If You’re Constantly on the Go: High-intensity Interval Training (HIIT)
What it is: Bursts of intense exercise like sprinting or jumping jacks, done for about 20 to 60 seconds, followed by short intervals of easy exercise like slow walking. HIIT is No. 1 on this year’s trends survey from the American College of Sports Medicine, which polled thousands of fitness experts worldwide, including Canadians. Why? This challenging workout usually only lasts 20 to 30 minutes, making it ideal for people who don’t have tons of time. The quick interval changes also banish boredom. And it’s great for burning calories-as many as 15 a minute, according to one recent study from the American Council on Exercise.
