Consumer Product Reports And Tests

Over the years, fitness product articles have consistently been the most popular studies.  In this article we tested a simple device, a pull-up bar.   The cost was $19.  After review, the device seems very cost effective if used properly.   Let's review: Isometric means a static contraction of the muscle where there is no lengthening or shortening of the musculature.  Flexing your bicep or performing a body plank hold are simple examples. Performing a pull-up or a chin up would be an example of concentric exercise when your body is moving upwards and an example of eccentric exercise when the body is slowly lowered.  Stopping your body with zero movement in any working position would be isometric exercise.
