Nice thing about the clinic I attend - goalies who want to just face shots from the skaters attend for free, and they're at one end, and then goalies who want the specific instruction get the middle and don't have to face any shots if they don't feel ready. I mean, in the drills you usually get shots, but it's very controlled, and 40 minutes of a 55 minute clinic could be devoted entirely to movement. There's usually 3 goalies, but the minimum is one (of course) and the max is 6. The coaches have all been good to us allowing us to rest when we need it, or modify drills to more experienced or less experienced players. (for example, the coach might want a more experienced goalie to butterfly slide from post to post, but would tell me to shuffle.) Actually, the ice is divided in three - adult novice players at one end, goalies in the middle, and kids at the other end, so you can also lend yourself to the kids' group if you feel that's more your speed (and it gives the kids a thrill, shooting on a real goalie). Then a six year old dekes you out of your pads and you get to feel shame. Stretching is a process. A little bit at a time. Most of the time, about 20 minutes of my workout is devoted just to stretching. Groin, hips, back. Sometimes if the trainers are around, I make sure to do really pretzely stretches to freak them out. But I also work at the gym and enjoy messing with my co-workers and don't advise that as a proper training technique.
