Years ago when I was trying to get in shape on a stationery bike I was checking my heart rate using the traditional pulse method and the charts for my age. Whenever my heart rate climbed into the zone for my age, I felt tired the next day.
Then I remembered Covert Bailey's book Smart Exercise in which he says that a person whose resting heart rate is above average might not fit within the typical scale and suggested using the talking test instead. Basically that means that you should be able to say a short sentence without gasping but not too easily either.
So, I thought the opposite might also be true -- that a person (like me) whose resting HR is below average might also be the same.
So I tried the talking test -- "Hi my name is __________ ____________" <breath> "I live at _______________" <breath> ___________________
I found that I not only felt good the next day but my fitness improved almost daily, and I began to rely on this method instead of checking my pulse.
Just wondering if anyone else employs this method and what you think of its reliability. For me, the results were noticeable. I wear a HR monitor now on some of my rides just to see what it reads and I use the talk test now and then and compare the two. The upper 150s seems to be my threshold of exertion right now.
