HIIT top fitness trend worldwide

High-intensity interval training (HIIT)

HIIT was named the top fitness trend worldwide for 2018 based on an annual survey by The American College of Sports Medicine (ACSM). HIIT has ranked in the top 3 for five consecutive years, after previously being named to the top spot in 2014. HIIT did not make journalist Alex Hutchinson’s list of the hottest themes in fitness research for 2018. Instead, he identifies HIIT as a meaningful trend (and certainly no fad) — something that has caught on and will stick around for many years. Hutchinson’s five predictions for 2018 include compression of morbidity (and the concept of ‘healthspan’), individual variation, personal agency, case studies and play-based fitness.
