I tried to do some Joel Jamieson-inspired stuff and it was so complex and confusing trying to figure out how to follow his recommendations into an actual program that I just kind of gave up on it. I also don't really have a lot of say over what I do in BJJ. Like, I can't go in and tell my coaches that I can only do 6-minute rounds with my heart rate not over a certain amount and a certain rest period (etc.) the way a full-time fighter may be able to do.
Anyway, I think there's a difference in the amount of strength work needed based on size, rank, etc. There can't be a one-size-fits-all prescription.
Hmmm. Let me think on this more.
