Product Description (from their site):
Develop grip like a Ninja. Don't let you fingers, grip, forearms, or biceps give out half way up the rope climb!
Thick bar training and adjustable hand grip strengthener in one.
Using a thicker diameter bar causes much greater muscle activation throughout the arms because it forces them to work much harder. This increased muscle activation leads to bigger, faster gains in muscle size and strength. Ninja Grip thick bar trainer measures 4.7 inches in length and 2.2 inches outer diameter for easier grip. The grips are made from a durable silicone material that won't compress under heavy loads.
The hand grip strengthener is easy to use and adjustable: Just twist the dial to adjust from 22-88 pounds of resistance. Adjust the resistance to match your ability and increase the resistance as you gain strength.
Grab a second set for your workout partner because ninjas don't train alone.
