Emma Obayuvana:

“I think you should be doing about 20-30 minutes of HIIT a week, total. You can divide that up and perhaps do it over two sessions. Even then, it will depend on what your health state is, if you’ve been signed off to do it, if you have any heart conditions or any joint issues that would be exasperated by random bursts of HIIT.

A lot of people like the feeling of getting super sweaty and ‘beasting’ it in their workouts, so they turn to HIIT. But we shouldn’t be pushing our bodies to that extreme on a regular basis. Mix up your 30 minutes of HIIT with a few strength training sessions and maybe some steady state cardio, and you’re doing enough.”
