can benching too often, and doing no lats workout cause shoulder pain due to muscle imbalance?
yes.
benching in an of itself can cause you massive shoulder problems.
I actually have a minor tear in my rotator cuff from bench press. I have not been able to bench properly in just over 2 months, and I may never fully recovery as a result. I stick to only dumbbells now.
Bench press is a deadly exercise for the shoulders, especially if they are not as strong as your chest.
To prevent this, you need to train shoulders properly, and pay extra attention to the rotator cuff....google these exercises, there are a ton of them, and they are ALL good. Just pick the ones you like the best and train it on chest days as well as shoulder days.
Also, if you feel pain in the shoulders while benching, STOP IMMEDIATELY.
