I remember the days when I did weights, and cardio, and all that. Then, the knees started going.
If you don't adjust your eating habits, the weight piles on.
If you don't keep up with the workouts, the flab starts. I think it starts anyway.
I'm down from about 245 to about 223 as of this morning, and going for more.
I figure it's gotta help the knees, heart, lungs, etc... w/o all that extra weight to lug around.
When younger, I thought it important to get bigger, now I'm gong the other direction. Wish I was this smart when I was 25.
