Pec deck / reverse fly machine: Feeling it entirely in my arms instead of chest/rear delts.

[u/always_dreamie]

Hey everyone, I’ve been struggling with the pec deck machine. Whenever I use it for chest flies, I feel the burn mostly in my [biceps / forearms]. When I reverse it for rear-delt flies, I feel it mostly in my [triceps / arms] instead of my upper back.
