When I was a kid, my dad, being a Canadian, gave me a copy of the Royal Canadian Airforce Exercise Program. It was an ideal and quick way to get yourself in shape.

Take a few minutes to check out the exercise program. It is simple and quick and you can make time for getting a bit more exercise into your daily regimen…give it a try.
