What works when you are twnety doesn't work when you get older. As you get older it's different, and if you want to keep training your body, you can't work it as hard as you can every time out.
I'd rather do wind sprints everytime out too but my knees can't take it.
People who do over twenty minutes of cardio on a treadmill but pace themselves are working out smart sometimes, though I do agree that you don't have to be on there for an hour.
There are also cardiovascular benefits to prolonged exercise.
How old are you?
By the looks of your avatar, you can't be as old as I am.
Have you ever tried just walking really fast for an interval, then going slower, then repeating?
It looks silly, but when I first started training (I was a 280 lb tub of goo, so I couldn't do much either), it really jump started me (along with the horrific first few months of training).
I learned that it's more about how your excercise affects YOU more than it is about what other people are doing. If I get my heart rate up to 160 bpm by doing the stationary bike, I couldn't care less about that dude on the stairmaster.
Good Lord. Am I becoming a zealot?
