Your plan bends to
your life — not the
other way around.
Rex knows your history, your goals, and how today actually went. Slept badly? Missed a session? Legs still trashed from Sunday's long run? Tomorrow's workout reshapes itself — automatically, with the reasoning shown.
Context-aware, not calendar-blind
Reads HRV, sleep, load and recent runs before every adjustment.
Always explains the why
Every change comes with Rex's reasoning, so you stay in control.

including what
fuels it.
Training is only half the story. Log meals in seconds and Rex folds nutrition into the same view as your load and recovery — so fueling, training, and rest finally line up.
Fuel that matches your load
Macro targets shift with your training week, not a fixed number.
One picture, not three apps
Nutrition, recovery and training in a single timeline.
