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. Therefore, via the aforementioned structure thereof, the stretching apparatus can not only stretch both arms and legs of a user in a straight direction, but can also strengthen the exercise of legs in an alternative transverse direction so as to train muscles of different parts for bodybuilding thereof.
