The more sore your muscles get post workout the better for muscle growth correct? My arms are so incredibly sore, more than theyve ever been, I can't even extend my arms, I have to walk with them sort of retracted. I didn't even workout that heavily! Just the first time in a while. I'm 18 now and should be at the peak of ability to gain muscle. So basically, my question is, are my muscles extra sore because of the increase in hormones? I often hear certain gear makes people more sore than usual.
