With a PT or on your own. Your PT logs the sessions you do together, you log everything else, and you keep the full history.

The 141 story

141kg. One for one, keep going.

One for one: trainer and client, training from one shared record. You log, they follow, and you both see the same progress. The data belongs to both of you. While your subscription is active, either of you can export the full history whenever you want. Most platforms lock people out. 141kg keeps it open. Train, track, progress. One for one, keep going.

Why 141kg

Professional tracking, without the premium price

Most platforms add charges as you grow: branding, extra clients, premium tiers, and your data often stays locked to their app. 141kg keeps it simple. Focused progress tracking for PTs and clients, with your full history yours to export.
