Re: BJJ Specific LSD Exercises
The trick with BJJ exercises for LSD is keeping your heart rate in the aerobic zone for 45-60+ minutes. It is very easy to overdue it after 20 minutes with a lot of typical jiu jitsu/grappling drills.
I think that Joel recommends, for example, when doing ground exercises that you lower your heart rate target by 10 bpm. I'm not 100% on that, but I'm pretty sure he made that distinction. That makes it a little tricky. Many if not most grappling drills typically are done at a pretty fast, intense pace.
