There is certainly no shortage in the introduction of new exercise regime videos. The usual argument behind the new production is that it's always better than those that were previously produced. One thing that is common amongst these videos is that in most instances the subscribers get bored from them and they become shelf items. The frequency in which new ones are introduced seems to also suggest that they are not that effective as advertised. I am doubting that one will get their money's worth if they but any of these videos.
