When I was losing my weight I had just had a baby and all I did was walk. I wasn't about to leave my baby and hit the gym, lol. So, in the sling he went and we went walking everywhere, we both loved it. It worked for me.
I've starting walking my dog at a brisk pace for 30-45 minutes. Is this enough to help me? I don't have time for going to the gym, nor money to join one. Running is out of the question. I think my knees would explode. Cycling is not out of the question, but I think my wife would worry herself to death with me sharing the road with cars. I basically need something quick and easy to keep up, that's free. Walking the dog seemed to fit the bill. It's good for me and Lucy (the dog). I just don't know if it is going to help me or not.
