Arm Exercise Spring Chest Expander Transformer 4,4m at wholesale

Of the existing ones, this is the only model with step-by-step adjustable length, as well as a change in the tensile force of the expander.
 

Transformer and its advantages:
- changing length and tensile force (maximum 4 times);
- suitable for working out both small muscle groups (biceps, triceps, trapezoid, deltoids), and large (latitudinal backs, pectoral, quadriceps);
- comfortable handles with a soft coating;
- reliability and simplicity of a self-locking lock mechanism for adjusting the length and tensile strength of the expander;
- the ability to independently change the length change step (by adding additional nodes on the expander bundles);
- the ability to simply fix the loop or handle of the expander in the doorway (bottom, top of the door or at any other height);
- compactness and light weight of the product (you can easily take it with you on trips); - the ability to conduct classes with a wide range of movements in large rooms and in cramped conditions, for example, in a train car, car, plane;
- when performing exercises with the help of two expanders, a significant increase in both the amplitude of motion and the effort of the exercises.
