As endurance athletes we know how to suffer. We know how to grind out back-to-back-to-back days of training sessions. But does that mean it’s the right thing to do? How many of us know if our body is ready to absorb the training on any given day?

Whether it’s being smarter about how we train, making a better effort to get more sleep, or simply thinking more about our body’s overall wellness, we’re all looking for ways to improve our health.

While most wearables only provide insight to calories and heart rate, WHOOP is a fitness tracker that goes next-level into the insight it provides.

WHOOP tracks how strenuous your day and training is in real-time, the performance of your sleep, and how recovered your body is when you wake up.

If you’re looking for a wearable tracker this year look no further.
