Does anyone else use a Garmin Forerunner with Firstbeat heartrate Technology to measure calorie expenditure?
Or any other HRM to measure their workouts? If so what kind of numbers are you showing for HIIT training, Crossfit, etc?
I have a 305. I sent into a firstbeat place in DC, and they told me the 305 wasn't capable of "sophisticated calorie configuration"
I used to use my garmin heart rate monitor a lot -- I used to do a lot of cardio -- to ensure my tempo runs were above 85% Max and my long runs were below 70% Max. I could typically get above 95% Max on sprints or in races.
