While many of these programs are well-researched and developed for coaching certifications, they rarely teach a well-thought-out implementation framework from which to apply the for individual who are ready to make positive change to their health and wellness.
The point at which science and theory meet real-life training in the gym usually falls apart because the science is hard to implement and tedious to track.
This causes the well-intentioned certified personal trainers and coaches to look online or to the latest IG post for programming inspiration. The lack of programming effort is made worse due to the fact there is often no system in place to properly classify and progress an individual through the various phases of their needs or their goals and objectives.
No assessments, no periodization, just random starting points, no clear path, no framework. This is all made worse by the trend over the past decade to combine individuals from disparate health and fitness backgrounds all together in one class session.
