Sometimes before practice we play mini-tennis and one of my teammates likes to play mini-tennis before we hit. I cannot understand what it is supposed to help. All I do is block or push the ball back. There is not enough space to do an actual stroke so most of my backhands end up being more like drop shots. It annoys me to no end to just stand around pushing the ball back and forth over the net doing nothing. What is the purpose of mini-tennis?
