Weak Right Arm During Overhead Press/Bench

I noticed after a couple months of Triumvirate, that I am weak on my right side while doing my overhead press. What could I do to even my arms out? I figured that my dumbell assistance work would do it, but I haven’t seen any improvement on it other than just strength overall

Do single arm dumbbell presses. Bring your weights down on your mains sets and assistance and focus on using your right side, mind muscle connection isn’t bullshit strength athletes want it to be, there’s some truth to it. Do unilateral work for your back too
