There is a gym on every corner in Southern California. There’s also at least one K-Mart or Walmart in every city in Southern California. But, would you be willing to go to a K-Mart / Walmart level facility for your health care? Probably not, so why would you trust your fitness, health and overall well being to a K-Mart level gym? K-Mart and Walmart are great for quick shopping and items that can be replaced often. The things at K-Mart or Walmart are inexpensive so we don’t expect the highest of quality. However when you need a wedding gift for your best friend or your boss you’re probably going to go to a higher end store. You can still save money at a higher store, but you definitely want a quality item. Right?
