how should a good chest workout be constructed?

[big fig]

Start off training upper chest or start with middle/lower?
Should the whole workout be 50% upper chest 50% middle/lower?

What you start out with is up to your preference. I personally like started with middle and then doing upper. But its good to switch them around, like a rotation each time you do chest. It keeps your routine feeling fresh and I find it keeps me from getting bored for longer.

I would suggest you switch it up from week to week. Start one week with Incline; the next week with Decline. You can also switch up between using barbells and dumbbells.

I have never looked at my chest routine by breaking it down 50/50.

Let me ask you; how many times a week do you train chest? What is your routine like?

Incline DB Bench: 3 x 6-8
Flat BB Bench: 3 x 6-8
Incline Cable Crossovers: 2 x 12-15

Do that with biceps or triceps, and you'll be set.
