Tricks of the Trade
I don’t use the rating of perceived exertion scale for my clients because I think that method is better suited to a clinical setting. I have been using Mio watches and a couple of other similar brands for many years. They are inexpensive and easy to use. I use them for fitness assessments, especially when I have my clients do the 1-mile Rockport Fitness Walking test because I need their heart rate and time in order to calculate their aerobic capacity and get the most accurate results.
