Stack is a fatigue tracking app designed to help you optimize your training based on how your body actually responds to impulse.

Balancing fatigue and performance is delicate and highly individual. Some athletes perform best with a high-intensity, low-frequency approach. Others respond better to more moderate training performed consistently. Most people fall somewhere in between.

Understanding where you sit on that spectrum is critical to getting to most out of your training. Stack helps you monitor load, manage recovery, and reduce the risk of overtraining or undertraining.

If you already know what works for you, Stack helps you train with confidence and purpose. If you don’t, Stack helps you get the most out of your training!
