Recovery signals that change your training.
Sleep quality drops during a hard block. Oak flags the tradeoff before it costs you progress. You can grind through poor sleep for a while. Eventually, performance pays the price. The question is whether you see it coming.
Recovery is training data
Sleep, HRV, and resting heart rate tell you how much stress your body can handle. Training apps that ignore recovery leave you guessing when to deload or reduce volume.
Oak reads recovery alongside workload
During hard training blocks, Oak monitors sleep and recovery trends from Apple Health. When recovery drops while load stays high, the coach recommends adjustments—more recovery, lower volume, or strategic deloads.
No wasted effort
Pushing through when recovery is compromised is not discipline. It is inefficiency. Oak helps you train hard when you can and recover when you should.
