   Inhale as you return to center with control, then reach to the other heel.

5. 05

   Continue alternating sides for the prescribed reps, keeping your lower back gently pressed into the floor.
