Alright I've been having issues with some joints for about 6 years now. I'm only 25 and I've had tendonitis in my shoulders and my knee bugs me from time to time. I'm 6'3" and I down to 163 pounds and I need to gain mass but my old injuries are holding me back. I can eat whatever I want and stay shredded bc of how crazy my metabolism is but the amount of food I eat wont matter if I cant do the right amount of training so the diet thing dosnt matter at the moment. Im pretty sure overhead pressing is out and basically all straight bar movements are as well. I've done research and countless workouts experimenting on what works and what dosnt. Inverted rows, neutral grip chins, pushups, db curls, farmers walk, sled drag, sprints, seem to be what im stuck with. And this might seem like an excuse but squats and deads just don't seem like they are gonna happen bc of the length of my femurs. Rear elevated split squats worked for a while but my rear left knee started getting irritated during the movement so I stopped with those. But with all that said I just cant seem to progress. I've been doing bodyweight mostly and even then my joints flare up and crack and pop and what not. I know that I will need to keep adding resistance to my lifts but it seems like my body dosnt want to cooperate. I feel like I am condemned to be stuck at my current size and its very frustrating. And Im not looking to get huge. From how it feels I think I have problems with my supraspinatus in the right shoulder, and im not sure about the left but the mri showed tendonitis on the front of the shoulder. And anything can cause irritation so it isn't just one thing in particular that im doing to cause aggravation. And I've been to PT more than once and they think its strange bc I have good muscle definition and I kept getting stronger but the pain never stays away. Does anyone else have these issues? Does anyone have any advice for gaining strength and size with a problem like this?
