I have entered the world of heart rate monitoring for training. I nearly gave myself a heart attack this morning when I saw my peak! Peaked at 201 briefly this morning, but i was racing a fixie when it happened! Averaged 153. Read this about measuring recovery:
One way to determine if you are reaping the benefits from exercise is to calculate your Recovery Heart Rate, a measure of how quickly you return to your resting heart rate after a workout. To calculate your recovery heart rate:
Take your pulse ten seconds immediately after you have finished exercising. Write down the number.
One minute later, take your pulse again and write it down.
Subtract the number for the second pulse check from the number for the first pulse check. This number is your Recovery Heart Rate. The greater the number, the better shape you are in!
