An exercising apparatus for bar bell-type exercises for the development and strengthening of major portions of the body including arms and legs, in which the forces are provided by resisting springs with the same freedom that weights are used in connection with the bar bells themselves and which are used in connection with the bar bells themselves and which includes a horizontal work bar that can be vertically connected to springs at its opposite ends and the spring force resisted intermediate its ends while the user is positioned between vertical guides. Top, bottom and vertically adjustable intermediate spring arm supports are detachably carried on opposing channel supports. Parts are provided so that the arm supports can be easily adjusted or disassembled and the bar is carried in sliding bar guides adapted to be adjusted in and between space formed by opposed channel guides extending vertically and held upon the base by insertion at their lower ends into laterally-spaced sleeve supports. Knob projections are provided upon the vertical channel guides and upon the work bar are disposed sleeve disc assemblies adapted to be engage the knob projections of the vertical guides to support the bar when not being used and which can, by the user of the bar, be easily slid out of engagement with the knob projections when the bar is to be worked against the action of the springs.
