- Start by lying on your back. Lift your legs into a "tabletop" position: with your knees directly above your hips and feet directly out from your knees, bent in a 90-degree angle with your shins parallel to the floor.
- Interlace your fingers and place your hands behind your head, with your elbows pointed out to the sides.
- Inhale to prepare, and as you exhale, peel the back of your head, the back of your neck, and finally the backs of your shoulders blades off the floor. Keep a ping pong ball-sized distance between your chin and chest and keep your elbows wide. Inhale to lower back down with control.
- Repeat 20 times.
- "Keep your legs still the whole time. This will wake up your deep abdominal muscles, your transverse abdominis, as well as your rectus abdominis — the long six-pack muscle," Jetter says.
