[1][2] Overhanging routes require a range of techniques to manage the demands placed on the upper body, as the feet are less weighted.
[3] Body positioning — keeping the hips close to the rock face and the arms straight — is important.
Advanced techniques such as the drop-knee, side-pulls-underclings-gastons, and the full range of heel and toe hooks are used for this.
Overhangs can force dynamic movements such as campusing and dynos, where the feet lose contact with the face.
[7] Gullich was a pioneer of plyometric training in climbing, which gave him the power to ascend severely overhanging routes.
