Lengthen the hamstrings and challenge your balance in this yoga-inspired, functional exercise. While it may seem simple, it will make your hamstrings burn.

Stand with feet together and arms at your sides.

Inhale and slowly bend from the hips, lowering the torso and extending the arms. As you fold forward, raise one leg until torso, arms, and leg are parallel to the floor. Exhale as you lift the torso and lower the leg in one fluid motion. Repeat with the opposite leg.
