I read in a magazine about a new study that has just been done that is quite interesting. The researchers did a meta-analysis of 177 studies to determine what were the best protocols for strength training and came to the following conclusions: - the optimum protocol for a beginner is 4 sets per muscle group at 60% of 1 RM 3 times a week. - the optimum for a trained athlete is 4 sets per muscle group at 80% of 1 RM twice a week. - the optimum for an advanced trainee is 4 sets per muscle group at 85% of 1RM twice a week. It's really remarkable isn't it? It goes against the usual belief that the volume has to increase as the trainee becomes more advanced. Frequency should decrease somewhat after the beginner's stage but not much. Do you have any opinion on that? Do you think we can trust that kind of study? Does it correlate to your experience? etc..
