Wide vs. Narrow Dips

I’ve been doing narrow dips for a couple of months as my main upper-body push. The result is: good triceps + some front delts stimulation. Chest almost non-existant.

I can’t do wide dips at the gym, so I sometimes do them at the garage, between to desk (the grip changes cause I have to grab the edges of the desks). Its harder and hits the pecs nicely but it feels strange with my shoulders and kind of kills my wrists.
