Climbing is a great way for kids to work on core muscle strength, balance, motor planning, coordination, visual focus and attention. Notice in the video how he has to attend to where to place his feet as well as where to move his hands to and what order to advance them. With a climbing structure such as the net he is using it is less stable so he has to engage his core muscles while maintaining his position and balance during the climb. And, the best part of climbing is its play!
