A versatile baton (2) to perform a variety of muscle-developing exercises. A tubular elastomeric band (8) with an elastomeric plug (15) inserted within its opposite ends, expanding their tubular cross-section, is translated into an elastomeric insert (16) which bears against the inside wall of the tubular exercise baton. The combination of elastomeric plug and insert materials bearing against the elastomeric band avoids sharp edges, stress concentrations and the need for specially formed mating surfaces in the baton, and allows speedy assembly. The exercise baton can be a set of bar sections (4, 5, 6), capable of several assemblies, allowing uses of the equipment for different exercises. |
