i dont have a pulley or a crossover and none of the fancy machines. i prefer free weights. so any suggestions would be welcome and met with a thank. how do i make a 4 day split with what i have? i know i'm probably maybe over doing it, but if you can help take some away and add some if you feel like it. i just want to break it up somewhat. my main goal is to put on muscle and lose the stomach flab, and look leaner.
thank you for any help advice given.

I think it's a good idea you've chosen to change things up, because that routine looks like it's a little too much. If you're going to do a 4 day routine, I would suggest and upper/lower split. There are a bunch of routines posted on these boards already and you could just do a search. Whatever you choose to do, I highly recommend dropping a lot of your isolation movements and really concentrating on the big compound lifts like squats, deadlifts, rows, bench presses...(and their variations).
