thanks for everyones replies. After doing more research online, as well as studying my diet I realized I'm already eating a fairly balanced high calorie/high protein diet which should meet and exceed all the requirements needed to build muscle as I work out.
Some advice from Syncro and other online research really tells me I need to focus on building a more focused training schedule and targeting a few areas I have been neglecting (mostly pullups/chinups and horizontal pulls - pull type exercises in general). Also alot of great pointers for increasing the difficulties of calisthenics can be found online so rather than doing 7 sets of 12-15 regular pushups, I think I'd be better served working at lowering those reps by doing decline and uneven pushups etc.
if nothing else this thread really made me dive into alot of online research and realize where I was coming up short.
