 My prosthesis couldn't cope. The hydraulic cylinders in the prosthesis would explode. They couldn't withstand the forces that I was putting through them. As the leg was coming out straight, the piston would pull out of the hydraulic unit and hydraulic fluid would go all over the track and that would be my training session done. At this time, my prosthetist, and I was calling him up quite regularly saying, Tom, I'm really sorry, I've broken another cylinder. I blew another leg. Yeah, yeah, I blew it.
