this motion on court
Player and coach (or other partner) face each other about five feet apart. Coach tosses ball underhand to player. Toss should be to forehand or backhand side, not directly to player. Player should lean to left or right to catch ball in air while maintaining good balance. Player should remain facing forward rather than turning to side to catch ball.
Too easy? Stand farther apart and/or toss ball farther from player.
Too hard? Let ball bounce before player has to catch it.
