  • What Is Isokinetic Training?

    Our exercise sessions typically involve isotonic and isometric muscle actions.  During an isotonic muscle action, the agonist (prime mover) contracts (or shortens) as the antagonist relaxes (or lengthens).  For example, when you bend your arm, the Biceps Brachii shortens and the Triceps Brachii lengthens.  During an isometric muscle action,  there is no visible change in muscle…

  • A Summer Challenge for Your Core!

    Here is a core challenge that can be performed anywhere, anytime, and all you need is YOU! The Plank is a very effective isometric exercise for strengthening your entire core musculature, including local and global stabilization systems.  Without  repetitively flexing and extending your back (common in many traditional abdominal exercises), the Plank places less stress on your…

  • Isometric Exercises Vs. Isotonic Exercises

    What is the difference between Isometric and Isotonic exercises?  Both are critical components of any exercise program, however isometric exercises are growing in importance.  Isometric Muscle Contraction:  The contractile force is equal to the resistive force, thereby producing no visible change in muscle length.  This type of muscle contraction is important because it dynamically stabilizes the body and…
