Designed to contour and stay tight to your body even during the most intense workouts, the MiR 20-pound adjustable weighted vest adds resistance to your training programs without compromising your biomechanics. The vest, which fits on both men and women, fits snugly to your body, allowing you to move and breathe easy when you work out. It’s also easy to adjust the weight by adding or removing individual weighted bags. Once fastened to your torso, the vest offers resistance for such activities as power walking, hill bouncing, running, lateral drills, and vertical jumps. As an alternative, you can use it in the gym when performing squats, lunges, dips, pull-ups, push-ups, and more. Adjustable in 3/4-pound increments, the weight vest helps you increase strength and speed, accelerate weight loss, improve respiration, build muscle, and gain quickness and power. The one-size-fits-all vest carries a lifetime warranty.
