Tree Climbing Practice is a training method used to gain more skills with chakra control. This training involves focusing a fixed amount of chakra to the bottom of one's feet, and using that to climb a tree without using one's hands. If the stream of chakra is too weak, the user will lose their footing on the tree and fall off. If it is too strong, the user will be pushed away from the tree, causing the tree to break around the point of contact and the user will fall.
