I am doing leangains. It requires you to get 10g bcaa's before exercise.
My question is after which level of intensity am I going to start breaking down muscles (to use them for energy)? Walking is obviously acceptable, even fast walking. What about running and maybe a little more? What about light sports like a low intensity season of tennis (I am am playing for a long time)?
Thank you in advance.

LG doesn't "require" BCAAs before exercise, fasted or not. Martin Berkhan recommends it to avoid muscle loss, but a recent study has made me re-consider my position: http://www.gulfcoastpersonaltrainingllc.com/why-supplementing-with-branched-chain-amino-acids-bcaa-pre-workout-will-be-detrimental-to-fasted-training/
Don't have an answer to your question, though. Martin B. and Andy Morgan don't recommend cardio if you're on a cut, though.

I did a half marathon fasted today . . . in retrospect, I'd say that's pushing it. Seriously though, strength training seems to augment the fasting process while endurance/glycogen-dependent HIIT seems to bring about a downward spiral of complete and utter SUCK.

I think it depends on your metabolism.... for example if you been lc for a while your body gets more efficient at burning fat, so at 100% intensity you might be using 60% fat stores and %40 glycogen.... if your a sugar burner if might be much less, so you'd have to lay off the intensity some. When you run out of store3d glycogen, you feel it, it's often described as "bonking" by endurance athletes. I know this doesn't exacty answer your question but I would guess you'd want to keep it below your latcate threshold at least. Think about it this way: if you can't carry on a conversation while jogging, slow down until you can. Tennis is a different story, since it's short quick bursts followed by rest. IF your playing for a long time chances are your depleting glycogen...
