Readers of this website who lift will no doubt be familiar with Mark Rippetoe and his Starting Strength program for strength training. Mark has been working in the industry for close to fifty years, and in that time he has built up a small but core business which focuses on searching out and working with truth as opposed to spin or fads. I have read a number of his articles and one thing that I have taken away is how perplexed he is at the success of corporate gyms that push pretty lies. Planet Fitness advertises free pizza with their memberships which is ludicrous on many levels. But still they do well despite people who go to these types of gyms not achieving any gains unless they pop some magic pills.
Mark wrote an article a few months ago on the state of the industry due to the lockdowns imposed by our clueless overlords. He is hopeful that this crisis will cause the failure of the globogyms and that his training programs which actually work for people will prevail.
