Keep rotating diff lifts incline, decline, flat, close grip, wide grip, reverse grip, do dumbbells and also barbell. dips are awesome, esp. weighted dips. I usually do barbell 1st and then do dumbells w/bands all have helped. I'd also suggest(if u don't already) Do major compound movements like deadlifts, rackpulls, squats because that will help increase u're test production and size overall. Keep u're calories and protein up and don't overtrain. I do chest 1 time a wk and for me that is plenty.
Oh...another thing u can do is negatives... like bench heavy but bring it down real slow and explode up.
