Intro to Underclings

Overview

Underclings are one of the more unintuitive grips in climbing — you’re pulling upward on a hold that points down. They demand trust in your feet, body tension, and a good sense of movement direction. This guide will help you understand how to recognize and effectively use underclings. We’ll cover:

What is an Undercling?

An undercling is a climbing hold that faces downward, usually below chest level, which is pulled on by applying upward force. Instead of pulling down like with most holds, your fingers curl underneath the hold, and you push against it by pulling up while pressing down with your feet. Underclings are all about opposition — your hands pull one way while your feet and body resist the motion.

Using Underclings Effectively

When approaching an undercling, the key is to lower your body to create tension between your feet and the hold. Think about "sitting" into the hold and pushing with your legs as much as pulling with your arms.

Most underclings are not usable in isolation — they work best when paired with good footwork and a plan to move into a stronger grip above.

Body Position and Technique

Lowering Your Center of Gravity – Keep your hips below your hands when using an undercling. This creates the tension needed to keep the hold usable and allows your feet to do most of the work.

Foot Pressure – Unlike crimps or sidepulls, underclings rely heavily on your legs. Push into footholds to drive your body upward. Smearing and edging can both be useful depending on wall angle.

Hand Position – Your fingers should wrap under the hold and pull up toward your chest. Keep your elbows low and bent — if your arms are fully extended, you’re probably not getting usable tension.

Movement Strategy – Use underclings as intermediate holds that support movement into a more secure position. Often, underclings are transitional — great for gaining elevation or stabilizing, but not long-term resting points.

Summary

Underclings force you to think differently about how you climb. They rely on technique, foot pressure, and balance — not just pulling strength. Mastering underclings can open up sequences that look impossible at first glance. Focus on dropping your hips, pressing with your legs, and moving smoothly through the hold to the next one.
