Me---being older than dirt LOL...And retired pro bodybuilder....At 46 it is about not getting injured, let the younger guys "bulk up" I like volume as well, also drop sets, giant sets, pre-exhgaust...Always changing it after 6-8 weeks...Yeah some days I will do heavy (relevant) 4-5-6-7 reps but after a good warm up and maybe towards the middle-end of my routine...
My last chest workout/Sunday was---BodyMaster vertical chest press/wide 2x10 2x12, Incline db 2x8 x6, Incline Hammer 2x10 x8 super set with weighted dips 2x12 x15 and Cable x-over 15 from top 15 from bottom 2x.
All my training is done in my home-basement gym.
