Lactate threshold training: no longer limited to the pros.

It’s all about knowing your limits - when to push those limits and when to pull back, so that ultimately you can break them. Lactate threshold training is the science of measuring your limits over time, then continually adjusting intensities so that you’re always training at the optimal level. Which moves your body’s threshold higher and higher over time, until you surpass previous limits - and break personal records.

This training method has been used by elite athletes, Olympians and professional coaches for more than forty years. For the first time ever, it’s now achievable through a simple, wearable device.

Using LED lights to “look” into your muscle, BSXinsight analyzes your unique biosignals to identify both your lactate threshold and personalized training zones. It’s as accurate as previous blood-based measurements, and it uses the same technology that experts and clinics use – with the added benefits of being wearable, ANT+ compatible and immediately actionable. Finally, you’ll always know how your body is responding to training, from the inside out.
