A lightweight frame for individual use, to promote safe locomotion, has a frame with two elongated, laterally spaced handles of adjustable height, for gripping by the user, and an arched support frame, providing unobstructed access between the handles, with a clear space for the user to safely prostrate themselves within the readily movable frame. The two frame lower portions extend laterally outward for enhanced lateral stability of the frame against tipping, and can serve as runners on ice, or be fitted with wheels or castors. The frame lower portions may be longer than the handles for greater stability. The frame is disassemblable, to facilitate packaging and transportation, and may have opposed matching portions of different length, to facilitate nesting together when packaged. Metal tubing, including sleeve couplings with set screws, may be used.
