Wellman’s job was not easy either.He got himself up the rope through upper body strength alone.In all，Wellman figured that he had done 5,000 pullups up the rope on the climb. However，when the two men first met，they never talked about climbing.“He knew that was how I got injured，” Wellman said.Until one day Wellman decided that he wanted to climb again and they started training. Their climb of Half Dome was not all smooth.At one point，pieces of rock gave way，and Corbett dropped down quickly.Wellman locked their rope in place，stopping the fall at 20 feet.His quick action probably saved his friend’s life. “Your partner can save your life—you can ，” Wellman said as the pair received congratulations from friends.“There are real close ties.”
