I’ve never been one for distance running, but I do love my sprints. As a soldier I’m required to run 2 miles every so often for fitness tests, and now and again I have to take the guys out on a 4+ mile run. One of the guys swears that a heart rate monitor has reduced his times significantly by making him run in his target heart rate zone. Personally, I don’t see how a light to medium jog can do anything for me, but I’m still curoius as to the cario endurance benefits.
Any insight on these monitors? Any benefit at all to target HR cardio? Or is this a general waste of time?
