Using HR variability, as some propose , is only good for resting RRate
I would like to quantitate my subjective RR / exertional rate
though a block timer app would probably do the job more simply
HRM are still popular because they can be inexpensive and work for everything: bike, run, swim, hike, walk, gym, etc., etc. Thus triathletes all use HRMs. They also have a big price variation, from inexpensive up to 1/2 the price of a power meter.
HRV can be used actively, not only resting. I use an Android phone, Elite HRV with a bluetooth strap and transmitter. I haven't done, but I suppose one could put the phone on a mount or in a jersey pocket and go riding with the app running. I take both resting and standing HRV every morning.
