Standing with the right foot firmly on the ground.

Slowly descend until the torso is close to parallel with the ground while keeping the left leg straight.

During the descent, the left leg should be traveling in a straight line backward with the toes pointed straight down to the ground. The hips should remain parallel with the ground, NOT tilted.

Feel for the stretch in the hamstrings, as well as the hamstrings contracting to return to the starting position.
