  • Patent number: 6248048
    Abstract: A portable folding exercise apparatus has left and right side frames pivotably attached to a cross brace. Handgrips on the side frames are useful for performing traditional dips and knee raises, with the apparatus in an upright position. A cross brace has a pair of parallel handgrips useful for performing close parallel regular push-ups, tricep dips, abdominal crunches, arm curls, hammer curls, and shoulder presses. The exercise apparatus is preferably formed of welded steel tubing, and is sufficiently rigid to resist excessive bending or deflection during use, even under extreme loads generated by heavy users. Quick release pins lock the side frames into an open position for use and may lock the side frames into a closed position for transport or storage.
