I just think it comes down to finding something that you like doing and will keep doing, there is no point starting something that you will never keep up, so if you love the gym or taking certain classes do that for me walking is fantastic for weight loss and improving my fitness level. The sad thing is so many people dismiss walking thinking its not intense enough when in fact it depends on the person doing it, the more weight you are carrying the more effort you have to put in to carry your body weight around plus if you push yourself more and more its amazing how much more ground you can cover, the different terrain you can cope with and how much quicker you can do it as time goes on. I always do two walks a day but lately have been doing three, often over rugged moorland and its working wonders for me, I tend to walk fast and the fact I do it every day at least twice a day often three times a day means the changes I am seeing are happening pretty quickly. I am also making my collie dog very happy indeed as the exercise really benefits her as well plus its free which has to be a good thing! I just love the fact that I can exercise and at the same time enjoy being out on the beautiful moorland, I have never understood why anyone would choose to use a machine that simulates the activity rather than doing the activity for real outdoors, for me I am out in all weathers and love it, I'm a true country bumpkin at heart!
