Detailed Description All Exerstrider poles are sold as pairs when you order. In just a few seconds you can begin to feel for yourself just how Exerstriding works! Just take your hands off of your keyboard and mouse and extend them out over the surface of your desk as if offering them both for a friendly handshake. Now make two fists and place them on the surface of your desk with your thumbs up. Finally, sit upright and alternately press one fist then the other into the desk repeatedly. Feel how your abdominal muscles as well as large back, arm, shoulder, chest and important core strength muscles contract each time you push! You'll do 1,800 - 2,000 similar muscle contractions per mile as you apply force to the Exerstrider poles with each stride! Because the work is shared by so many major muscles, you'll actually feel like you're working less while accomplishing much more...with even less risk of injury. Let me show you how to work smarter, not harder, have more fun, and condition every major muscle as you walk! Exerstriding works all major muscles. Ordinary walking works only the muscles in blue letters. More than 50% of the body's total muscle mass is in the upper body, and with my easy-to-learn techniques you'll put all these muscles to good use with every step you take. Imagine how much more fitness you can build by simultaneously exercising all the body's major muscles! Fitness experts now stress the importance of upper body muscle conditioning in addition to aerobic fitness. You won't have to find time to do separate weight training workouts. Now there is a simple and effective way to enhance the aerobic effects of walking and build upper body muscle strength and endurance at the same time. Transform ordinary walking into total body Exerstriding! Only EXERSTRIDER® fitness walking poles come with both an instructional video and a printed, illustrated manual. (And walking.about.com has given the Exerstrider manual and video a 5-star rating!!) No matter how a person uses walking poles they'll likely realize some benefit, but in order to maximize both the results and safety of the activity you'll need to learn my easy-to-learn, highly effective techniques.
