I never took wrestling in H.S., but I've been doing Judo for a while now.
I ran into the H.S. wrestling coach and he wants volunteer coaches, so I told him I'd observe before actually contributing to the class. I've been watching things for about 3 weeks now. Here's what I've noticed:
-- These guys go non-stop, all out, for at least 3 hours a pop. I show up at about 3:00 and they're already stretching out. When I leave at 6:00 they're still going. 5 days a week. 6 during the main part of the season. Hardcore work ethic.
-- Shoot, shoot, shoot. They work on shooting for doubles, singles, fireman carries, etc, over and over and over. The basic entry footwork seems to be the same, so get that down. In fact, they drill the same entry over and over for about an hour: Plant with a foot, take a big step with the other foot and drop to that knee, etc...
--Slackers stand out like a sore thumb. That does NOT mean that freshmen who are just learning things stand out negatively, what it means is that, because all freshman are just learning things, the ones who don't TRY really look bad. Effort is 90% of the game your freshman year. It doesn't matter if you suck because you're expected to suck, just give it everything you've got and you'll be fine. You'll gain instant respect if you are seen as putting your heart into every session, regardless of your natural ability.
Stick with it, Don't quit. You'll never regret it.
