This Is Exactly How Selena Gomez's Trainer Likes to Sculpt Abs

Updated on 5/10/2018 at 2:40 PM

We recently caught up with celeb trainer extraordinaire Amy Rosoff Davis — the mastermind behind Selena Gomez's fitness routine (particularly during her Revival tour). As one of the fitness geniuses behind some of Hollywood's strongest women, we had one very important question to ask Amy: what's your go-to ab move?

"You can't go wrong with a plank," Amy told POPSUGAR. "There are so many different plank moves — mountain climbers, pikes, single-leg, elbows to hands . . . there are tons of variations!" And the best part about planks is that they don't just give you lean, ripped abs. "If you get your form right, they work the entire body," she said.

Ahead are over 30 incredible body-torchin', ab-sculpting moves that'll have you feeling strong, powerful, and confident.

Plank

Start resting on all fours.
With your palms flat, raise up off your knees onto your toes. Keep your hands directly below your shoulders.
Contract your abs to keep yourself up and prevent your bottom from sticking up. Remember to keep your belly button pulled in.
With your head and spine in line, keep your back flat — don't let it curve. Picture your body as a long, straight board.

Modified Plank on Knees

Start an all fours and walk your hands forward until your body forms a straight line from your head to your knees. Keep your abs lifting away from the floor and do not allow your pelvis to sag.
Lift your feet toward your butt to engage your hamstrings and glutes.

Elbow Plank

Start on the floor, resting on your forearms and knees.
Step your feet out one at a time, coming back into plank position.
Contract your abs to prevent your booty from sticking up or sinking. Your spine should be parallel to the floor with your abs pulling toward the ceiling.

Keeping your core strong and your body still, use your arms to roll the ball in small counterclockwise circles in each direction.

Plank With Lateral Arm Reach

Start in a plank position.
