What if, we give the adult a racket is 3lbs heavy, to hit a tennis ball that 5 times heavier... would that cure the arming problem?
Using 2 hands on both sides like that helps him automatically engage the core more.
Some coaches like Dave Smith advocate starting all beginners with 2 hands on both sides.
