This is an excerpt from JC's Total Body Transformation by Juan Carlos Santana.
If you are changing the routine because you hit a plateau or are bored, chances are changing the routine is not the issue; lack of planning and hitting the right intensity is. So, changing the routine without changing your focus, intention, perspective, and progressive manipulation of the basics variables will do little to nothing for you. It may entertain you for a few weeks, but in the long run, you will end up with the same issue: Your training will not get you the results you want. If you are a personal trainer and your clients are bored, it's because you are bored, and your clients are reflecting your energy back at you. If you are bored with your routine, then you have to ask the deeper question of why? If you are uniformed, then you have this book, and that will no longer be the case. If someone is bored because they lack knowledge, then that knowledge must be acquired and applied. Otherwise, no workout will get someone out of a rut, and the cycle continues. Ignorance is one of the main reasons the cloud from the past (same thoughtless thinking) is allowed to cast a shadow on the present (stay stuck), and if something does not change (awareness and evolution), the future does not change (you repeat the same mistake again).
