I'm trying to incorporate HIIT cardio into my training for the next 10 weeks for a cut I'm trying to do. HIIT is new to me so I've been looking on the web and what I gathered from that information was that I should essentially go at 60% pace for 2 minutes, then 100% pace for 1 minute on and off.
Now... I can sprint 12mph for one minute. If I'm doing my math right then that'd mean 60% is 7.2 mph. Problem is - after 2 minutes at 7.2 mph, one minute at 12 mph, and then 2 more minutes at 7.2 mph - there is NO WAY i'm going to be able to do another minute at 12 mph. Am I just really out of shape or am I doing the HIIT incorrectly? If so, what is the correct way. I'm skeptical that HIIT is really that much better than just jogging.
