I don't think changing to incline bench for flat bench would hinder pectoral development, but probably enhance it which is what I think SR is probably after being the ladies man that he is
I agree to try to keep compound exercises pretty much your staple while "changing up" the exercises for other muscles. I wasn't suggesting to do leg extensions in place of squats by any means. By maybe sometime you want to to front shoulder presses instead of rear shoulder presses, maybe sometime you want to do arnolds for a bit on shoulder day instead of side lat, maybe you want to switch from DB's to a plate for front row, or use the a cable machine for it. Change from upright row on the smith machine to ropes on the cable machine or use a reg barbell. Change from preacher curl with curl bar to dumbbells on the preacher curl, do curls on that cable, do hammer curls instead of palms in. Try some supersets, try some drop sets which can be done with compound excercises as well. I could go on and on, but my point it keep it fresh, keep it fun, work hard and keep coming back while of course using compound movements supplemented with lifts for the smaller muscle groups.
