Hey, I've been doing all my conditioning training with a mouthguard in lately..grappling, sparring (of course), running...and found that it is a lot harder, especially running, my heart rate goes through the roof... I find that I have to take short breaks running with the mouthguard in when I never had to without it.anyone else do this?
