Warm-ups are all mental. I remember watching a team called Duzbra.( i think thats the right spelling). They didn't use pucks at all in their warm-ups. Their record was 99-1. Most of us like to use pucks. Long shot I feel are worthless. You will hardly see straight long shots. The shots that are close in and break aways will help the most, because those are 95% of the shots you will see. I got mad at my team because they would only take slap shots, which don't help. Wrist shots that are close in are the best warm-ups. Only after a nice streching routine.
