INSTRUCTIONS
1. Stand with your feet hip width apart. Hold the kettlebell by the handle with both hands. Make sure you have a quadruple extension – ankles, knees, hips and torso. (See Fig. 1)
2. Step to the side with one leg and descend into the lowest lunge possible aiming to allow the bottom of the kettlebell to touch the floor on the inside of the foot. Make sure you keep the opposite leg straight. Your feet should remain parallel and facing forward. (See Fig. 2)
3. Keep the weight onto the heel of the leg you stepped to the side with, drive the hips up and step back in to return to the start position.
4. Repeat the movement from point 2 on the opposite side.
