Abstract
An adjustable weight-loaded dip-chin machine. Dip bars and chin bars with means for vertical adjustment are mounted on columns, which in turn are mounted on a base. An arm is pivotally attached to the base, and weights can be added to an arm spindle attached to the arm. A belt is attached to the arm, and the weighted arm spindle resist upward exerciser motion when performing dips or chins. A pivot hook releasably engages the arm spindle in an elevated position for convenience and safety when commencing and ending a squat exercise series. Means are disclosed for adjusting the height of the pivot hook on a column, and for automatically disengaging the pivot hook from the arm spindle when exercise commences. A squat platform is sized to fit between foot platforms, which together form a stable standing area for the exerciser. Squat handles are height-adjustably mounted to the columns.
