It might just mean that you need to work a little bit more on your shoulder mobility. If you aren't already, do the warm-ups in the video below before EVERY workout session. And for now with your dips, only goes as low as your mobility will allow (without pain), as you work on improving your mobility.

It may be cause of my shoulder mobility but i only think that it's cause of shoulder fatigue since its a push day and dips is one of my last exercises. I was thinking about switching the chest dip with 5 sets bench press, 3 sets decline and 3 sets incline chest fly. I'm trying to minimise the amount of exercises and smash them with many sets.

Yeah shoulder fatigue might be playing a part too. But definitely start working on mobility more if you aren't already. You can play around with the exercises if you like and you might find something that works better for you - it's good that you are minimizing your exercises and hitting them with more sets! Maybe even do 5 sets for each of the 3 exercises for 15 sets total?

Sure you're right!

Awesome man! See how that goes! Still try to improve the shoulder mobility with dips while you're at it if you can 😁 

Definitely XD having healthy shoulders will help me in more than just dips

That's right! Keep up the #GokuGains bro!

Haha yes!
