I am a 53 year old female, 5 ft 4 in. and weigh 146 pounds. Last year at this time I was 138 pounds, but I strained the ACL in my knee and had painful feet which restricted my walking, so the inactivity of the last six months caused my weight to go up to 151. I am presently in rehab so my knee has improved and two weeks ago I joined the gym. I am doing the stationery bike, treadmill, leg extensions for the strain, and hip abduction to improve ostepenia condition in my hip, which is the reason my weight has fallen to 146 so far.

My doctor told me that slow exercise will burn fat instead of glycogen. What exactly is a slow speed on the treadmill in miles per hour and exercise bike in r.p.m.'s to burn fat, and how long should I stay on the equipment for fat loss?
Will a slow speed burn fat even if I don't hit my target heart rate?

I have muscolo-skeletal problems so I am restricted from doing upper body work right now, and I have sciatica so I cannot do any step machines. I have limitations on gym equipement use, so I am asking for advice regarding the bike and treadmill only. I really don't need a weight problem to make my physical condition worse than it already is.

I am trying the best I can with diet and the exercise I am permitted to do,
and my lower back and nerve pain feel much better since I have been going to PT and the gym. The nerve pain in my feet was so bad before I had treatment that I could not put my foot dowm without feeling terrible electric shock-like pain which kept me off my feet, but that has subsided, so I am optimistic about my physical condition improving and losing weight now.

Thanlks so much.
