In this first video, Mike describes a sliding-x, followed by the basics of pre-equalization.
The following video takes what Mike just described to the next step. In this video he demonstrates a pre-equalized anchor off three pieces.
The stuff in the preceding video is quite rudimentary when it comes to anchor building and most advanced climbers have this skill dialed. It's important to practice a variety of anchors with legs that are a variety of different lengths. It's also important to practice building anchors with many pieces as well with only a few.
Speaking of building an anchor with only a small number of pieces, more advanced climbers that already have a strong understanding of their anchoring skills may find this next video a bit more valuable.
In this video, the guide provides a quick tip for keeping the power point high.
Practice makes perfect in every one of these techniques. So keep on practicing!
