Place your one of your feet onto the middle of a resistance band. Leave other foot out. Your feet must be a bit wider than your shoulders. Tighten your abdominals and avoid arching your back. Hold other side of the band with opposite hand so it crosses your body.
Maintaining a slight bend in the elbows at all times, slowly raise your arm up to get it to the right side of your body and parallel to the ground at the same time . Be sure to favor the front as you lift.
Once your arm reach parallel with the floor, pause, feel the contraction, and slowly lower back down.
