Sets: 4 Reps: 6 (each side) Rest: 30 sec.
Hold a weight plate in both hands and stagger your stance so that one leg is in front of the other and your hands are to the outside of one knee . Contract your abs and swing the plate diagonally upward—as if you were swinging an ax—to the outside of your opposite side's shoulder . Reverse the motion to return to the starting position. That's one rep.
