A cross between a leg raise and a crunch, the V-up is championed by personal trainers and #fitspo influencers alike. It hits both the top and bottom sections of your ab muscles, granting definition in those hard-to-hit spots. Here’s how to do it. Lay flat on the ground, arms raised over your head. Raise your legs, keeping them straight, toward the ceiling. At the same time, try to touch your toes. (You don’t have to fully get there.) Return back to a flat position. That’s one rep. Do as many as you can. Once you can effortlessly do four reps of fifteen, start adding a medicine ball for increased resistance.
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.
