Every year, people look for the newest trends in fitness. There have been some crazy trends over the past 50 years, such as the Drinking Man’s Diet of the mid-60’s and Air Shorts of the 1970’s. While most trends have very little science-y stuff behind them, there are some that we should take pretty seriously. If you are a fitness professional and your job is to help people become healthy, you should pay attention to these trends. Chances are your clients are reading magazines and are staying on top of things. You should be, too.
