Zyra Workouts

Fast, honest workout logging. Zyra Workouts is a workout logger that respects your time and your data — log sets in seconds, see real progress on a dashboard built from your own training, and keep every byte of your data yours. Offline-first, no ads, no third-party trackers.

Log fast

• A keypad built for the gym: sets, reps, weight in seconds
• Warm-ups, drop sets, failure sets, left/right sides, partials
• Supersets, rest timer with presets, per-exercise rest overrides
• Plate math that knows which plates your gym actually has

See real progress

• Dashboard cards built from your training — volume, muscle balance, consistency
• Muscle-group drill-downs and per-exercise history
• Body-weight log with trends; weigh-in and training streaks
• Optional Apple Health integration shows your real activity and heart data (read-only — Zyra never writes to Health; native iOS build only, not the web app)

Yours, offline

• Works fully offline; no account required
• Optional Zyra account backs up your workouts and restores them on a new device
• Delete your account (and all synced data) in the app, any time
• No ads. No third-party trackers or analytics SDKs. Your training data is never sold.

Train on your terms

• Start freestyle, or seed a session from workout templates
• Custom exercises with muscle mapping
• Menstrual-cycle logging with training-load overlays, if you want it
• Smart Progression suggests your next sets from your own history — training guidance, never medical advice

Tools that use the same math

The formulas and catalog data behind Zyra Workouts are published on this site as free, browser-only tools. Each row names the app module the page is built from.

• 1RM calculatorlib/e1rm.ts

  The estimated one-rep max the app shows per set — Brzycki to 12 reps, Epley above — with the rep-max table.

• Plate calculatorlib/plates.ts

  Plates per side from your own inventory and bar, the same decomposition the in-app plate math uses.

• RIR / RPE converterlib/rir.ts

  Reps in reserve to rate of perceived exertion and back, with the clamps the logger applies.

• Weekly sets calculatorfeatures/dashboard/compute.ts

  Working sets per muscle for a planned week against the dashboard landmarks, secondary work counting half, plus the balance score.

• Exercise librarydata/exercises.json

  All 61 catalog exercises: muscles, equipment, default rest, rep and RIR targets by goal, progression step, alternatives.

• Programsfeatures/program/generate.ts

  Six generated templates and a live generator running the Smart Generation rules — labelled as templates, not prescriptions.
