Over a year. The problem is that I have very tough fibers, and the better part of that year was pretty much me getting overzealous and injuring myself, and then having to take time off. The injuring myself, and taking time off. Then injuring myself, and finally getting smart enough to sit down and take the time to toughen up my soft tissues. Now that they can take the abuse, the gains are marching along at a nice, steady pace.
