The Rolling Thunder--a universal test of grip strength that started a sport and setted a standard.
One of the world's premier tests of grip strength, the Rolling Thunder is a training tool of first choice for everyone from armwrestlers to rock climbers and will become one of your favorites as well. Hook it up to a loading pin and clip (not included) or bind weights with sting or chain, for one-hand deadlifts, doing either reps or holds.
The thick-handled one-hand deadlift is a 20th century archetypal test of grip strength and the Rolling Thunder Deadlift is now a 21st century grip competition staple worldwide.
