Dumbbell Rear Delt Fly
The dumbbell rear delt fly is a rear-delt movement for the shoulders (deltoids), done with dumbbells. It also works the upper back (lats and rhomboids). On weyt.ai it counts toward Balance as Shoulders (minimum 6 sets per 30 days) and toward your 12-week strength trend at the weight you log.

How weyt.ai scores it
- Balance: every logged set counts toward the Shoulders 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 a best lift estimate (an estimated one-rep max) per lift, read over 12 weeks on the Strength screen.
- 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.
