NR2 i did that worked out till it turned out i got genetic defect and from having 6 pack runnink 10k a day i can barelyu walk and sit now. WORKING OUT NOT ALWAYS PAYS OFF made me -blam!- criple...
Man I'm sorry that's rough. I don't know what to say other than I wish you all the best.
I wrestled in my younger years and I'm almost 32 and my bodys cartilage is deteriorating due to how much I over worked it. So I don't have it as bad as you, but I can understand a little about what you're going through and alot of people won't get it.
Good luck brother
