On Friday, August 17th, the Bay Area Grip Challenge will be heading to Diablo Rock Gym for another round of tests of grip strength. One of the most active members in the Touchstone grip strength community, Daniel Reinard is known for his vast hand strength. He recently put together a video about one of the most common feats of strength- ripping a phone book apart. There are two methods used to pull so many pages apart at once, popping and grip and rip. In this video, he shows you how to do both. Check it out and get pysched for the upcoming event.
