This stretch targets your hip flexors, front body and lats. Do 6 on each side.
Stand with your feet together and then take a large step to the rear with one foot, placing your toes on the ground and keeping your leg straight as you bend your forward knee. Simultaneously reach both arms up and overhead, doing a small backbend if you can. Push off your rear foot and lower your arms to return to the start. Do all reps on one leg, then switch.
