A symmetrical exercise bar is produced having a high radius of gyration for a given total weight with the center of percussion in the distal hand-grip when the exercise bar is rotated like a golf club using a two hand grip. The exercise bar has a light weight high flexure strength middle section for optimum resistance in upper torso exercises of the arms, shoulders, neck, back and waist. The exercise bar has two weights attached to the middle section covered by hand-grips adapted for holding with two hands and adapted for use over the shoulders and neck.

[ What is claimed is:] [1.]1. A swing-exercise device comprising:a light-weight flexible shaft section having a high flexural modulus;two-handed handgrips attached to each end of the shaft, the long axis of the handgrips being in-line with the longitudinal axis of the shaft whereby the device may be gripped at either end and swung as a golf club, the hand-grips being tapered with the smaller diameter end nearer the middle of the apparatus; andweights within each handgrip such that at least 60% of the weight of the device is concentrated in the handgrips with each weight within the handgrips being substantially equal;the device having an overall length of 35-50 inches and being symmetrical in proportion about its longitudinal axis and being symmetrical and balanced about an axis perpendicular to the longitudinal axis.
