I'm 16 years of age, and I've been working out about 4 months now. I workout about 5 times a week for aproximately 90 minutes, and I do cardio about 2-3 times a week(mainly whenever I have the time.) I weigh around 160 pounds, and my daily activity(not including work-outs) is about a 2 out of 5. I have no idea what my body fat percent is because getting my hands on a pair of fat calipers isn't exactly easy.
Anyway, I'm looking to gain some muscle mass. I'm wondering how many calories a day I should be taking in. I know the protein grams I should be having is somewhere close to my weight, but I have no idea how many calories. Also, if anyone would be kind enough to give me some hints on the types of food I should be eating or anything related to my "should be" diet I would be very appreciative. Thanks.
