Here's the deal... I did my 30minutes of aerobic activity on one of those eliptical running machines today. During the course of that half hour, I found it comppletely impossible to keep my heart rate UNDER 170! Now... is 200-(age) your MAX heart rate, or target heart rate? 200-26=174 which means That I was at this heart rate for the entire workout. Is this good or bad? I'm trying to trim up... not blow up my heart! :)
