As anyone who's seen my log is sure of, lately I haven't been lifting. I'm 17, and know it should because I know the edge it will give me in the future. I train BJJ 6 nights a week because it isn't very strenuous given my style, but I am still interested in dramatically improving my work capacity, because I feel I will then feel more fresh and have more inspiration to lift. So my question is, HOW MUCH GPP IS TOO MUCH? Should I just start DOING more? Or should I go about building my work capacity with mostly GPP?
GPP is exactly that: general. You should probably be looking for weaknesses (what tires out first when you are sparring) and work on those weaknesses first. GPP probably 1-3 times a week is plenty.
However much you can do without it negatively affecting your recovery and preparedness for BJJ training.
I've never been so wiped out that I couldn't roll. Now, I'm not recommending everyone should do 20 rep squats the day before a tournament, but once you start rolling, I think you'll be surprised how quickly you forget about fatigue and tiredness.
