What's the best way to get to my max heart rate please?
I know the formula 220-age = MHR 220-34 = 186
My polar RS200SD HRM gives me an estimated MHR of 174.
But when I'm running, usually 5km my heart rate can reach 182 and has when I'm pushing it reached 189. Give that I seem to be doing work for 30mins in the 90%+ zone it seems likely my maxHR is higher than suggested (else I would keel over I guess!)
What's the best way to get to my MaxHR then - is it just to shove myself on a rowing machine and just attack 1000m till I can give no more? A treadmill would risk me flying off the back. How long does it take to get to MHR?
Be grateful for any help.
