The 10-minute workout that will transform your abs

Time: 10 minutes

Equipment: Mat

Good for: Abs

Instructions: For each move, perform as many reps as possible in 45 seconds, then rest for 15 seconds. Continue to the next move. After you've completed all four moves, rest for one minute, then repeat the circuit. Complete two rounds total.

Tatiana Lampa, ACSM-certified personal trainer, says she uses this workout for clients who want to transform their abs—and they see serious results. Lampa recommends doing this routine three times a week for max results.

V-up

How to: Lie face-up on the floor with your legs and arms straight. In one movement, lift your torso and legs as if you're trying to touch your toes. Lower your body back down. That's one rep. Perform as many reps as possible in 45 seconds, then rest for 15 seconds.

Reverse crunch

How to: Lie on the floor with your legs up and slightly bent, hands at your sides with palms faced down. Brace your torso by contracting your abs. Lift your hips up, hold for a second, then release down to the start position, keeping your legs in the air. That’s one rep. Perform as many reps as possible in 45 seconds, then rest for 15 seconds.

Around the world

How to: Lie on your back with your legs extended straight up into the air. Engage your core and draw a circle, to the right, with your legs. Continue for 45 seconds, with 15 seconds of rest.

Repeat on the left side for 45 seconds, followed by 15 seconds of rest.

Plank-up

How to: Place your forearms on the floor, elbows under your shoulders, and extend your legs behind you. Keeping your back flat, straighten your right arm and place your palm flat on the floor, directly under your shoulder, then repeat with your left arm so you're in a pushup position. Reverse the movement, lowering back onto your right forearm and then onto your left, to return to start. That's one rep. Perform as many reps as possible in 45 seconds. Take one minute of rest before repeating the circuit.
