Personally I structure my training like so: 1 main movement for the day (I have 2 bench days, a squat and a deadlift day) that I rotate between mostly either heavy or speedwork usually doubles or triples usually very submaximal, followed by one major accessory movement usually in the 5-8 rep range. For example if it's a squat day, I may do a good morning variation for a few sets. I then basically shift to more bodybuilding style training for the rest of my movement. I don't have a specific number of sets/reps/exercises but I go based on how I am feeling week to week and how my recovery is. Feel great on a day? More volume, heavier weights. Feeling beat up? Get in and out quick.
