DB Bench Press Form?

Hey guys,
Is it crucial to push it in a triangular shaped way? because I find that it is easier to press it in a straight line or does that relay on the triceps too much? by the way, how do you guys know when you are going deep enough?


If your pecs hurt like **** you know you’re doing it right. You are deep enough when the dumbell hit your shoulder/pec. I like to go a litte deaper than that bacause it hit my pecs better.

I always do them with a neutral grip and lower until the DB touch mu chest, then I pause and push it back up. That’s what works the best without fucking my shoulders.
