The Finger Tester: Ninja Warrior Series

thingiverse

Designed to build finger strength and endurance, the Finger Tester is a useful training hold. When hung a pair, an athlete can grasp one hand around the underside of each hold and proceed to hang and rest for different intervals of time. If attempted daily, the Finger Tester is an effective means to quickly increase finger strength. Finger Testers are not usually included in course runs due to their difficulty, but they can always be held in the vertical orientation (with the pinkie resting on the funnel part).  To assemble this hold, a 3/8 x 3" eye-bolt is required, along with a 3/8" hex nut. The nut can be placed in the compartment on the bottom of the hold, and the bolt can be screwed into the hold until it makes contact with the nut. Make sure to twist it until secure! Following this, all you need is a spot to hang. I wish your fingers all the best! :)
