The Park in this program of strength training, not circuit-training.Training to 106 working sets requires a minimum of 40-45 warm-up sets. Let each of the 150 sets takes only 2 minutes (which is doubtful). Even in this case 300 minutes=5 hours. In fact, when you consider the rest between heavy exercises and disassembly, and Assembly of training equipment, this time will have to double. Thus, knowing that the Park was trained in this mode for 3 hours, we come to the number of work sets in training in the region of 50 sets. I apologize for the grammatical errors, I'm using the Google translator.
