In Praise Of Frequent Praise

The other day, during my personal training session, as I progressed through repetitions of the designated exercise, the trainer kept saying, "Good!" "Good job!"  "Great work, Ken."   And while I didn't think I was doing anything particularly great, I was impressed by the frequent praise as a motivational tool.  It was not just one attaboy after the set was completed, but it was consistent compliments as I was moving along.
