Tanner is 290lbs or 131kg and he climbs. We wanted to know what forces he gets when he falls on his gear so I sent him 3 LineScale3s and showed him how to film an episode. This was an amazing experiment of a test being done for HowNOT2 without me there. Tanner worked so hard to make this happen and Gritstone Climbing Gym was gracious enough to not only let him do this but Chris and Matt, the owner and manager, helped film and fall for science.
