To HIIT it big, crank up the tunes

Scratch most "regular exercisers" and underneath you'll find someone who tried HIIT (high-intensity interval training) once and just couldn't hack it-the short-but-extreme bursts of effort can be daunting for fitness pros and sweating like-a-pig newbies alike.

It's a shame, because HIIT can boost your body's fat-burning abilities and give you a time-efficient cardio and health strategy: Just 10 minutes, three times a week, can get you as healthy as the recommended 150 minutes a week of low-intensity exercise (see below). But there's hope: Listening to music of any kind- as long as it's your favourite tunes-during HIIT will make you not only enjoy it more but also look forward more to the next brutal session, says new research in the Journal of Sports Sciences. So pop in the earbuds and pump up the jams-the sweat will be even sweeter.

F*&#!! angry exercise can kill you!

Working out while experiencing anger can triple your risk of having a heart attack within an hour afterwards, says a Canadian University study that analysed data on 13 000 people in 52 countries.
