Abstract

An exercising machine for body builders or other athletes which facilitates the practice of squats, lunges, and similar lower body exercises, and encourages proper form as well as safety. A rigid steel frame of generally cubical dimensions, which rests upon a flat surface such as a floor, comprises upper and lower pairs of rigid, spaced apart rails. Vertical stanchions forming corners of the frame interconnect the upper and lower pairs of rails. A carriage assembly slidably disposed within the frame includes a pair of rigid, spaced-apart tracking side members which extend vertically between the upper and lower frame rails. A roller system at the bottom of the tracked side members enable it to roll on the lower rails, and similar wheels are employed at the top of the side members to track along the upper rails. During movement of the carriage operative alignment is preserved by telescoped compensation means which synchronize the track side members to prevent a bind or other inappropriate misadjustment during stressed carriage travel. A weight bar system extending between carriage sides may be loaded as desired by the bodybuilder. A padded, yoke-like collar associated with the weight bar harnesses the exerciser to the machine. Guide rods associated with each side member establish a vertical path for defining upward and downward movement, and weight bar sleeves coaxially mated to the guide rods enable vertical movements. The weight bar is pivotally mounted to the sleeves to facilitate its rotation to accommodate different exerciser movement and positions.
