These organic changes have been led by all within the RKC, not just by Pavel. I can think of one particular example of this evolution. In one of his first books, Power to the People, Pavel wrote about a moderate intensity, high frequency program that led to big strength gains. Power to the People turned the strength-training world upside down when it first came out. It was so revolutionary compared to the pump and blitz bodybuilding style that was in vogue.
Then, the program received a further update in Beyond Bodybuilding.The core exercises of a push and a pull for two sets of five repetitions became three to five exercises, performed three to five days per week, for three to five sets of three to five reps. Easy Strength anyone?
