How to: Lie on your left side with your legs straight and your right leg stacked on your left. Position yourself so your weight is resting on your left forearm and the outside edge of your left foot. Your elbow should be directly beneath your shoulder, and your upper arm should be perpendicular to the floor. Align your body so it forms a straight line from your neck to your ankles, and place your right hand on your hip. Lower your hips toward the ground a couple inches, then come back up to start. That’s one rep. Do 15 reps on each side.
On hardwood or tiled floor, place feet on two sliders and assume a high plank position (hands under shoulders, soft bend in elbows, butt and core engaged). Pull feet in toward chest, bending knees until you’re in a bear plank, knees below hips, but still lifted off floor. Slowly push feet back to high plank. Continue to repeat. To make it easier, move one leg at a time.
When it comes to improving core stability, the plank has your back (and your front!). By working your transverse abdominis — the deep core muscles that wrap around your middle — as well as your back, shoulders and glutes (yes, you should activate your butt, too), you get a full body burn in one isometric movement. But the best thing about planks: You can continuously switch them up and make your muscles work even more. Check out these creative twists on a typical plank routine and you’ll see what we mean.
Do it: Lay face up on the floor with arms straight above your shoulders. To start, bring your knees directly over your hips and bend at the knee so that your calf forms a 90-degree angle with your thigh. Next, simultaneously lower your left arm above your head while straightening your right leg and sending it towards the floor. Pause, return to the starting position, and then repeat on the opposite side. Do 14 alternating reps to complete one set.
“I alternate between all-out effort sprints (30 to 60 seconds) and walk/jog as a recovery until I feel fatigued. Intensity is key. Abs work as stabilizing muscles during a sprint, so the harder I push myself the harder my abs will work! Plus, there’s no equipment required, and I get a high calorie burn and full-body workout done in very little time. (I tell myself I can do anything for 30 seconds.) Depending on how I feel, I’ll either add this to the end of a routine or make it my entire workout, two to three times a week.” —Suzanne Cover, @suzannecover
One of the best tricks for getting six-pack abs is to lose some weight, even if it’s just a few pounds. And one of the best ways to lose weight is to adhere to the 80-20 method. Since it takes your brain about 20 minutes to “catch up” to your stomach and realize that, hey, you’re full, oftentimes, you’ll eat more than you need to. So eat 80 percent of what you’d normally eat, then wait 20 minutes. If you’re still hungry, eat the remaining 20 percent of your portion. But chances are, you won’t be hungry one bit.

The inspiration for this exercise might come from skiing, but it's also an effective way to prepare your midsection for many sports, including tennis, softball, and golf. The reason: "It trains your abs, lower back, and hips to work together to rotate your body from side to side," says Durkin. And the more powerfully you can rotate, the faster you can swing and the harder you can throw.
You can find myriad articles, blog posts and videos offering advice on how to develop a six-pack, the kind of chiseled abs you'd expect to see on world-class athletes, like Olympic gymnasts or swimmers.

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."
