First off, you have 1 lower body day and 3 upper body days. If you plan on going four days a week, do an upper/lower split. Also, lose the flyes. You're wasting your time doing flat, incline, and decline. I'd probably try doing one upper body day with concentration on horizontal push/pull and then the next with concentration on vertical push/pull. As for lower body days, you could do emphasis on quads one day and hamstrings the other. A simple way to do it is to just have one upper body day be flat bench, rows, incline or military press, pulldown/chin, biceps and triceps. Do lower reps on the ones you are placing emphasis on that day and higher on the others. So you might do 6-8 for bench and rows, but do 10-12 for military press and pulldowns. Next upper body day you could do 6-8 for military and pulldowns, but do 10-12 for bench and rows. Bicep and tricep work can be higher since they'll be pretty dead from so much pushing and pulling anyway. Even 1-2x12-15 would be good enough.
For lower body it's the same idea. Squat on one day as your main quad movement, and deadlift on another as your main hamstring movement. Add in leg presses, lunges, split squats, leg curls, calves, abs, or w/e.
EDIT - Also, like HN said, take some time to warmup properly.
