The weight vest gives the added resistance needed to take your plyometric and Crossfit training to the next level. There is no better way to add resistance to your box jumps, pull-ups, dips, and running exercises. The weighted vest provides the proper bio-mechanics and weight distribution necessary for reducing the risk of injury during exercise. Your Crossfit and Plyo workouts will safely be taken to the next level when you train with a weight vest. This will result in an increase in speed, strength, vertical jump, and power.
