The Biostrap wristband biosensor uses Infrared LEDs as an optical PPG sensor, which can record a very high-definition pulse; however, movement disrupts the sensor's accuracy and data integrity.

Therefore, Biostrap offers two different external heart rate monitors to record active heart rate and active HRV during activity.

Using one of the Biostrap external HRMs (Chest Strap or Arm Band), you will have access to the following additional data points:

  1. Accurate active caloric expenditure during the workout
  2. Five exercise zones based on heart rate progression displayed during the workout: Warm up, Fat Burning, Cardio, Hardcore Training and Maximum Effort
