Lactate, Live.

Train Smarter. Perform Better.

Continuous lactate data, captured in real time for up to 7 days.
Turn every signal into a smarter way to train, recover, and perform.

Continuous Lactate Monitoring

  • Train in the Right Zone

    Identify when intensity moves through aerobic and threshold ranges.

  • Know When to Push

    See lactate accumulation in real time rather than relying only on heart rate or perceived exertion.

  • Optimize Intervals

    Understand how quickly lactate rises during hard efforts and clears during recovery.

  • Personalize Training

    Establish an individual lactate profile and track changes as fitness improves.

  • Improve Recovery

    Monitor lactate clearance after intense exercise.

  • Avoid Overtraining

    Potentially identify when the body's response to a given workload is changing.

  • Actionable Data

    Connect workload, heart rate, and lactate to understand what is actually happening inside the body.
