How weyt.ai scores it

  • Balance: every logged set counts toward the Triceps group, which needs at least 6 sets per 30 days for full credit.
  • Strength: counts as a lift. Your best working set each session feeds an estimated one-rep max (e1RM) per lift, read over 12 weeks on the STRENGTH and LIFTS cards.
  • Routine: any session that includes it counts toward your weekly target, the 4-week consistency window and your streak.

Scoring is plain arithmetic, not AI: the same sets always give the same result. Read the method on the about page.
