Using gravity and body weight, the Inversion Cuffs are an amazing conditioning tool best utilized by intermediate to advanced athletes. Try hooking them to a lower stall bar for a sit up station, or use a higher bar and incline for more challenging progressions. For the “all out” super-star athlete, hang fully suspended for a full body, power workout.

Sliders are a slippery oval disk that are used on carpeted floor and allow an athlete to move their body in a stationary space, or across the floor to work muscles. Whether working alone or in partners, these innovative exercises will help build strength, improve body shaping and increase flexibility.

  • 9" long; Color: Royal Blue/Charcoal
  • Slippery plastic on bottom
  • .5in foam on top

All materials meet CPSIA standards. Made in China. Designed in the USA.
