Where are you bringing the bar down? High on the chest? Middle chest? Low chest? Top of the abs?
Each of those places changes the emphasis as far as muscle recruitment: more or less triceps/anterior deltoids/upper chest/lower chest.
Another consideration is that the stabilizing muscles are holding things back, so you may want to consider working with dumbbell bench press for a bit until everything has settled down into a good groove. It will be pretty shaky the first few times you do it.
Also, how is your back work? Rows? Deadlifts? Pullups? Your back can hold back your bench press too. (Based on your OHP numbers, it sounds like your lower back is fine, but it's possible your upper back needs more work to help your bench.)
Just some points for exploration; there's plenty of content on this site.
Maybe helpful: There's a video series called "So you think you can bench" that discusses form pointers from a more powerlifting standpoint.[/quote]
Thanks for the response.
I usually try and bring the bar down on the top of my abs as I'm just following what I've seen powerlifters do. I recall injuring my shoulder a long time ago bringing the bar down high on my chest so I avoid that.
I usually do incline db press with 20kg db's for 4x8. I feel pretty comfortable doing this as my shoulders seem to do a lot of the work.
My upper back is my strongest bodypart, I tried BB rows for the first time and comfortably rowed with 100kg x 5.
I'll check out the video, thanks man.
