Little did I know how popular this question was until I was in the process of googling it. Without even finishing the phrase “Do I need a pe” Google automatically gave me “Do I need a personal trainer?” and not “Do I need a pet?” as a drop-down option. Quite frankly, this made me realize that this question is on the mind of almost anyone deciding to make a change for their health. So I began looking deeper into the search results for this question and they were pretty underwhelming.
