I'm 15 and haven't been lifting long, nor do I know very much about lifting. I was told I'll need to have surgery on both of my shoulders soon because I have extreme shoulder instability (about 15 dislocations a month) though so I'll have to take a break. I'm not very sure of my bf but I'd estimate 10-12% I've been reading some of the stuff for a while and am excited about becoming part of the community.
My stats:
36 cm bicep
85 cm waist
102 cm chest
57 cm thigh
28 cm forearm
185 cm height
77 kg weight
37 cm neck
