We have a policy that no members are allowed to carry on business in the gym. Staff are forbidden to sell drugs, etc. I know some of the lads use gear. That is their business. We have had guys sell gear in the parking lot years ago. Truth be told, bodybuilders don't tell me what they are doing re supplements. That is the way I like it. I haven't sold steroids or other drugs to anyone let alone gym members. We no longer sell supplements because one of my instructors set up a store a few years ago and the heads go there. I honestly can't sell supplements because I consider them unnecessary. I tell that to those who ask but the knuckleheads still go and buy protein, etc.
The video is right about one thing, gyms are high investment, low return businesses. Also they are time consuming because most are open from early in the morning until late at night.
There are gyms everywhere now. Windsor has 6 gyms and a population of about 26,000. All those gyms can't make a profit. Three are open 24/7.
