I never did more noteable aerobic training beside long kyokushin sessions. I guess it that low because I'm only 66kg/184cm and so there's not that much bodymass to supply
My aerobic endurance is good I think, so I don't think it's something wrong (Also had recently a checkup), I can grapple 3 hours in BJJ (5min rounds) without problems. I can't explain that because I never did sports before I started kyokushin.
There could be a correlation between low RHR and longevity, do you know about any studies about that subject?
