I love to go on long hikes. That way it feels like there is a point to exercise rather then just burning calories. I want to get to the top of the mountain.

dpends what you mean by seeing results. On average you will loose between 1-2lb a week so depending on how much you have to loose will depend how long it takes. It doesn't matter what or who's exercise system you use you need to get the nutrition side of things right , it's 80% food 20% exercise no...

I try best to avoid it when I can. I'll always take half the bread off sandwiches and order any hamburgers I get protein style (wrapped in lettuce).
