"Sense/Feeling of Accomplishment"

Yesterday, I tried this new exercise during my WORKOUT.  My trainer attached this pulley-device above a closed door.  I  maneuvered my wheelchair near said "pulley".  I would then grab the TWO handles and, PULL MYSELF UP into a STANDING-position.  While I was STANDING (for ~10 seconds), my trainer would  LIGHTLY/MINIMALLY hold/assist me--JUST to STABILIZE/BALANCE me.   I did said exercise five times.
