Searching for “Row” with the Dumbbell equipment filter selected shows only two exercises. It seems there are several missing:
  • One-Arm Dumbbell Row
  • Bent-Over Dumbbell Row
  • Dumbbell Incline Row
  • Pendlay Row
  • Gorilla Row
  • Renegade Row (actually in the DB, but listed as a bodyweight exercise; it's more commonly done with dumbbells)
