Maybe it’s because of the weather and how that encourages people to stay in shape, perhaps it’s the film industry, or maybe the water – but California is the top location for bodybuilding interest in the USA if you take it on the basis of how many gyms the state has.  As of 2019 – California had 30-40% more gyms (5123) than the second place state Florida (3285). In fact, California, Florida, Texas and NY all have entries appearing in this list of the best bodybuilding gyms in the US and it’s understandable why. They have more attempts at getting it right!
