Keep my body guessing.

Today I had my second of three WEEKLY "workouts". My trainer said that he's "DEFINITELY seeing a greater range of motion and strength in" (my) "left side".   YAY! So, my trainer recommended I try a new exercise on my "OFF-days": I park my wheelchair alongside/"parallel to" my parallel-bars.   My "assistant" will help me lift my LEFT arm up, so I can grab and hold a bar with my LEFT hand.    THEN, I--ALONE--drag my LEFT, INJURED hand ALONG a metal bar.   I push my LEFT arm as far forward as I can.  Then, I pull it as far BACK as I can.   THIS EXERCISE will--over time--increase my range-of-motion.   (I REALLY LIKE THIS NEW EXERCISE!)
