And Zuke2, here is the thing, as a 10 year-old you really don't need more. Push-ups and some of the other exercises (and progressions) in this article will serve you well at this stage in your development. Once you build a solid base (again, using the exercises from this article), and it takes time to do so, it will THEN be time to add to your strength training routine (deadlifts, maybe some olympic lifts, squats with added weight, bench presses etc).
Maybe I'll write another article here in the near future for those that are mastering the exercises outlined in this article, and ready "for the next step." But again, at age 10 don't worry about "the next step" yet.
