Begin by positioning the hands on the bar at roughly shoulder width. After you have a firm grip, walk yourself back into a plank with your arms extended in front and your heels and knees together. Squeeze your butt and abs to form a solid middle. Externally rotate your hands outward (thumbs should be near 11 and 1 o’clock). Wrists, elbows and shoulders should be nicely stacked in line. Externally rotate the shoulders and elbow pits outward to tighten the shoulders while holding the plank.
To better engage use the tops of your toes rather than the bottoms to balance on.
