OK well if you've built a solid base from powerlifting first you should be gtg.. Honestly I don't recommend doing any pro bodybuilders 'training programs' it had been released that most of the training programs you'd see from pros in some magazines were just a sham to make you think they were killing it for hours on end..typically not the case. You wanna put on some size, stimulate the muscle with some heavy ass weight. Intensity is key, and take the training to absolute failure including the negative portion, I believe that's most important. Make sure to hit your compound lifts, opt for barbells and dumbbells over machines
