I've been looking for a structured practice program and came across this.

I'm going to alter it a bit to suit me but it looks like a balanced program that makes the short game practice a bit more fun and challenging than just taking a couple of balls to the practice green and knocking it around without real purpose.
I'm not going to do the 6 shot shapes with the full shots as I'm not good enough for that yet. Mainly working on consistent impact at the moment (center hit and square face/down the line path)
