A skating exercise system may include a resistance device, a roller skate that is not restrained by a track, and a cable connected between the skate and the resistance device. A skate may included a chassis, a plurality of caster wheel assemblies, and springs. The chassis extends along a first axis. The plurality of caster wheel assemblies are pivotably coupled to the chassis and located along the first axis. A spring is biased between each of the caster wheel assemblies and the chassis. In alternative, a skate may include a chassis and a set of rollers. The rollers are located along the first axis of the chassis. The rollers extend from a bottom of the chassis. Each of the rollers is able to rotate in any direction. |
