Here is what I found works best for me and most of the people that train with me
Day 1 Legs (quad focus) (HEAVY SQUATS)
Day 2 Chest, Biceps ( flat bench work)
Day 3 OFF (cardio, calves,abbs)
Day 4 Back (pull ups, bent overs and heavy shrugs)
Day 5 Shoulders, Tri (standing over head press)
Day 6 OFF
Day 7 Legs (ham focus) (various machine and LIGHT stiff legs)
Day 8 Chest, biceps (incline dumbell work)
Day 9 Off (cardio ,calves, abbs)
Day 10 Back ( Dead lifts)
Day 11 off (cardio , forearms)
Day 12 off
Next leg day is no squats and Day 4 has deads again, and depending on how I feel I may or may not do squats again day 7
Each training day is built around a Core exercise I use for that muscle group. We do 2 or 3 exercises for that each body part, but the core exercise is the climax of the workout , I consider the other exercises a just build up for those 4 or 5 "balls to the wall " CORE sets.
My workouts last about 60 to 75 minutes.
Now to answer Hanibal, I have no idea what general physical preparedness is but at 5'9 and a hard 260lbs I think I'm prepared for whatever comes my way.
You can't compare a single small muscle like calves to a HUGE muscle group like back, You will easily overtrain doing too many compound movements in a certain time frame, this I guarantee. I would rather undertrain and get little growth than overtrain and get none.
I'm not and athlete nor do I care to ever become good at any exercise I do, in fact I want to my to as inefficient as possible when performing an exercise so I can get maximum muscle gain from it.
Squating 3 times a week the Iron God way is not only impossible but detrimental and dangerous.
