Most apps ignore how you slept. STRAXE reads your recovery and sizes today's lift—heavy when primed, light when fried. Train smarter, not harder. 7-day free trial.
STRAXE is the strength app that trains you to your recovery — not just your calendar.
Most workout apps hand you the same heavy session whether you slept eight hours or four. STRAXE reads your recovery from Apple Health — sleep, HRV, and resting heart rate recorded by your Apple Watch or ring — and sizes today's training to match. Heavier when you're primed. Lighter when you're fried. That's how you get stronger without burning out.
RECOVERY-AWARE SMART WORKOUTS
Every morning STRAXE turns your sleep, HRV, and recent training load into a readiness score, then builds a session that fits it. Primed? Push. Run down? A smarter, lighter day keeps you progressing instead of digging a hole.
Readiness needs an Apple Watch or another wearable that writes sleep and HRV to Apple Health. Everything else in STRAXE works without one.
