Hi, i'm turning 18 and have had a long battle with health issues, one of them hormonal. After boxing for a year and sparring heavily i began to feel like shit, bad erections, suddenly i couldn't put on muscle like i used to, the hormone panel awful as well. Both the Endo and my main doctor believe it is a real possibility i fucked up my pituitary with a blow to the head.
I intend to step up weight training, instead of skimming the surface while being a boxer. I want to dive in and slowly move away from boxing. I have always had a part of me (maybe in my blood, my mom was a bodybuilder) that wants to get strong, go heavy and build mass.
What lifts do you recommend i adopt first? As a boxer my leg training has been low weight very high rep, i don't have much mass in my legs at all, and because my trainer is so old school, we have done nothing to isolate the back, he has me isolate abs after every workout and neglect the back.
