发明名称 Swing exerciser
摘要 There is disclosed an exerciser sling which is formed as a generally U-shaped band of flexible sheet material having its upper ends attached to a support ring which has substantially the same diameter as the lateral dimensions of the user. The support ring protects the user's head, and supports the sides of the sling vertically and substantially parallel to each other, totally enclosing the sides of the user. The sling also includes a back support band which extends vertically from the support ring to a joined attachment with the fabric band of the sling at its lower rear edges, and has front belting which extends about the waist or diagonally across the chest and lower abdomen of the user. The sling has a pair of leg openings at its lower end, or bight, and the sides have opposite openings for the arms of the user.
