An exercise vest for upper body development is disclosed. The vest has a series of horizontal straps, adjustable in length, that encircle the vest and fasten in front to secure the vest on the person and provide upper body support. There are three elastic band assemblies to provide a complete range of upper body movements which involve all upper body muscle groups. Body development is achieved using the resistance of the elastic bands. A rear band is grasped by a handlebar and raised straight over the head. When not in use the handlebar is fixedly held above the shoulders by means of clips attached on each side of the vest. There are upper and lower side elastic band pairs which have hand grips for each hand. These elastic bands can be stretched up and down and forward and back as desired for a complete workout. The elastic bands are linearly adjustable by means of specially designed canisters containing winding spools that enable the lengths of the elastic bands to be altered in discrete increments. Each alteration of the length of an elastic band alters its resistance. The canisters also serve as the means to affix the bands to the vest.

By combining this natural stride action with adjustable resistance elements in the device, a wide range of uses, from strength training to rehabilitation, are achieved. The device generally includes footplates that are movable in forward and backward directions and also can be simultaneously moved upward against resistance. The heel of the foot can simultaneously be raised with respect to the toe of the foot, also against resistance.
