Handy and versatile, the fitness band from TheraBand is considered the smallest gym in the world. The rubber band made of 100% natural latex has been considered for many years in sports medicine, therapy, top as well as popular sports as THE training tool for strength and endurance training. The special feature of the TheraBand exercise band is the principle of progressive resistance: The further the band is stretched in length, the more force the exerciser has to apply. Unlike other exercise bands, this build-up of strength is almost linear due to the particularly high-quality material and excellent workmanship. The resistance that has to be overcome in the individual exercises therefore increases very evenly with the TheraBand exercise band and thus ensures optimal training conditions.
