Stand on a decline board or wedge with the suspension strap to your side.
Loop the strap around your waist and lean to the side so that your body stays tilted at 45 degrees and your feet are flat on the slanted board.
Keep your body as straight as possible during this exercise.
Simultaneously lift the upper leg from the step while lifting the opposite arm up.
Lift the heel of the lower leg off from the step to finish the movement.
Return to the starting position by lowering the arm and leg and repeat the movement.
