Does your school have a strength and fitness football coach? You should hook up with him and find out what he has to say. Especially since you can talk in person and he probably knows a lot more about you than the rest of us do. Depending on your goals you might just want to talk to the coach for whatever position you play.
Here's one piece of advice I can give you that it seems most high school kids don't want to do-
When working out it's very important to work out THE REST OF YOUR BODY. I was guilty of not doing it, and so was just about 80% of the football team I played on. Break your week down however you want (as long as you allow adequate rest for your body) but make sure you work all parts of your body. Legs, back, abs, chest, shoulders, arms.
When you do compound workouts with your legs like squats and dead lifts it will promote growth hormone in your body. I don't think I need to tell you how that will help the rest of your lifts. Also, get on a GOOD protein with casein, whey, and amino acids. Especially focusing on the amino acids part. It will help with your muscle recovery.
Last, but not least- make sure you're doing your lifts correctly. Check out these sites and hook up with a knowledgeable workout partner for some guidance.Website 1 Website 2
