I am 48 years old and have been working at a new job for 2 months that has me walking(at a high pace) 8 hours a day. Over those 2 months, I have lost about 12 lbs of bw. When I look in the mirror, I look and feel small however, my lifts have actually gone up. I am not one to train for strength, but I don't like this feeling I have when I look in the mirror.
I am just wondering if its possible to lose muscle and gain strength. I am wondering if my problem isn't how I see/view myself and if I just lost unwanted bodyfat without training and my weight loss is purely excess fat. Thanks.
