Abstract
Compression-type springs (36) are interposed between the upper attachment means (16) of a gymnastic ring set (10,12,14,16) and the suspension means (18,20) therefor. The lower ends of the springs (18,20) are attached to the suspension means (18) and the upper ends of the springs (36) are attached to the attachment means (16) so that downward forces on the ring set (10,12,14,16) causes the springs (36) to compress. The springs (36) are precompressed so that they only displace for downward forces in excess of a threshold, such as thrice the gymnast's body weight. The spring precompression also limits the available spring displacement in a desirable manner.
