The three-minute step test is one of the simplest methods. With this test, you use a 12-inch step and a metronome, stopwatch, or metronome app for your mobile phone. You step up and down to the metronome for three minutes, then sit down and take your heart rate for one full minute, counting each beat. Become a personal trainer at NPTI Tampa in our May semester.
