I have 3 days at the moment. Plus 2 days of SS cardio...so it's not too bad.

Personally I would wager that as long as you're able to lift heavy, most muscle mass will remain. But if you tax the CNS heavily and dip in weight, you could see some muscle loss.

But from a pure strength perspective, I see so many powerlifters doing GPP training on off days like sled dragging, etc. Stuff that taxes the legs. It would seem on a cursory level that the CNS is much more able to adapt to short bursts of low intensity work, even if this work does involve the use of some resistance.

Just thinking out loud...
Thing is, I usually don't weight train until about 8-9 hours after my HIIT session, so I have plenty of time to rest up/take a nap/drink some coffee, and my weights aren't really affected.

I could try experimenting, but for example yesterday I trained hamstrings pretty hard...and this morning I'm sore as an ulcer, and I can't imagine doing any HIIT today.
