Whoop 4.0 Performance Optimisation System

The Whoop 4.0 is the wearable performance system used by more professional athletes than any other wearable technology in the world — from NBA, NFL, and Premier League players to Olympic and world-champion athletes across virtually every sport. Unlike smartwatches that track activity, Whoop is designed exclusively around recovery and readiness: its proprietary algorithm analyses continuous heart rate variability, respiratory rate, skin temperature, and blood oxygen to provide a daily Recovery score and Strain recommendation that tells you precisely how hard you can train today. The subscription-based model provides the hardware free with a monthly coaching plan.

• Continuous HRV, respiratory rate, skin temperature, and SpO2 monitoring
