<b>Maximum Heart Rate (HRmax)</b>

<div align=left>This is the highest number of times your heart can beat in one minute.</div>
<div align=left><b>Measuring HRmax</b></div>
<div align=left>Ask your doctor for a cardiac stress test (sometimes called a treadmill test or exercise test). This is the most accurate way of measuring your HRmax, and requires you to exercise while being monitored by an ECG.</div>
<div align=left><b>Formulas for HRmax</b></div>
<div align=left>A 2002 study of 43 different formulae for HRmax concluded that <b>no "acceptable" formula currently existed.</b> Example: all formulas give the same or close HRmax for members of one olympic rowing tream (all team members are in their 20s). Their actual HRmax varies from 160 to 220. The formula deemed least objectionable was: HRmax = 205.8 − (0.685 × age). This formula is used in GymGoal.</div>
<div align=left><b>Measuring HRmax at home</b><br>(get clearance from doctor first)</div>
<div align=left>Begin by warming up thoroughly on a stationary bike or treadmill with a heart rate monitor built in. Increase your effort every minute for 5 or more minutes until you are unable to run or ride any faster. Once you have reached this point, put all of your energy into the exercise for a full 15 to 20 seconds. Stop peddling or running, and then immediately check your heart rate for a full 60 seconds. For the most accurate results, repeat this test several times on different days.</div>
