Place one end of bat down on ground approximately arms distance to your right side while holding the other end with your right hand. Lean to the right so that the weight of your body is supported by the bat then stretch your opposite arm directly over your head and reach laterally towards the bat.

Lift directly above your head then bring bat down to rest on your shoulders behind your head while continuing to hold onto it with your hands.
