Ok, long story short, I have had arthritis in left leg since 16 months old. Docs told mom I would never walk. Obviously not the case. Last week squated 3 sets of 365 for 7 reps. However, my left leg just does not have the size. I attribute it to many years of having limited or no use, but dammit I want it to catch up. Has anyone had to recover from a broken bone, knee surgury etc and have some good advice for helping a lacking limb to catch up?
