What are the buzz words that I can look up to find out more about that? Periodization? What else?
In my case you're right: I wasn't lifting a lot of weight relatively speaking. But I would always lift until I had some soreness the next day.
I know that some would disagree with this, but what I always noticed was that the muscles where I got the most soreness (triceps and chest) were the muscles I got the most growth.
Anyway, my goal is probably at this point more to put on muscle. If anyone can give me any buzzwords to look up in the search engine on this subject, I would appreciate it. I'll do the research, but I don't even know where to start...
