The equipment is incredibly sturdy, with great integrity. Really indestructible. More importantly, I'm able to maximize the simplest routines - pushups, squats, mountain climbers, etc. It has also allowed me to better my stability, especially after repeated injury to my ankles. Strengthening my ankles and lower extremity through simple techniques is significantly more effective when coupled with the Therrex board. I'm looking forward to learning new stabilizing techniques to strengthen my balance and motion.
