actually i realized my pt basically has me doing this exercise but with my arms out at 90 degrees ilke an L on both sides..i think to keep me from irritating my arm pit. anyways im not that bad at it actually!you have to keep your hips tucked in tho or else you feel it in your lower back.

anyways eventually she will move me to all fours.

i tried doing bicep curls and my l arm got SO FATIGUED. i really think its my shoulder/lower bp/arm pit that carries all my neural tension.
