Dont forget your cardio. Running burns fat which will reveal more of your underlying muscle.
Incline barbell and hammer machine are good for shape. Flatbench builds mass. Declines isolate the chest more which will build strength.
Also im not sure of your routine but try to pyrimid your weight. For example 12 reps.@warm up weight, 8 repsraise weight and 6 reps at the highest weight you can do six reps with (it helps to have a spotter).
Lastly nutrition is just as important as your exercise, get plenty of lean protien. Hope this helps.
