Slow down there, good sir. You haven't really told us anything now, have you?
First off, how strong are you right now (Squat/Bench/Deadlift numbers)? How much do you weigh, and how tall are you? What exactly are your goals? ie, do you want to compete in powerlifting?
If you're not really strong, I'd suggest starting with a round of Starting Strength until it doesn't work anymore, then switch to something like the Texas Method, Bill Starr's 5x5 or Jim Wendler's 5/3/1, whichever is the most appealing to your goals and schedule. Also, if you're not that strong yet, 'speed days' aren't that beneficial. The program you laid out looks a lot like a generic BBer program, tons of volume and tons of similar, but slightly different exercises following one another.. and the fact that you seem to want to devote three, reeeeally long days to the bench press and only two very short days to doing hard work (squatting and deadlifting). Where's the progression in strength? You're cycling intensity (for the bench press), but when do you increase the weight you lift? By how much?
If you need to gain weight, lots of milk will take care of that for you.
I hope you get the point. You're overcomplicating and focusing on the wrong things, if you want to start into strength/powerlifting. The squat and deadlifting deserve the same amount of effort as the bench press. A well thought out program someone who knows what they're doing is much better than whatever you on your own will come up with at this stage in your development. Hell, you could even go the SUPER RIDICULOUSLY SIMPLE route, like Pavel's 80/20 Powerlifting routine and make great gains in strength for powerlifting for a long time. It's 5 days per week too, cycling intensity in a smart way, and a clear path of progression each week...
Here's some links:
- Invaluable for description of properly performing the big 5 lifts, as well as containing the basic program, daily linear progression.
Practical Programming for Strength Training
- Easy to understand description of basic principles of programming for strength training from novice through advanced stages of development.
Jim Wendlers 5/3/1 Manual
- Great program, stresses simplicity in a four day a week strength/powerlifting oriented split.
Pavel's 80/20 Powerlifting
- Full article detailing the super simplistic program, weekly linear periodization geared very specifically for powerlifting.
Modified Version of Bill Starr's 5x5
- Another good weekly linear periodization oriented towards building the powerlifts.
EDIT: It's a good to note, all of these are 3 days a week, except 5/3/1 which can be 4 or 3 or 2, and 80/20 which is 5 or 4 or 3 (but really low volume... only the powerlifts and stretching).
