The American College of Sports Medicine (ACSM) has released results of a survey predicting the worldwide top 10 fitness trends for 2014.

Leading the way is increasingly popular high intensity interval training (HIIT), which involves short bursts of activity followed by a short period of rest or recovery, usually conducted over a 30-minute period.

For the first time in the survey's history, body weight training has appeared in the results, coming in at number two in the list. The trend allows for the use of minimal equipment making it more affordable for fitness enthusiasts.

Another intriguing entry into the trends list was the application of age-appropriate methods. Entering into the results at number seven, the trend conveys the extra effort that fitness professionals are taking to create age-appropriate fitness programs to keep older adults healthy and active.

The list’s eighth entry is also closely related to age, with the idea of functional fitness looking to improve people’s balance while seeking to ease daily living.
