TRX curtsy lunge/crossover (Lunge, curtsy, with TRX)

Stand up straight with your feet shoulder width apart and the straps short.
Your arms should be out in front of you holding the straps.
Keeping your arms straight, squat down on one leg whilst simultaneously crossing the other leg back behind.
Lower your body down until your back knee is just above the floor.
Push back up through the legs rather than pulling with your arms.
