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. Features Smooth and Consistent Resistance: This helps to mitigate injuries while power training, as all other forms of resistance: baskets, towers, tubing, parachutes, etc., are more likely to cause injuries due to stroke alteration that occurs. 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 Meters: Any distance up to 50 meters of ?true? resistance from the moment the athlete pushes off the wall until they touch at the other end. Bi-Directional Resistance: This enables the athlete to train any set, any distance (if a coach can think it, now the athlete can train it, with resistance). Instant Stroke Correction: The moment the athlete makes an incorrect stroke and/or kick, for all four strokes, they instantly know how and when to correct it with the very next stroke and/or kick. Perfected Stroke Alignment: Provides perfect hip and body alignment for all four strokes with precision resistance on breakouts and turns. Lightweight and Portable: Weighs less than 4lbs, fits in any backpack, sets up in 2-3 minutes and can be dropped in any pool, anywhere in the world. Highlights Have you ever tried fitting a power tower in your back pocket? The X1-PRO is lightweight and compact enough that it fits easily in your backpack, so you can travel with it wherever your swimming takes you. We are tired of parachutes (limited adjustment options for resistance), heavy water belts (that travel nowhere), and stretch cords that sometimes break. That's why we decided to challenge the resistance industry and create the X1-PRO! The X1-PRO is an innovative aquatic resistance training device designed with swimmers of all levels in mind. Stepping into modern technology, the patented X1-PRO provides smooth, bidirectional resistance, allowing the swimmer to train with adjustable resistance through limitless workout options. Additionally, the device's constant resistance provides instant self-correction of technique, improving stroke efficiency. Try this revolutionary device yourself, and see the endless possibilities!
