Thanks for the reply.
How do your actual Heart Rates compute in terms of % Max HR, i.e.
Is normal is 70-80% ?
Is intense is 90+% ?
For the last year or so, I’ve been doing 30 minutes of elliptical at a constant 80-90% that equates to 130-140 BPM.
As a former all-star athlete, the lack of progress is quite frustrating.
My extremely alethic son gave a copy of “Heart Monitor Training for the Compleat Idiot”, many years back.
First I thought it was a ‘message’, no he said it is well used among his group.
I love it!
Over the years I have used it for running, cycling and now rowing. a copy for $3.74 postpaid.

The book and HRV are my main programs.
