GMX7 X1-PRO 50M

The X1-PRO is the ultimate resistance device for swimmers, it comes with all accessories needed to connect it to a lane line as well as a belt and leash for a swimmer.

These devices are constantly pulling the athlete back, up, and/or down which puts unnecessary stress on the athlete?s joints. Zero to Immovable Resistance: Calibrated for easy adjustment with the twist of a tightening cap within seconds. Measurable and Duplicatable: The X1-PRO shuttle has 31 marked settings enabling identical precision with each and every X1-PRO. Resistance up to 50
