Until today people used different kinds of elastic bands and tools, each one specific for a certain use or for one type of training.
No one had ever thought of how easy this kind of tool is to use:
- Open and attached to a fixed point from one end to the other;
- Attached in the middle in order to have both ends free to use as handle for every ring;
- Create an incredibly versatile additional ring by joining the 2 ends;
- 14 elastic rings covered in solid stranding layers in order to create a chain to train in a 1000 different ways, only with one tool.
