finding HIIT really difficult!

kc101 Posts: 32 Joined: 2006/05/25	2008/03/09, 12:25 PM i've recently started HIIT, but i think somethings wrong with me. When i try to sprint at max. intensity i can't physically run as fast as i want to. like my legs just sorta give up on me. This happens before my heart rate gets as high as i want, and i feel no pain or muscle fatigue. My muscles just give up on me after a short while. I eat a high energy meal with carbs about 2 hours before i exercise, and i always feel like I've got plenty of energy, so i don't know how to explain it. So whats wrong?

I just want to know why i have to stop before my muscles actually hurt or my heart rate gets high enough...sometimes i barely sweat even though i feel i am really pushing myself.

If you are lacking oxygen, you will be extremely tired. -------------- Patience, persistence and perspiration make an unbeatable combination for success. Ivan Montreal Canada (City of Festivals)

I do this for 20 to 25 minutes and it is intense but doable. You need the rest between sprinting intervals to recover and bring your heart rate down some. You are still jogging and expending too much energy on the rest cycles. Try walking one minute and running 1 minute. It works.

When I started HIIT I sprinted for 30 seconds and then briskly walked/jogged for a minute and a half. Once that got too easy I did 30 seconds sprint/1 minute jog. I still don't do 1 minute/1 minute, but I go for at least 30 mins. Just do what feels right to you, and work up from there.
