Nope! Its the recovery rate that is the good indicator. My wife has the lowest resting heart rate I have ever come across (excuse the pun), but she can't run for a toffee!
Seriously though, a lower resting pulse is a good indication of your potential!
You get a lower resting heart rate when your left ventricle (part of the heart) increases in size. This is due to the heart being a muscle and it gets bigger with exercise. As the heart gets bigger it is able to pump more blood around the body with each beat. That's why a fit bloke seems to be cruising, it's because his heart isn't having to work as hard as the unfit bloke whose heart is going like the clappers. Miguel Indurain (a cyclist) had a resting HR of about 28 beats per minute (BPM). True rest is first thing in the morning before you get out of bed. A fit person will have a resting HR of less than 40.
