What heart rate should you be aiming for on a 3 hour bike ride?
I was told you should keep it well below 70% for a good workout. And it was not healthy to keep your heart working that high.
I figure if I was not weak our out of breath I was doing ok.
Would a heart rate moniter be helpful or is this taking the fun out of bike riding?
What sould a person pay for a decent heart rate moniter?
