Reply #12: Start slower [View All]

I had this discussion with my little brother who will be running cross country for the first time this fall. He hasn't been running yet and they have a mileage goal this summer. He plans on running 3 miles to the school, weight lifting for a while, and then running back everyday. Even if he (and you) have the will to start out exercising at the level of a conditioned person, he (and you) will get hurt and be unable to exercise.
I was a runner and had to run high mileage for college cross country. Guess what happened to people on the team who did not condition properly during the summer. It didn't matter that they had the drive to do the workouts. They didn't have the strength to take all that pounding.
What your doing isn't as stressful on your body as running but you still could get injured if you do too much too fast. If you haven't been in the habit of regular exercising, you should only do one session per day for a week and see how you feel. If you feel fine, add more. If you hurt and are fatigued, stay at that level for a while. Maybe in a few months you will be able to exercise like you described.
Physical conditioning cannot be rushed.
