When I do cardio I tend to stay at around 85% my max heart rate

How do you know what your max heart rate is?

He overclocked his heart until it wouldn't boot then multiplied that by 0.85

He pushed it to the limit. (THE LIMIIIIT!)

220-age lol

i guess that formula is off for me, my MHR is probs higher than that judging from how 85% feels?

so is my max hr being above 220-age a sign im fit or unfit?

I need some resolution. Did they make it back?

That's normal for unfit people (myself included, can keep at 185 bpm for half an hour, ~206 max).

Btw while on keto I can run at 95% for an hour. Feel it only in the last ten minutes or so but after running I'm completely dead for 24h.

To find your max bpm just warmup with a jog and then do a lap at your maximum speed.
