Ozzy:
1) linear progression program like Texas Method by Rippetoe. Excellent program for general strength gains. Can be used for powerliftng but probably not the best for it. First time through you run the basic lifts several times a week: squat, bench, press, deadlifts, and very few others besides that. After a few cycles under your belt you can begin playing with the program and adjust to keep it working for you or to alter the training goal. You'll be in the gym 3 days a week, you might be able to get a 4th day in but it would not be a taxing day. More like GPP, conditioning work, fluff stuff, stc. A good but tough program.
2) Wendler 5/3/1: good program but progression is too slow for my tastes although there are tricks to speed it up. The average intensities worked are pretty low though. Don't mean to sound like in bashing it as it is a good program but I'm just not a staunch supporter of it and I know the least about it of all the others i mention.
3) westside....enough said. It works and it has the strongest ppl in the world using it but without a knowledgeable team and specialty equipment you won't make the most out of it. It lacks specificity and you rarely do the actual competition lifts outside of a meet. You'd be lifting 4days a week and you could add more time but conditioning wise, rehab/prehab work, MOB work, etc. Not lifting the 5th day.
4) sheiko: one of the winningest coaches in the world and coached some of the best Russian lifters ever. Well best lifters anywhere really lol. Very specific, highly detailed 3-5 days in gym depending in the cycle, and gains in strength will be bad. Good for powerlifting too. Problem is to get the most you'd need sheiko himself to tailor the program but ppl still have great success regardless. A coach is supposed to regulate the programming based on fatigue but we all can't have sheiko lol. One of my top choices for you. You'd be doing a limited variety of lifts, really the competiton lifts and their variants, with a few others thrown in.
5) DAILY UNdulating periodization: similar to what Insertnamehere is running. Very good program and another top choice. Can't go wrong with it. 3-4 lifting days a week, small lift selection but highly specific, good for PLing etc.
6) block periodization another awesome programming philosophy. Great for PL'ing. Great for strength in general too. Will allow you more lift selection and 3-4 days in gym. You go through different blocks of training. Blocks are accumulation phase, transmutation phase, and realization phase. Complicated but another top choice for you.
7) rts style programming like Mike Tuscherer does. Very auto regulatory, allows a lot of freedom. Specificity is there. Great for strength and PL'ing. Very effective.
Sorry I didn't go into as much detail as I wanted to but feel free to ask any questions or look into them more. I'll answer whatever I can. If you need help choosing we'll go from there but think it over and do some digging. If anything pops out at you as "I want to do tbat" let me know and well design something around hat philosophy for you.
