ABSTRACT:
A portable device adapted to be secured to a generally horizontal board, vis a bench in a locker room or the like, operable to assist an exerciser in doing situps and related exercises. The device has a single flexible board strap and a pair of flexible leg straps secured to the board strap. The board strap is of sufficient length to be wrapped around the board, extending transverse to the length thereof; and means are provided to secure the ends of the board strap together to hold the board strap firmly wrapped in place relative to the board. Each leg strap is formed of two pieces having adjacent end portions that are disposed on opposite faces of the board strap, and that are overlapped and secured together as by stitches adjacent the opposite side edges of the board strap. This secures each leg strap relative to the board strap at an orientation extended transverse to the board strap, and laterally holds the leg strap relative to the board strap, while allows each leg strap to be shifted axially along the length of the board strap into alignment on the upper side of the board with a respective leg of the exerciser. The leg straps are of sufficient length, after being twisted one-quarter of a turn, to be wrapped over an ankle or foot of the leg of the exerciser and overlapped, and means are provided to secure the overlapped ends of the leg straps together, operable to hold the foot or ankle firmly in place relative to the board.
