Well Madcow2's 5x5 variation is pretty basic and concentrates on the squat, bench and deadlift. It also throws in rows, chins, and military to round it out.
It's not strictly a powerlifting program, but considering it only uses 5x5 and 3x3 rep ranges it stays in the power area pretty damn well if you ask me.
In 5 weeks I've put on 8lbs as I'm on the last day of the deloading phase and I have 4 weeks to go on the intensity phase where I'll probably put on another 5lbs easy. My arms have grown 3/8". I have no doubt they'll be 17" by the end of the next 4 weeks at a bodyweight of 225lbs or more.
This is BY FAR the best program I have ever used for building strength and size and I've been training off and on for 10 years and pretty much tried it all.
I will not go back to regular super-compensation style workouts. Straight up dual-factor for me from here on out!
