Isometrics

photo8You might wonder from time to time why we do isometric exercises.  First, what is an isometric exercise?  An isometric exercise is any where the joint angle does not move, and force is applied while the muscle doesn’t lengthen or shorten.  For example, a plank is a perfect example.  There is tension on muscle, but you’re not moving through any range of motion.  These types of exercises are beneficial for strengthen the stabilizer muscles.  They are also great for modifying an exercise someone might not be able to do.  If you can’t do a pull up, build up your ability to hang from the bar.  Hanging is an isometric exercise that strengthen muscles that assist in pull ups.  They also increase mental toughness.  We all have had that mental battle while holding plank.  Our brain tells us to drop but we know we can continue.  So, let’s practice!
