-Get leaner by inducing a calorie deficit from a combo of reduced diet and/or more physical activity, such as cardio. You have to remove a layer of fat.
-Keep exercises for chest or torso to 9-12 sets max., 3-4 sets per exercise-put greater intensity into less sets by going to failure on most or all sets, especially the last couple of sets for each exercise. 1 minute rest max. between sets.
-Increase training frequency to 2-3 times a week.
-On the last set of each exercise, do a couple of cheats after reaching failure, and tense the muscles at the top of each rep, hold for 2 seconds. In between sets, push your hands together for 3-5 seconds.
-Try alternate exercises or variations of what you're already doing-use dumbbells for flat presses or try weighted pushups. Try dumbbell flys, cable flys or peck deck instead of crossovers.
-Try not locking out at the top of each rep on some workouts, decide if it helps.
-Dips are only one possibility-many find them hard on the shoulders and not particularly effective for chest. Mainly for lower chest; decline flys are another substitute.
