RANKED GYM

Every set you log estimates a 1-rep max (Epley formula), which gets divided by your lean body mass to get a strength ratio. That ratio is checked against a threshold table unique to that exercise — bench press, squat, and an isolation machine all have different bands, since they allow different loads.

New PBs — beat your best e1RM on a lift and your ratio jumps, which can push you straight into the next tier or sub-level.

Consistency (the plateau-buster) — every set you log on an exercise, every distinct day you train it, and every PB you've ever hit on it all build a small "grind bonus" (up to +18%) that nudges that exercise's effective ratio upward over time. Stuck at the same weight? You'll still climb sub-levels just by showing up.

Streak & weekly goal — your login/workout streak and hitting your weekly training-day goal add a separate multiplier (up to +25%) to your Overall Rank specifically.

The average tier position across every exercise you've actually logged (unranked lifts don't drag it down), boosted by the streak/consistency multiplier above. Sub-levels I → II → III are even splits within each tier's band, shown as glow intensity on your medallion.
