This lactate sensor by BSXinsight is your opportunity to maximize your workout. It measures not only how hard your body is working via muscle oxygenation but also your ideal training zones through endurance tests. This small, lightweight device is held securely against your calf with the sleeve, ensuring that you receive the most accurate results. These precise measurements are then sent to your phone to keep you up to date on your fitness.

  • Secures BSXinsight to your calf muscle as you train to ensure proper positioning and accuracy.
  • Weighs in at only 20 grams (approx 4 US quarters) and is about the size of a heart rate monitor (78mm x 37mm x 14mm)
  • Optimized for over 8 hours of continuous run time—long enough for every workout.
  • New light blocking technology allows you to use indoors and outdoors.
  • Immediately sends training data to the cloud via your phone for immediate results.
