Want abs like this? Eat clean, and do lots of these.

How to Do It

1. Lie on your back on the floor and raise your legs so they’re perpendicular to the floor. Extend your arms up over your chest.
2. Crunch your torso off the floor, reaching for your feet (though your hands don’t have to touch them). Hold the top position for a second, then come back down.

Quick Tip

Perform toe-touch crunches (3–4 sets of 10–20 reps) at the end of a workout.
