it seems that i get stuck more at my mid-point i think and locking out, what about bands and chains?

If you don't have them, then don't worry about it.

Go to a lumber yard and get some 2x6's cut 19" or so long. Use some wood screws or some duct tape and make a 3 board and a 4 board. There's 2 exercises right there.

Floor presses would address the problem right away. Try doing a few sets of 3-5 reps on the floor. You'll notice your triceps/shoulders getting smoked. :D

Start hammering away at your problem: TRICEPS!

Look into the powerlifting exercise description thread and pick out a handful of triceps exercises to work on.

Reread: How to Increase Bench

recently i have tryed some floor presses but on the day i bench should i do both regular bench and lets say incline bench with floor presses or should i just do floor presses later on in the week?

Hard to say without seeing your entire routine. Post your entire routine and I can certainly fix some shit for you.

well i usually bench twice a week but its ok ill just do some after benching or just alternate it in
