Warrior 3 Deadlift

Standing on one leg throughout challenges your balance while working your core, back, glutes and hamstrings.  You can do it with weights (left picture) or without (right picture).

Step 1: Begin in a standing position, feet hip width apart.  Extend the right leg back such that the toe is raised off the ground (or barely touching if necessary).  Keep a slight bend in your left knee.
Step 2: Slowly bend at the hips and lift the the right leg back into Warrior III position.  Flat back and straight right leg.
Step 3: Engage the glutes, keep a flat back, and rise back up.  Try not to touch your foot back the the ground.  This is about control and balance.  Focus on a point on the floor a few feet ahead of your to keep your balance.
Step 4: Repeat for the designated number of sets, then repeat with the right leg grounded.
