ABSTRACT:
A physical training accessory comprises a garment or harness for securing the accessory to the body of a wearer, and a gatherable sail which is either permanently or detachably attached to the garment or harness. The sail, which may be comprised of any suitable gatherable material, is so fashioned that ground locomotion of the wearer, e.g., walking, running, skiing or skating, deploys the sail from a slack condition to a billowed condition, which increases air resistance which must be overcome by the wearer to continue the ground locomotion and so provides a valuable, extremely lightweight and compact training device. Fasteners may be provided to hold the sail in the slack condition for those times when the wearer does not wish to sustain the added air-resistance provided by the billowed sail.
