A training log that adapts to you

Trenx reads your recovery — sleep, wellbeing, heart rate — and adjusts today's workout: sets, load, RPE. The plan stays yours; the decisions get informed.

How it works

Three steps between you and the right workout

01

A 20-second morning check-in

Sleep, energy, soreness — three sliders. Or data from Whoop; Garmin, Polar and other wearables via Health Connect — coming soon.

02

Readiness score

Trenx compares today's signals against your personal baseline and scores your readiness to train.

03

An adjusted workout

Suggestions on top of your plan: fewer sets on a heavy day, a deload when fatigue builds up. Accepting them is up to you.

Your plan 4×5 · RPE 8
↳ suggested 3×5 · RPE 7
Wearable devices

Readiness is computed from your data, not gut feel

Connect a wearable and the morning check-in fills itself: sleep, resting heart rate and HRV feed straight into your readiness score. No device? The three sliders work by hand.
