sense i don't want my body to get used to going on the treadmill ninety minutes a day i'm going to change it up a bit, so for today, i'm going to go for forty minutes----at a speed of 8.8, instead of 7.7, so that way, i'll be burnining more calories in lesser amount of time. i haven't been able to stay on the treadmill during the whole forty---sixty-----or thirty minutes----that is the most i go on the treadmill at one time---and then i'll add another thirty, sixty, or forty, repetions, i used to do ten minutes repetions, but that takes too long, and i would rather go on longer, and then i just go on for one ten minute repetion, like i did yesterday. my body must have been really tired, cause i couldn't even get through the entire ten minutes without taking a break every once in a while. i also have to do some other workouts.
