Abstract: A multi-functional leg stretching apparatus comprises an anchoring device made up of a positioning seat and a retaining block for the winding around of an elastic strap there-through, a fixed inner tube securely mounted at the anchoring device therein with both ends thereof symmetrically protruding outwards at both sides of the anchoring device, and a pair of movable outer tubes that, each having a pedal, and plate-like protective frame with an embedded support plate mounted thereto, are symmetrically joined to both ends of the fixed inner tube thereof. A resilient member is accommodated inside the fixed inner tube to extend outwards at both ends into which an abutting element is respectively adapted to abut against the adjacent outer edge of the movable outer tube thereby, permitting the abutting elements affected by the bounding force of the resilient member to flexibly draw and limit both movable outer tubes gathering towards the positioning seat of the anchoring device thereby.

Abstract: A multifunctional training machine, that includes: a frame; a device for bending the user's body upward from a lying position, a seat, mounted on the frame a back rest, hingedly mounted on the seat and being raisable and lowerable, a gliding frame, glidingly mounted on the frame in front of the seat and movable back and forth and having two foot rests, and a transmission mechanism, connected to the gliding frame and the back rest and transforming the longitudinal movement of the gliding frame into raising or lowering of the back rest; a hip support for stretching the hips of the user, mounted between the seat and the back rest, close to the back edge of the seat, the hip support being vertically movable, so as to raise the hips of the user above the seat; and a pull bar, connected to the foot rests, for pulling up the foot rests, while the user presses in a contrary effort the feet on the foot rests; wherein the user can perform the exercises of bending the body upward from a lying position, stretching the hi
