Maximal heart rate can be accurately measured by performing a maximal effort test on a running track or stationary ergometer until volitional exhaustion.

“The classic would be to go out to a local high school or running track and run a 400-meter or 400-yard loop one time around as hard as you can. You're gonna pretty much get to your maximal heart rate by the end. Or if you're on a bike, a stationary ergometer, just ride at higher and higher intensities. So you're increasing the watt. Every one minute, you're putting it up 10 or 20 watts until you can't go anymore. You're gonna be able to measure your individual maximal heart rate, whether you palpate that, whether you're using the hand, or whether you have a chest strap or your monitor on.”
