Many personal trainers and fitness enthusiasts recommend plyometric exercises to others in attempt to improve power production.   In many cases, this is a good recommendation due to the fact that, when executed correctly, plyometrics can assist in improving power in specific movements.  An important pre-requisite that is overlooked in many cases is the individual’s ability to engage in this activity safely and effectively.   A quick and efficient way to determine if you or your client is ready for plyometrics, specifically higher intensity activities like depth jumps is as follows:  (1) Have them perform a standing jump and reach (vertical jump test) and record maximum height achieved (2) Have them perform a depth jump off an 18 inch high platform and record maximum height achieved.  If the maximum height achieved for the depth jump is not equivalent to the maximal height achieved on the vertical jump test, either delay plyometric exercise and focus on increasing base strength of legs and core, or lower the height of the depth jump and compare again to determine if depth jump activities can be started from a lower height.
