Tried my first HIIT workout just now got a great sweat in but I'm a bit worried that it's not as good for cutting as say a 10k or even a 5k! I just feel like I wasted energy and could have just ran 5 miles for cardio. Am I just doing a bad workout for my level endurance ( sprint 30 brisk uphill walk 30 seconds for 13 min) should I spend more time or find a way to up intensity?
