The Shallow Rejector, 10 Inch Impossiball

  • 1 inch shaft between eye of bolt and top of ball.
  • Seamless grip area.
  • 14 lbs
  • Made with pure polyurethane.

3 Inch Ninja Warrior Nunchucks 800

* Discontinued *
    3.25" x 8.5" Nunchucks:

  • Pinch Strength Grip Strength Trainer
  • 3.25" Diameter, 8.5" Height.
  • 100 Grit Sandstone Texture
  • Seamless.

  • These guys are plenty wide to work your pinch strength. They'll be better than the Cowbells for people with smaller hands.
  • We played around with these guys at the 8" length, but it seemed just a little too short for lots of people to match with both hands. That extra half inch made a big difference! We made them 8.5" long to allow a wide range of people to use them for both pinch strength training and Ninja Warrior style obstacles.
  • Eye bolts are 3/8" Drop-Forged with a
    SWL of 1200 lbs.
  • Made with pure polyurethane.
  • Designed by Steve Dison.
  • Released 2015/08/23.
Rocket Ninja Warrior Training Pinch
Pinch Training Ninja Rocket

  • While the Cowbell (pictured in orange above) works as a difficult component in suspended obstacles, it was designed for pull-ups and grip strength training. We decided to go ahead and design a new product specifically for use in challenging obstacles. We call it 'Rocket'.
  • The diameter of the most narrow point is about 3.25 inches.
  • The height of the grip area is 7.75 inches so there's plenty of room for both hands.
  • Like the Cowbell, the base is 5 inches in diameter.
  • 100 Grit Sandstone Texture
  • We've also added a rounded glossy slippery top so, No Cheating!
  • Seamless. Designed by Steve Dison.
  • Eye bolts are 3/8" drop forged with a safe working load of 1200lbs.
  • Made with pure polyurethane.
  • Released 2015/10/26.
