The TIYR Workout At FitnessSF Oakland

The TIYR Workout At FitnessSF Oakland. Inspired by Hope Solo and Robert Griffin III, i decided to try the TIYR Workout at FitnessSF Oakland. The TIYR is about 80 kg or over 200 pounds. That makes it a hell of a something to push around. Now I think the tire Hope uses is about 800 pounds. If that is the case, wow! Whatever the case it's a hard but addictive workout!
