Combination free and stack-weight fitness apparatus
A combined free and stack-weight fitness apparatus utilizes a combination of free-weights and stack-weight assemblies to provide multi-mode fitness training. The total training resistance is a combination of free-weights attached to a barbell and stack-weight resistance transmitted to the barbell by cables. A pair of overhead cables attached to the barbell provide vertical support until a substantial portion of the weight on the barbell is borne by the operator.
