Ever seen people step on this unique looking thing at the gym and wonder what the heck they are doing? The tool is called a Calf Stretcher and if you learn to use it, chances are you'll learn to love it as well.

What: A Calf Stretcher is a device that isolates the calf muscles.
Area of Body it Works: Calf muscles, ankles, and Achilles tendons.
Why: Stretching not only increases muscle flexibility, strength and balance but it also helps to prevent future injuries — the problem is that calf muscles are difficult to isolate without the aid of a wall or similar structure to lean against. The Calf Stretcher helps to eliminate this problem and is great for those of us who extensively use our legs for activities such as running.
How: Put one foot on the calf stretcher and slowly rock your heel back as far as you can (but not so far that it hurts) so your toe is pointing up toward your face. Hold the stretch for 15-30 seconds. For added support, stand by a wall or something to support yourself while doing the stretches.
