To what extent do people feel the triceps working during chins and dumbbell rows? I'm doing 5/3/1 with the following assistance on Bench day, done as a circuit/superset:

Incline DB Bench
DB rows
Lying Tricep Extensions
Chins (dead hang all the way up to bar-touching-chest)

I figured that the rows and chins would give my triceps a little bit of a break, but after those exercises, I feel like the tris are worked even harder than my biceps or back. Worried that tricep limitations are keeping me from getting enough pulling work on this day. Has anybody had the same experience?
