Three surfaces, one glance each
Daily
Your recovery × what the week needs → one readiness call.
Open TodayIt weighs how recovered you are against the volume your week still needs, then gives one call: push, hold, or ease off. No wearable required — it reads what you log.
Input
Add this week’s sets. Volume rolls up live, per muscle.
Open LogPick from a real exercise library and log your sets. Weekly volume totals update instantly for every muscle group, so the picture is always current.
Weekly
Per-muscle volume vs. your ceiling → the fix-this-first list.
Open reportEach muscle’s weekly volume is charted against a recoverable ceiling you set. Whatever is furthest behind rises to the top — an honest weakness scan, not a guess.
Why Eccentryx
The engine reads your logs so the information side of training is free and honest — no gatekeeping, no guessing.
Training knowledge shouldn’t cost what a session with someone costs — it’s information, and information can scale for free. What it can’t replace is a real person cheering you on. So as your own logged progress becomes real and advanced, the plan is to let you help newer lifters the same way someone once helped you — always labeled as a peer, never a substitute for this page’s own honesty or for medical care.
