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.
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."
