Garmin 110....looks like a watch....you can get it with a heart rate monitor.
I run 30 miles a week and cycle 100 miles a week(when warm out.)
Calories count works and is accurate.
Calories in....Calories out. Its a simple formula and the one most true and telling for weight loss.
Knowing your calories(burned and intake) and owning a scale are the two most important factors in weight control.
