Interesting Post! You are totally right, there are many training programs out there and the usual person looking for a training plan will benefit from most programs. In other words, consistency is key! However, my biggest concern with online training programs has always been the assessment. In my opinion, it is important to check for possible asymmetries and dysbalances before you design a suitable program. Doing such assessments online is quite challenging. That's why I believe high-quality​ personal training and coaching is better done offline.
