Hey Mick I haven't seen that site before, i'll have to give it a look.
I've always been fan of bodybuilding - my first gym was a hardcore bodybuilding gym run by an ex-Mr Australia - so i was raised on traditional bodybuilding splits.
These days I very much enjoy making strength gains, but my bread and butter is still the 'assistance' work I do afterwards, which is effectively a BB split.
Personally I think training like a BB is great - it feels good, the higher reps and low rest is pretty good for the heart and fitness in general, and you get to be big and look good. It's also easier to have a more normal diet, because you burn so many calories with the higher work rate than strength or powerlifting.
Obviously there are also benefits to strength training, or we wouldn't do it.
You are working all your muscles with the big compund lifts - you're just not isolating them, which accounts for the different feeling obviously.
If you want a good BB split there's a heap out there, and most guys will tell you something different. You can get some of the effect with 3 days a week, but traditionally BB'ers will train at least 5 or 6 days.
Something like:
Chest / Shoulders / Tri's -- Mon, Thurs
Quads / Hams / Calves -- Tues, Fri
Back / Bi's -- Wed, Sat
In my opinion and experience, hitting each body part with a reduced volume but increased frequency is very effective.
I don't currently train like this for various reasons but when I did I was at my biggest, leanest and most aestheticly pleasing.
For combined strength and size gains I reckon you can't go past trying 5/3/1. It's what I use now. 4 days a week, do your major lift to begin, then follow up with a traditional BB split.
Example:
Mon- Bench 5/3/1, Dips, Dumbell bench, Dumbell Flies, Skullcrushers
Tues- Deadlift 5/3/1, Chins, Dumbell rows, hyperextensions
Thurs- Squats 5/3/1, SLDL, Front squats, calf raises
Fri- Shoulders and Bi's.
End of the day you need to understand what you're programing and train however works well for you.
