An apparatus for dynamically exercising the leg and hip muscles employing squat maneuvers. Specifically, the apparatus includes a base on which the user stands and a back support that is mounted such that it maintains a vertical attitude while being moved by the user along a arcuate path as the user performs a squat movement with his back in contact with the back support. The controlled movement of the back support is accomplished by first and second parallelogram-type side assemblies so mounted with respect to the base at one of their respective ends and having the back supported therebetween adjacent their outboard ends, that such side assemblies provide pantographic type motion to the back support. Shoulder blocks associated with the back support are adjustable to accommodate users of various physical heights.

Apparatus for exercising the muscles of the legs and hips of a user comprising: a substantially horizontal base means; first and second side members, each such side member defining a parallelogram, including first, second, third and fourth leg means, said first leg being fixedly secured uprightly with respect to said base means, said second and third leg means having one of their respective ends pivotally connected to said first leg means at spaced apart locations along the length of said first leg means and extending therefrom in substantially parallel relationship to one another, said fourth leg means being pivotally connected to the outboard ends of said second and third leg means at spaced apart locations along the length of said fourth leg means whereby when said second and third leg means are pivoted about their respective points of connection with said first leg, said fourth leg means moves along an arcuate path but is maintained substantially parallel to said first leg means; said first and second side members being spaced apart from one another; back support means mounted between said first and second side members and movable therewith; shoulder contact means associated with said back support means and adapted to receive the shoulders of a user of the apparatus when the back of such user is in contact with said back support means for exerting a lifting force to said back support means.
