Position the sandbag at the chest with arms wrapped under it. As a guideline, the ideal height of the box is that the knee should be in line with the top of the box. Step onto the box in a heel to toe fashion then extend up onto the top of the box and stand tall. The foot should face forward and be in line with the knee and hip. The knee should track in line with the middle of the foot. Reverse the movements back to the start position and keep the knees, hip and toe in line. Alternate the legs after each repetition. 3x10 Rest 60 secs
