I wrestled in high school and always trained in the off-season. I think I can offer you some good advice. When the season starts, stop lifting completely. If your practices are anything like mine were then they will be 6 days a week and 2 hrs long. First, an hour of pure cardio with a lot of pushups, wall pushups (for shoulders) and tons of abs work thrown in for breaks. Then when you are actually wrestling in practice for the other hour, you are giving your entire body another good workout, this time with plenty of unintended extreme stretching and short bursts of maximum effort.
In the off season, try to concentrate on your entire body. Don't let the kids in that gym that love to show off doing curls and benching effect your training. It is probably more important to focus on pulling movements and shoulders, especially your rotator cuffs. Wrestling relies a lot on core strength for twisting type movements, so abs, obloquies, and lower back work would be very helpful too. Right now, you are so close to the season that I would recommend doing a full body workout every other day. Don't over train of course so don't always go to failure and always do at least 12-15 reps. Do a lot of cardio as well.
