Thanks for the advice everyone. Believe it or not, but I'm REALLY taking all your suggestions very seriously---as I'm still a newbee.
I will need to buy a heart rate monitor----but whats confusing about cardio, is that some say low intensity is better because you burn fat right then and there, but others say high intensity is better because it raises your overall metabolism. I have been doing high intensity, and I LOVE IT. I get such a high from it. And once in a while I will do a long cardio session and just keep my heart rate stable. But I seem to get way better results with the high intensity, plus my workout is 1/4 the time.
Also---I kind of have a little secret goal besides losing fat, and gaining muslce, lol-----I want to be super girl!!
I kick ASS on the treadmil. I have never seen anyone at my gym do what I do---not trying to sound stuck up, but I'm actually proud of how fast I can run.
This was my old high intensity workout, I have just made one even harder:
warm up walking for 2 mins at 4.0 MPH
Then raise the speed to 4.6-5.5 for 1 min
Then raise the speed to 7 for 1 min
again raise the speed to 8 for 1 min
Then raise the speed to 9-9.5 for 1 min
Take it back down to 4 MPR for 1 min
You do that 3 times, then on the last round right after running for 1 minute at 9 MPH--raise the speed to 10 MPH AND put the incline on 10 as well--and run for 1 minute, then walk for 2, and your done.
That has actually become too easy for me now---so I've made another one.
So basically, I can handle hard sprinting--did you know the treadmil only goes to 10 MPH? I never knew that.
