I just discovered a great tool for beginning Runners. It is called the gymboss. It is very inexpensive and is great for interval training. If you have never had running in your exercise program and want to begin to add it, the best way is with intervals. I am now running one minute walking two minutes and I am up to 6 miles. My goal is the Chicago Marathon in October. The Gymboss is great because you can set it at any interval you want and it will beep or vibrate. When I am jamming to my iphone music I can’t hear the beep, so the vibrate is perfect. Check out their website www.Gymboss.com
