Find a steady pulse or beat
Start a timer for 15 seconds
Count the number of beats you feel or hear in those 15 seconds
Multiply that number by 4 to get beats per minute
Use a 30-second count and multiply by 2 for a more accurate result
Use a full 60-second count for the most accurate result
Repeat the count if the rhythm is irregular
Use a BPM app, metronome, or heart rate monitor if needed
