This 4-week routine is based on a “classic style” of bodybuilding, pulling from the training methods utilized by many of the old-school bodybuilders from the 70s-90s. For any given exercise, rep ranges will be between 8 and 30 and the number of sets will always be below 5. Light-moderate weight will be the main focus, with some heavy exercises mixed in. The focus of this routine will be on stretching the muscle fibers, squeezing and pumping blood into the muscle during each rep, and utilizing partial and full pause reps. Each muscle group will be targeted once a week with the exception of legs, which will be split into two days: an anterior quad-dominant day, and a posterior hamstring and glute-dominant day. Expect long workouts with attention to detail in every rep to maximize muscle development and taxation.
