View Full Version : Another HIIT Question.
02-16-2006, 08:22 PM
Ok I have done some searching and reading on HIIT. I am pretty clear on what it is....and that it is effective. What I cant seem to find the answer to is, when should a person consider starting HIIT vs. other options for Cardio. For example, in my situation... I am 5'9" and 255lbs...trying to get back down to 200. I started cleaning up my diet, doing WBB1 and cardio about 5 weeks ago. For cardio I have been doing an eliptical machine on an interval setting for 25 minutes....according to the machine my HR is usually around 175-180. At the end it says I have burned anywhere from 350-370cals (not sure how accurate this is). Oh, about 4 times a week. Anyway, should I stick with this program or do you all think I should switch it up? I guess I am also not clear on what 'high intensity" is... I know my big @ss is working during eliptical, BUT its not like I am sprinting for a minute. Thanks all....
If you are trying to burn fat AND muscle, 180 bpm is good. If you are looking just to lose the fat try to maintain 130 bpm and atleast 30 minutes. I say 30 minutes minimum because a lot of research suggests that the first 20 minutes only burn that days calories and not stored ones.
Sorry, I know this doesn't address HIIT just figured I would tell you what I know.

sheparay: true HIIT is difficult to do on a machine. Try sprinting for 10-20 seconds and then relax for 10-30 seconds and you quickly realize you'll be spending more time messing with the buttons than actually training. The best machine I've found for HIIT is a bike. But even some of those suck as a sprint sometimes causes the resistance to decrease. You'll have to play around with the machines or go outside.
ironman: The "fat burning zone" myth is less effective than HIIT at burning fat. Period. If you have a study to show otherwise, feel free to post it.
Anthony, I know, after seeing this post I went and researched HIIT. You are correct. I was just telling him what I know about fat burning - and yes, HIIT seems like a better approach. The cardio with low bpm is just an alternative.
