You seem to be working out your chest a lot....and your legs a lot too... Try doing this
Day 1(Monday, Friday)- Chest(Bench Press, Incline Press, Dips), Triceps(Skull crushers, tricep pulldowns), and Shoulders(Lateral Shoulder Raise, and Shoulder Press)
Day 2(Tuesday, Thursday)- Back(Seated Row, 1 arm DB Row, Lat Pulldown), Biceps(Preacher Curls), Forearms(Wrist Curls)
Day 3(Wednesday, Saturday)- Legs(Squat[MOST IMPORTANT], Leg Press, Quad lifts, Hamstring Curls, Calf Raises), Abs(Weighted Crunches, Hanging leg Raise, Decline Ab crunches)
Day 4(Sunday)- Rest
If you are aiming for more muscle, try to avoid doing a lot of cardio. If you want strength, then try for 8 reps, 3-4 sets. This is the workout I do, and it avoids you over-working a muscle, and gives enough rest to get stronger. I would advise a Whey Protein, because it's good for strength gains. And stick with the weight/rep change, because it DOES shock your muscle into growth, but try to do it at random times. If you don't know what you're doing that day, neither will your body
