I've been working on my cardio for a while but it still isn't at the level where I want it. Every sparring class, I spar about 10 rounds with a lot of different people. Towards the end, I tend to get owned and my hands feel super heavy. My question is, what is your plan a, b, or c when you get gassed? How do you also deal with it? Any immediate solutions to it? I know this may be a stupid question but if you're fighting a bout and you're super gassed at let's say round 2, deep breathing is the key. Would hyperventilating (breathing even faster than you already are on purpose), which would allow more oxygen intake, be a good or dumb idea? Anyone ever tried? What would you do?
