Hi Pros, My son is 7 years old 1.31m tall with 31Kg. who has taken 2 years of basketball lesson, and 2 years of inline skating Hockey lesson. I am working on an interesting daily exercises plan. so that he can stick to, and become self-motivation. so far the arm strength is very weak which can't bear a 1chin-up work. So need your guys professional advice on how I am conduct the plan.
