Good to have low resting heart rate (although this guy has to be a new fellow in the training business not to have seen that). Also if it recovers from exercise fast. That is, after you get it up over 150, which is a reasonable training rate for person your age, then when you stop, how fast does it slow down again. Back when I started doing the bicycle thing it took several minutes for my heart rate to go down again when I stopped, but over time, it went down to less than a minute.

How much fuel you burn (metabolism) has also to do with endocrine system. As you get older, or diet repeatedly, that gets more efficient too. Horribly complicated tho. Adrenals, pituitary, all that.

Must go dig out my heart monitor and take it walking. It is more fun than pedometer.
