Even if you’ve packed on a few winter pounds, had kids, or neglected your belly for years, it’s never too late to get your middle section into a firm and sexy shape.

The following moves hit all of the major ab muscles, specifically the rectus abdominis (ie. the “six pack” muscle) and the obliques. They also force you to focus on your abs throughout the motion (no worries about sleep walking through this routine). Perform these exercises 3 times a week, in addition to your interval training routine.

Slide and Stride

Begin in plank position on a slick floor with hands shoulder-width apart, toes resting (FYI wear socks!). Draw your bellybutton toward your spine and keep your head and torso stationary as you slide your right knee toward your chest. Return to starting position and repeat with left leg to complete 1 rep. Do 10 reps. To make it harder, pull both knees in simultaneously, without lifting your hips.

Tuck Extension Drop

Lie faceup with your knees bent, feet flat and arms out in a T on the floor, palms down. Pull your bellybutton toward your spine. Tuck your knees into your chest and hold for 2 counts. Extend legs toward the ceiling and hold for 2 counts, then lower your legs 45 degrees in 4 counts. Return to starting position. Do 12 reps.

Pike 90 Crunch

Lie on your back with your bellybutton pulled in, extend your left leg slightly above the floor and raise your right leg toward the ceiling. Place your left arm behind your head and extend your right arm at your side, slightly off the floor. Lift and twist your torso to the right, reaching your left shoulder toward your right knee. Lower and do 12 reps, then switch arms and legs to complete set.
