Just started walking an hour a day...over a mile straight up (843 ft elevation) and weighed myself for the first time in 2 weeks (5' 5" 138lbs before starting walking) and I gained 5 lbs. So frustrating .. this is not why I push myself up the freezing cold and rainy hill every day. Suggestions? I can't believe it.
Muscle outweights fat with regards to density, which is why many people become discouraged at first. A better measure of your progress would be a proper body composition test to determine what percentage of your body is fat and what is fat free mass (FFM). Chin up! J
