Why it made the list: Yes, a leg exercise made the top 10 list for abs. Anyone who has ever pushed their potential in the squat knows exactly why! Sure, squat variations work the legs and lower back, but they also crush the abs. Both front and back squats force your abs and spinal erectors to work overtime to maintain a neutral, upright position. If both were not firing at high rates, you'd fold under the weight or drop in a split second.
Kneel on a mat on all fours with your hands directly under your shoulders. Stretch your legs back one at a time to come into plank position (the “up” part of a push-up); engage your ab muscles. Your body should be long and straight; don’t let your hips sag or lift your butt too high. Imagine there’s a seat belt tightening around your waist, drawing your lower-ab muscles inward.
Start by placing your heels on a low bench and holding two light dumbbells (begin with 3 pounds). Place a rolled-up towel under your lower back to increase the range of motion of your upper abs. Point your toes. From this start position, raise your upper body to the position shown in the second photo. Breathe normally. Now press the weights overhead. Keeping your arms straight, press your heels hard into the bench, then lower your upper body and allow the weights to arc behind your head.
To do it: Start with feet in a wide stance, knees bent, arms up on guard. Keeping your lower body still, quickly lean your upper body to the right, then come back through the center and lean to the left. Repeat lean back to the right. Next, lower your upper body, from the right around to the left side, making a half circle with your torso. Return to start position. That’s one rep. (Tip: it helps to keep a steady rhythm with this move, think—or say aloud—1, 2, 3, weave to help you keep your tempo). Repeat 10 times total, alternating starting on the right and left sides.
Eat carbs. "There's this notion that carbs are bad and that you need crazy amounts of protein to be lean and fit," says Alcantara, who disagrees, and eats just as much carbs as protein, although the ideal ratio varies based on your goals. "Whatever you eat to get the results you want has to be sustainable, otherwise you're going to end up right back where you started with the same habits that got you there."
