You wanna make sure you switch it up a bit cause if you work the same muscles too often it could have a negative effect on body building. I like to do my upper body workouts on monday than tuesday I do my core workouts, wensday I do my leg workouts, thursday I do coditioning (run 3-7 miles). Friday, saturday , and sunday I take it easy and then monday I start all over again. Protein is also very important after football and workouts I drink a minimum of 25 grams of whey protein. You wanna eat/drink your protein either 30 minutes before or after your workout for maximum effect.
Body building also takes determination if you can just stick to it the reward is great!
Ha ha Good luck.

Ps. p90x is also a good progam I would reccomend it. I have done it twice and very much enjoyed it.
