Start slowly - Back to Basics.

Have you done your 30 min walk today? Research has shown that even a simple 30 minute walk each and every day can make your health and life a whole lot better. While walking is the studied mode, I’d be willing to bet that even a stroll in your wheelchair at a brisk walk intensity would have similar health benefits. So there aren’t any more excuses.

If you can’t manage to find a continuous 30 minutes in each day or on some days, then I know you could find three 10 minute ‘grabs’ in which to walk and get that body moving as it was designed to do: 10 minute walk to the bus stop in the morning on your way to work; a 10 minute walk at lunch time, and a 10 minute walk back from the bust stop in the evening is all it takes...and the benefits are almost as good. Unfortunately the benefits don't seem to be significant if you make your 30 minutes up of 5 minute portions, but I say anything is better than nothing.

Just move. Simply move. :)
