I guess I'll go ahead and bump this 8 month thread in hopes or someone else benefiting from my reply. You specifically said you want to get in shape for Football. I remember my first year if High school football; I'm sure there was some sort of summer training program that they had and I'm sure it was hell. Anyways, for people wanting to prepare themselves for something like a summer training program the BEST advice I could give anyone is do A LOT of cardio and try to boost your stamina as much as possible. Running a few miles a day (aim for at least 3 in 25-30 minutes and get better from there) will help you a lot more than you might think. You could also do some general weight lifting but I would recommend doing lighter weight and more reps, this way you can get used to the different techniques and master them before trying anything more heavy and dangerous. Especially as a freshman, the team will help you a lot in the gym. You just need to be able to give it your all. If you are pooped after the warm ups and stamina drills, you won't be impressing anyone. Best of luck
