I have been told that I may have muscle loss in my leg. I have been exercising with walking 3 miles a day about 5 times a week and water aerobics. I have lost 25 lbs since September. I stopped eating sugar and starches for the most part and my readings have been no higher than in the 90's. That is a change from 200 - 220 readings. What do I do to correct this if it is a problem?

Heart rate is the key. substract your age from 220. multiply that number by 0.65 and 0.85. The numbers will represent your heart rate for aerobic and anaerobic exercise. aerobic exercise will burn fat. anaerobic exercise will burn muscle tissue.

Aerobic exercise allows the respiratory system to provide adequate amounts of oxygen to tissues to allow the burning of fat. anaerobic exercise (vigorous exercise) does not provide enough oxygen to feed the tissues, so the body starts breaking down muscle tissue.

anaerobic exercise will increase the metabolism, so it should be a small part of every exercise program.

Or, you can increase your exercise level until you cannot carry on a conversation. That is the beginning point for anaerobic exercise heart rate. Be aware that the heart rate for both will change as you increase your exercise, because of increased lung capacity, and vascular increases due to exercise.
