Hi, I have a son and he practices athletic.He representing his country (colombia) and he is national champion of pol vaulting and the second places in South America. But the most imprtant is the coach: Here in Bogota, we have a good coaches, but we dont have good tools (good poles vault). My son does many exercises every afternoon. He always go to the training center for practice Jumps, force in his arms, run, what ever he needs practice every time more!.
