Features

Built for decades,
not just tomorrow.

Daily Readiness

Know when to push.
Know when to hold.

Every morning, Zenshin reads your HRV, resting heart rate, and sleep from Apple Health and computes a calm readiness score from 0–100. When you're primed, your session reflects it. When recovery is low, it gently adjusts — fewer sets, lighter targets, no judgment.

No cloud. No guessing. Everything runs on your device.

Whole-Body Load

Your runs
count too.

Most gym apps ignore everything outside the gym. Zenshin doesn't. It counts your runs, rides, and walks alongside your lifts — then tracks the acute:chronic workload ratio so you can see when total strain is climbing before you feel it in your joints.

One picture of your whole training load. Every kind of movement, unified.

Intelligent Deloads

Rest is part
of the plan.

Zenshin watches your readiness trend and workload over time. When the pattern suggests fatigue is building, it quietly recommends a lighter week — before you feel the need for one. No nagging, no punishment, just a calm nudge at the right moment.

Training consistently for years beats training hard for months.

Sustainable by Design

Built for the
next 40 years.

Joint-friendly progression, longevity training intent, and a calm double-progression model — adding reps before adding weight. No streaks, no shaming, no noise. An Apple Watch companion for glancing at readiness and managing rest timers from your wrist.

The goal isn't next week's PR. It's still lifting, comfortably, at 70.
