Determining Your Optimal Heart Rate Zone
There are five basic heart rate target zones. Simply select a zone 
thatmatchesyourpercentofmaximum(%)heartratebasedonthe
fitness goal you want to achieve during a particular exercise. Before 
you can set your %, you first need to determine your maximum 
heart rate. You can use many methods to estimate your maximum 
heart rate. The booklet “Heart Zones
®
 Tools For Success” provides 
excellent procedures and Timex recommends you use one of these 
methodologies. 
However, if you cannot use any of the procedures you might  
consider using the government recommended age-based method. 
Begin with the number 220 and then subtract your age. For 
instance, a 35-year old would begin with 220 and subtract 35 
(herage),whichgivesanestimatedmaximumheartrateof185.
Once you know your maximum heart rate, you can set the zones 
described in the following table.
Zone % Goal Benefit

2 60% to 70% Weight management Lose weight and burn fat
3 70% to 80% Aerobic base building Increase stamina and aerobic endurance
