I am currently using Suunto m4/m5 heart rate monitors with my clients. One feature they don’t have is the ability to track the time spent in each heart rate zone. I was wondering if some personal trainers out there have a solution they really like for tracking data such as this.
I prefer the Garmin Forerunner 910XT. It has GPS, free tracking program that is wireless, can be used by swimmers, cyclists and runners. Top of the line heart rate & GPS watch.
