Six-pack abs are impressive to look at, and often conjure up images of hours spent in the gym — however, obtaining a strong core is surprisingly easy, if you know how.

For this position, you lie on your back on a yoga mat with your legs in the air and knees pulled towards your chest. Fingertips should be placed behind your ears.
