Judo is fun,
Did it for 8 years. I wrestled too, and found the conditioning
for HS and college wrestling far more comprehensive and intense.
we did allot of Judo specific things, sort of what you might find in a Judo/BJJ warm up, running, skipping, tumbling…
crawls, forearm pulls, etc.
But what we really did is burpees.
Lots and lots of burpees.and Medicine ball slams.
I would check out the tabata protocol
20 seconds work, 10 seconds rest x8
4 minutes of hell.
do it with jumprope, pushups, BW squats, burpees etc.
I would even say a rowing machine is really underated.
I have done the tabata method with body weight squats, and it did suck. I am curious though how burpees would go…
