Start off by standing straight with your feet shoulder width apart. You can place your hands at your side, across your chest or at your sides. Do not use your hands to push of your thighs.
As you begin to inhale, step out to one side. Let's start with the right foot, keeping your left foot planted on the ground. Keeping your body straight.
As you step out with one foot, once it is on the floor bend at that knees lowering your body. Your knee and foot should be in a perfectly vertical line.
Once your thighs is nearly parallel to the floor, hold for a second or two then extend back up and step back to the starting position.
The further you stretch and the lower you go will increase or decrease the difficulty of this movement.
