This is how urban tennis myths get started, once again we are talking about the post coin toss "warm-up" not what's done for training/practice two hours before a match. I defy you to show me any pro match seen on TV where men or women pros do mini tennis after the coin-toss warm-up.
If you have proper stroke technique, you can get "blood to your arm", hitting from the baseline, using the force of gravity to return shots reaching your opponent's baseline easily.
