Benefits

Improves back strength

Helps to give hips, thighs and abs tone and definition.

Targets the iliopsoas muscles of the hips and also also engages tons of thigh muscles, including the sartorius, pectineus, rectus femoris and the adductors, as synergists, or muscles that help other muscles complete a movement.

The quads, abs and obliques – or “outer abs” – also get a secondary workout as you lift your legs skyward.
