good start man. Remember you are only 14. I was a wrestler from 4th grade all the way through college and was constantly cutting weight. I wrestled 112 as a senior and 125 in college and I'm up to about 187 now just two years later.
Just eat big and lift heavy and don't over lift any one body part. If you are looking to put on size less is more. Meaning you don't need to go in and hit 19 sets for chest like I see alot of the kids your age doing when they are in the gym. Trust me I used to do the same thing when I was your age. I took my work ethic from wrestling that told me the more I trained the better I got and figured if 10 sets of chest was good than 12 must be better and 14 better yet and so on and so forth.
As for diet stick to lean protiens:
chicken breast,tuna,egg whites, turkey breast, cottage cheese
and for carbs:
rice,whole wheat pasta,sweet potatos,non fat yogurt, Apples,bannanas, Oatmeal,veggies
add to that some healthy fats: fish oil, flaxseed oil, extra virgin olive oil
as for you doing 275 x5...It's possible. The strongest area of most wrestlers are their hips and legs. That's where all your power to lift and throw and defend against attacks on your legs comes from. You can't be competitive in wrestling without a strong shifty pair of hips.
However I'm inclined to believe that like most kids your age your squat form is probably not perfect and that you aren't doing ass to the grass squats.I see kids in the highschool gym where I teach, doing half squats all the time and talking trash like they can squat almost as much as me but when I have them squat correctly their knees buckle and they can't even get one rep up.
and just what is the difference between 220x10 and 275 x 5? If anything I would think it is actually more difficult to put up a weight that is only 55 lbs less for twice the reps. that just doesn't make a whole lot of sense to me.
keep up the good work bro. and good luck in wrestling.
