I made great gains in strength by following 5x5, this is what most of the old timers did, and they had great physiquesand were much stroger pound for pound than todays steroid freaks.
I didn't go over 5 reps, doing some exercises 3x3 and others with progressive singles, doing all body exercises for 3 times per week.
Exercises like rack pin benches (setting pins for the top, middle and bottom work well, as do benches off the floor (lying on floor, not bench - arm movement and range of motion restricted, and can't arch back)
- you can up your benc like crazy by doing dumbells one day, partial pressses another and bottom pos bench last. I did 4 exercises each day for a total of 20 sets.
Just do the basics and avoid dumbell raises and the like, minimising the isolation exercises. Add cleans a multitude of presses, squat and press deadlifts, stiff deads, squats - front and back, bent over rows, chins and you'll be laughing. Arms don't need to be done that much, as you are stimulating them with all the presses and pulling exercises - although I did progressive singles for bi's, adding weight and building to a 1 rep max - sore!
However, my current program (I do olympic lifting and powerlifting) is the best one I have done yet. I lift to percentages of my maximum, having adapted a program by Vitaly Popenkov (world champion Russian powerlifter)
The core of the routine is as folllows:
50% 1rm x 5
60% 1rm x 5
65% 1rm x 4
70% 1rm x 4
75% 1rm x 3
80% 1rm x 3
85% 1rm x 2
90% 1rm x 1
95% 1rm x 1
100% 1rm (or just below) x 1
I've been doing the routine for 6 weeks now and I have gained loads of mass, with my weights COMFORTABLY going up 2.5-5kg every week, infact I now have to reassess ny 1rm again because my 1rm has proportionately got stronger than the weight that I have been adding. I am not innexperienced and already am strong - I just can't recommend centering your workout around this ethic highly enough - I think it gives superior results to 5x5.
