In the past decade, there has been a significant shift in the approach to coaching in the field of bodybuilding. Initially, high-level athletes primarily focused on having a supplement coach to enhance their performance. Over time, the importance of a diet coach became apparent, as diet and supplements are closely linked in professional bodybuilding. More recently, the trend has moved towards formalizing training with the help of a training coach. This shift is based on the understanding that scientific insights can greatly inform training practices. There are two main approaches to training: one that focuses on personal preference and enjoyment, and another that emphasizes doing what is necessary to achieve the best possible results. The latter approach is becoming more prevalent as athletes seek to optimize their performance through scientifically informed training regimens.
