My Abs Have Never Screamed Louder Than After Jordan Chiles’s and Simone Biles’s Core Workout

• Begin on your back with your legs straight and your arms extended overhead.
• Actively press your lower back into the floor, and draw your belly button into your spine.
• Inhale to slowly lift your arms and legs off the floor. Keep your hands and heels as low to the ground as possible, while still pressing your lower back into the floor.
• Simultaneously lift your arms and legs a few more inches toward the ceiling without lifting your shoulders (you’re not reaching your hands to your feet like in a V-up), then lower back to your hollow position.
• This is a pulsing motion, and you should maintain tight abs the entire time.
• Complete 20 reps.

• Begin on your back with your legs straight and your arms extended overhead.
• Actively press your lower back into the floor, and draw your belly button into your spine.
• Inhale to slowly lift your shoulders, arms, and legs off the floor. Keep your hands and heels as low to the ground as possible, while still pressing your lower back into the floor.

• Hold this position for five seconds.

• Lie face up with your arms overhead and your legs extended, resting on the floor.
• Lift your hands and feet a few inches off of the floor into a hollow position, and keep your abs engaged by pulling your belly button into your spine and pressing your lower back into the floor.
• With control, lift your upper body and lower body simultaneously, reaching your arms toward your feet.
• Lower your arms and legs toward the floor to complete one rep. The more you bring your upper back off of the ground during the “V” part of the exercise and the lower you bring your arms and legs at the end of each rep, the harder the move will be.
• Do 20 reps.

• Begin on your back with your legs straight and your arms extended overhead.
• Actively press your lower back into the floor, and draw your belly button into your spine.

• Lie face down on your stomach with your arms and your legs extended. Keep your neck in a neutral position.
• Keeping your arms and legs straight (but not locked) and torso stationary, simultaneously lift your arms and legs up slightly off the floor.
• Lower back down to complete one rep. This is less movement than a full-motion Superman lift (think of the movement as pulsing up and down).
• Do 20 reps.

• Lie on your belly, and extend your arms straight out in front of you.
• Pull your belly button into your spine.
• Lift your legs, arms, and chest off of the floor, squeezing your glutes and legs as you do and keeping your arms by your ears.

• Lie flat on your back. Extend your arms so they’re against the sides of your body with your palms pressing into the floor, or bend your elbows and place your palms under the back of your head. Bend your knees, and draw them into your ribs. This will make it easier to pull your navel in toward your spine and actively press your lower back flat on the ground.
• Lift both legs straight up toward the ceiling, continuing to engage your abs and pressing your lower back into the ground.
• Keeping your core strong, slowly lower your right leg down toward the ground until it is a few inches above it. Slowly scissor your legs, lifting your right leg back up as you lower your left leg down toward the ground.
• Repeat this move for a total of 20 reps.

• Lie face down on your stomach with your arms and your legs extended. Keep your neck in a neutral position.

• Lower your arms and legs toward the floor with control back into a hollow position to complete one rep.

• Lower your arms and legs toward the floor to complete one rep. If the “super” part of this move is too hard, do a normal V-up.
• Complete 15 reps.

• Lie on your side with your arms and your legs extended. Bring your feet slightly in front of you so that you’re in a hollow position. You can put one hand down for support if you need (as seen here).
• While keeping your navel pulled into your spine, simultaneously lift your arm(s) and legs a few inches toward the ceiling. This is a pulsing movement, so you don’t have to lift as high as what’s shown here if that’s too much for you.
• Lower back down, but not completely, so there’s a bit of space between your legs and arms and the floor.
• Complete 20 reps.
• Move on to side hollow hold on the same side.

• Lie on your side with your arms and your legs extended. Bring your feet slightly in front of you so you’re in a hollow position.
• While keeping your navel pulled into your spine, simultaneously lift your arm(s) and legs a few inches toward the ceiling. Engage your core as you hold this position for five seconds before lowering back down.
• Shown here are two options for holding your side hollow hold. You can put one hand down for support – like the side hollow pulses – or you can lift from your core without putting a hand down.
• Move on to side hollow rock on the same side.

Complete all three of these side hollow moves on each side.

• Lie face down on your stomach with your arms and legs extended. Keep your neck in a neutral position.
• Place your hands by your ears with your elbows out wide. Lift your upper body toward the ceiling (several inches off the floor). Only lift as far as your back can allow; don’t push it.

This circuit should be done without stopping, moving through a Superman with different arm positions demonstrated here:

• Hold 10 seconds of a regular Superman with your arms and legs out long, followed by 10 reps of rocking back and forth.
• Hold 10 seconds of a Superman with your hands by your ears and elbows out wide, followed by 10 reps of rocking back and forth.
• Hold 10 seconds of a Superman with your arms raised behind you and against your sides, followed by 10 reps of rocking back and forth.

The above video shows a modified version, where your feet are not lifted, only your chest.

This circuit should be done without stopping, moving through a hollow hold with different arm positions demonstrated here:

Repeat this two more times.
