Trenas Jaxpander

Trenas Jaxpander: the well-designed training device
The Trenas Jaxpander offers excellent training options for throwers of all ages and genders, both for javelin throwing technique as well as for specific and general athletics training. It is made of high-quality materials and is extremely robust. The shaft is made of stainless steel and equipped with a very robust cord binding. The widened tube opening on the javelin expander minimises friction on the expander ropes. The three bands are graded, resulting in a total of 7 different resistances. Further variations are possible thanks to the selected pretension (distance to the attachment point). The Trenas Jaxpander comes in a standard size and is suitable for javelin throwers of all ages.
