A regular pushup works your core. A reverse pushup will work it so hard your abs will want to form a labor union. “When your legs fire your body forward, your core has to work extremely hard to decelerate your body,” says B.J. Gaddour, C.S.C.S., director of Men's Health StreamFIT. So this ab exercise not only works your shoulders and arms, but gives you a killer core workout at the same time.
The reason: Classic ab moves like crunches and situps work the muscles that allow you to flex (that is, round) your lower spine. True core exercises, on the other hand, train the muscles that prevent your spine from rounding. They also allow you to transfer force from your lower body to your upper body (in a golf swing, for example), and vice versa.
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.
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."
