ok question about my weight loss...

I've now expanded my walk to 4 miles i believe it is and i still am doing it in just under an hour but when i get back i'm barely sweating and not out of breath...the dog on the other hand is dead lol...

will i still lose weight even though im not all gross when im done...

why the sudden change in my bodys reaction

well, I'm not an expert on this...but try it out for a while and see where it goes. if you see no change after a while, then increase the difficulty. it's healthy, regardless!
