HIIT workouts can be like hell on earth.
10 minutes in, you start to wonder if you might throw up and whether you’ll ever be able to lift your arms above your head again. And that’s just after the bloody warm up.
Will the pain ever end? Will you ever be allowed to stop burpee-ing and squatting and lifting?
Fortunately, the point of high-intensity training is that’s it’s hard but it only lasts a short period of time. And the fact that it’s shorter than your average workout means that it can be more intense.
Using as much energy as possible in a short space of time is a dead effective way of burning fat.
