Hypertrophy coaching that uses all your data.
For lifters chasing muscle growth who already track training and nutrition but want better decisions, not more guesswork. You hit your sessions and track your food. Progress should follow. When it does not, the issue is usually a mismatch between training stimulus, calorie intake, and recovery—not a lack of discipline.
Why physique progress stalls
Bodybuilding progress depends on training volume, progressive overload, calorie surplus or deficit timing, and sleep. Tracking each in isolation creates blind spots. A hard training block with dropping sleep quality will blunt growth. Calorie drops without adjusted volume can cost muscle.
Oak connects training and nutrition
Oak reads workouts and check-ins you log in the app alongside calories, macros, sleep, and recovery from Apple Health. The coach surfaces when intake and training load are misaligned and adjusts programming based on how your body is actually responding.
Adaptive hypertrophy programs
Static hypertrophy splits do not account for real-world recovery. Oak evolves your program continuously so volume and intensity match what you can recover from and grow from.
