Soooo, I'm a runner. Surprise! Many people ask how is that I keep my shape and well quite frankly believe it or not it's ALOT of work. Running is one of the key exercises I do to keep in shape. You can do it too. (stay in shape that is) Just 30 mins of exercise a day will do it.
Do ANYTHING that gets your heart rate up for 30 mins a day. Run, walk, bike, swim, jump rope, dance around your house like crazy etc. No excuses! Get it done! You'll feel great when you're done too.
Me? I run.
