Mr Quack Quack, I have a comment about the splits in your schedule. You have one day for shoulders, for example, and one day for arms, etc. My concern is when you said you have one day for legs and you have a goal of surpassing 600 pounds on the incline leg press.
Here's my concern. Leg muscles, being some of the biggest in the body, can create a very demanding workout. I mean, if you do all leg areas in one day: glutes, quads, hamstrings, calves, inner and outer thighs--you will have one exhausting workout if you are working on heavy weights such as you mention.
I see lots of guys in the gym that NEVER plate up a leg press machine to 600 pounds or even close. If you are working that heavy, you will really feel a total leg workout if you do it all in one day. Why? Because if you want to achieve a 600 pound leg press, you will also need to do very heavy hamstring curls in order not to develop imbalances between front and back. Too, you should be doing squats and calf raises, so as not to develop bulgey quads with weak hamstrings and smallish glutes behind and weak calves below.
Doing all that heavy work to keep muscle balance in one day will leave you weak, sore and tired. I dare say, it can damage joints and tendons, too. Heavy leg presses can wreak havoc on your lower back and your knees, especially if your technique isn't perfect and you haven't strengthened your other muscles to match the strength you want in your leg presses.
My advice would be to divide up your leg workout and add it to rest of the week. Maybe do different leg parts on three days of the week along with the upper body part you set for that day.
I don't know what your present strength is in regard to leg presses, squats, chest presses or any other criteria. I do say go easy and slow. You have set out a very ambitious program. You don't want to overtrain or, even worse, sustain an injury.
I wish someone who actually knows you at the gym could give you some advice based on your present capacity. That person could help set up a graduated program for you so you don't burn out or injure yourself.
By the way I am by no means trying to dissuade you or discourage you from achieving the goals you have set out. I'm just trying to help you MEET those gaols in a safe and timely manner. Good luck. Please let us know when you shoot past that 600 pound leg press and let us know how you did it. I'll be very proud of you.
