Fitness trends come and go every year, but we’re going back to the basics in 2018, according to a new annual survey from the American College of Sports Medicine (ACSM) published in its Health & Fitness Journal.

For the survey, the authors identified 40 possible fitness trends for 2018 and asked more than 4,000 fitness pros from organizations like the American Council on Exercise and the National Council on Strength and Fitness to rank them on a 10-point scale, with 10 meaning it was most likely to be a trend this year.

The ACSM also distinguished the difference between a trend and fad in the survey. A trend was defined as having more lasting power than a fad, which is typically met with more enthusiasm but lasts for a shorter amount of time.
