The Westside Method

The Westside Method is a great program to use to get very strong and powerful. You basically lift 4 days a week. 2 max-effort days and 2 dynamic effort days where you do a lift for speed and sometimes use bands and other tools. On max effort days, you go for PR's be it 1 rep max, 3 rep max, etc. of your main left. You also do a bunch of accessory exercises to bring up weak points. Squats, Deadlifts, and Bench Presses are at the core of what you will train.

It was developed by Westside Barbell in Columbus, Ohio. If you are looking for World Record Holders for Powerlifting contests...chances are they train in that gym:
