Is 20 minutes of HIIT cardio enough?
Researchers have repeatedly shown that people can burn comparable amounts of calories in HIIT routines lasting, say, 20 minutes, compared to longer continuous exercise routines lasting, say, 50 minutes.
Is 15 minutes of HIIT cardio enough?
Yes, a 15-minute workout is all you need — if you focus and push. The beauty of high-intensity interval training (HIIT) is that you’re working your heart at close to max effort (85% to 95%), so you burn a ton of calories while building superior cardiovascular strength in almost no time at all.
Is HIIT cardio good for weight loss?
