Extension Layup Drill
Here is the Extension Lay-up Drill from the Playmakers League curriculum:
The drill is a series of one-dribble, three-step lay-ups: Traditional lay-up, reverse lay-up, inside-hand lay-up, and crossover lay-up. The traditional lay-up and reverse lay-up use an outside foot pivot foot, and the inside-hand lay-up and crossover lay-up use an inside foot pivot foot.
