I have a workout plan that requires me to add 5 minutes to a fast paced walk on the treadmill every 2 weeks, by the last week i have to be at 45 minutes on a treadmill, now my problem is i simply dont have the patience to walk on a treadmill for 45 minutes on 4.0 speed. Hell, i couldnt handle to 25 minute walk last night...what are some alternatives to fast paced walking, i cant stay on a treadmill for 45 mins, i will be bored out of my mind, i listen to my ipod and watch the football games they have on, but i still cant stand being there that long, especially at a slow pace.
