37yr. old mom, 5'3" and 126lbs, would like to lose about 6lbs. more. I love running but my knees hate it. (combo of poor genetics,and overenthusiasum in my younger yrs. ) Twice a week 3 miles on the treadmill at a 12mi/min pace is all i can handle without having problems. One of the trainers at my gym suggested I drop about 5 pounds to ease up the weight on my knees. I would like to try a sprint marathon. Do any of the elliptical machines equal a good run? Any ideas on increasing milage safely?
