If you prefer lying on a beach to sweating through Kayla Itsines’ bikini workout — or can’t imagine having the time to do either — this one’s for you. A recent 12-week study by researchers at McMaster University in Hamilton, Ontario suggests that in 60 seconds’ time you can reap the same cardiovascular and insulin sensitivity benefits as you would after 45 minutes of moderate exertion — the key is to grind like hell for that one minute. Call it the go-hard-then-go-home method, patent pending.
Experts have touted the benefits of high-intensity interval training (HIIT) for nearly half a century. HIIT consists of a short but extremely draining burst of exercise — essentially to the point of muscle failure — followed by a light exercise or rest period, followed by another grueling if brief phase, and so on and so forth until you’re either the Rock or vomiting on AstroTurf.

In a world where, essentially, no one feels they have enough hours to devote to the gym, HIIT methods have taken off. While the one-minute interval seems almost too good to be true, the scientists at McMaster University, veterans to the study of interval training, were sure to cover all (well, most) of their variable bases.
