In the Elevators position (step 1), place one hand under your ribs and one below your navel [shown]. Inhale, expanding your belly out to the first floor, then exhale to bring the transverse to the third floor, keeping your shoulders still; this is the starting position.
Count out loud as you bring the transverse back to the fifth floor. Squeeze and hold there, bringing your ribs together. (This is 1 repetition.) Bring the transverse back to the third floor and repeat. Work up
to 100 reps 3–5 times per day.
To progress: After 2 weeks, you can work from the fourth to fifth floor and then from the fifth to sixth floor.
Benefit: Strengthens abdominals, especially the transverse.
