Following the last article on cardiac arrhythmias, a reader wrote in with a question which I think many recreational athletes may also harbor. I thought it would be helpful to answer it as a mini topic.
"...do you think a weekend warrior like me should invest the $150 or so to have a LT and fuel efficiency test? I don't really compete, but am curious about training heart rates. I just use general guidelines and a monitor. I am also not worried at all that I am overdoing it! Your opinion is respected and appreciated." - Ralph
