These 4 Easy Plank Exercises Will Transform Your Abs

Plank

1. Assume a plank position, resting on your elbows, with the balls of your feet about shoulder width apart. Your elbows should be directly underneath your shoulders, your back should be flat, and your neck should form a straight line with your back. Tighten your rear end and abdominals and the front of the thighs.
2. Hold this position for the suggested amount of time. Do not allow your lower back to sag.

What it does: This plank exercise strengthens the entire core. (Find out more tips to get better abs without crunches.)

Form tip: To intensify this exercise, narrow your base of support by moving your feet closer together.
