Center of Gravity and Balance in Climbing: Shift Your Weight First, When Three Points of Contact Applies, Hugging the Wall and Straight Arms

🌏 中文版

A few months into gym climbing, you have learned to watch your feet, but your arms still burn out halfway up. People around you say "three points of contact", "hips to the wall", "straight arms". You follow all three, and some moves get harder.

This post covers the one thing behind all three sayings: your center of gravity. By the end you will know where it is, why you shift it before you reach, and when to keep three points of contact and when to let go. It is part 2 of the Climbing Movement series, following Footwork. If you have never been to a climbing gym, start with the beginner's guide to climbing.

Where your center of gravity is: use your hips as the marker

The British Mountaineering Council (BMC) FUNdamentals coaching notes give a practical definition. Your upper and lower body weigh about the same, so your center of gravity sits a little below the middle of a line from your navel to your spine. You cannot see that point on the wall, so coaches use hip position as the marker.

The BMC calls moving your weight from one foot to the other one of climbing's most fundamental skills. It also names the classic novice habit: relying on the arms far too much. Your hands are in view and holding on feels safe, so you pull. Your legs have much bigger muscles; let them push.

The check on the wall is simple. Look down: are your hips directly above the foot you are about to stand up on? If not, part of your weight will hang from your hands as you stand.

Something you can do tonight: on a vertical traverse wall, do Climb Strong's Heavy Feet drill. The whole goal is to put as much weight into your feet and as little into your hands as possible. On every step, move your torso over the foot that is driving you, then see how close to the wall and how balanced you can get. Start with big holds and work down to smaller ones.

Shift your weight first, then move a hand or foot

In a 2007 column in the Taiwanese magazine Shanye Diaoyou, Huang Kuo-wei wrote this as "balance first, then move" (in Chinese). Before you move a hand or foot, shift your weight onto the other three points, settle, then move. His reason: without balance every move wastes energy, because you have to spend more effort stopping your body.

Lab measurements back up that order.

• How weight redistributes when a foot comes off: in Quaine and Martin's 1999 study, climbers on a vertical wall with four instrumented holds released their right foot. Afterwards the vertical load spread across the remaining three holds, while the horizontal forces sat on the left hand and left foot. In other words, when the right foot comes off, the limbs on the other side keep you balanced side to side.
• The body adjusts before it moves: Noé's 2006 study found that on a vertical wall, releasing a foot is preceded by anticipatory postural adjustments that shift weight in advance. On an overhang, with its larger base of support, those adjustments disappeared.

So "balance first" is not just a slogan; it is what your body already does. The common novice mistake is reaching before the weight has moved. The body wobbles, and the arms have to haul it back.

Something you can do tonight: do Climb Strong's Simple Triangle Drill. Traverse a vertical wall with plenty of holds:

1. Upright triangle: one hand on a hold directly above your head, feet a little wider than your hips.
2. Upside-down triangle: one foot directly below you, both hands wider than your shoulders.
3. Move back and forth between the two. Pay attention to the transition: the weight moves first, then the limbs.

"Three points of contact": where it came from and when to drop it

In the same column, Huang calls "three points still, one point moves" the climbing saying you hear most often. It has a history.

It used to be dogma

The German Wikipedia article on the Drei-Punkt-Regel (in German) lays out the history:

• The rule is to keep three limbs on the rock at all times and move only one hand or foot.
• The benefit is safety: if a hold breaks or a foot slips, you have a better chance of staying on, and loose holds are loaded less.
• Until the 1950s climbers followed it strictly. Otto Eidenschink's 1964 manual still presented it as a rule that must always be observed.
• Breaking it is often credited to the American climber John Gill. On his own site, Gill writes that in the 1950s anything beyond traditional three-point suspension was considered risky and heretical and was dismissed as a "lunge". He started practicing controlled dynamic moves as early as 1955.
• Then sport climbing arrived. Harder routes often lack holds for three limbs at once, and better protection made falling acceptable.

The article concludes that as an always-valid basic rule it is outdated. As a practice constraint in beginner teaching, and on poorly protected, loose alpine routes, it still has a place.

Good climbers are often on one or two points

Huang's observation is that strong climbers often have only two points, or even one, on the wall. So the saying really describes a state: balance, then move.

The next post gives a sharper example. To stop your body swinging open like a door, you often have to deliberately take your lower foot off, going from three points to two.

Keep it or drop it

Something you can do tonight: climb the same easy traverse twice. The first time, strictly keep three points and move one limb at a time. The second time, no restriction, but before every move ask yourself "has my weight moved over?" Compare which time your arms were less tired.

Should your hips be against the wall?

"Hips to the wall" is another common gym cue. Research says it depends on whether you are still or moving.

Holding a static stance, closer is cheaper. Quaine and colleagues (1997) had expert climbers release their right hand on a vertical wall in two positions: trunk far from the wall and trunk close to it. With the trunk close, contact forces on the holds were lower.

Climbing continuously, experts do not hug the wall. Zampagni and colleagues (2011) compared elite climbers with controls, and the result surprised them. The elite climbers kept their center of mass farther from the wall in both static and moving phases, by about 5 cm. Their center of mass also swayed more from side to side, with weight shifting back and forth between limbs.

Distance from the wall barely changes energy cost. Young and colleagues (2024) deliberately changed climbers' center-of-mass position and measured energy use with respirometry. The cost stayed the same. The authors conclude that climbing technique is mostly about stability and reducing fall risk, not saving metabolic energy.

Coaches make the same correction. Dan at Hooper's Beta says that pinned tight to the wall you get "blocked": the wall stops your rotation, and when a hand comes off you swing out. His fix is to find the plumb line, the balance point both side to side and in and out. People usually get the side-to-side part; the in-and-out part is what they miss most, staying too close even once they are balanced laterally. He frames this as a correction to the early "stay sucked in" teaching.

Huang's fourth principle says the same thing: be close to the wall and away from it. Get close to rest; move away a little when you need room to see and move.

Something you can do tonight: try Hooper's Beta's relaxation drill. Before each move, think about one thing only: relax the arm that is about to move. Let your body drift away from your lower hand until you find a balance point where you are not pulling, then reach. If your body keeps swinging out as you reach, you are probably too close to the wall.

What straight arms actually save

"Straight arms" is another old cue. REI's climbing technique guide puts it as "straight arms are happy arms": a straight arm lets your skeleton take the weight, while even a slight bend means your muscles are working. The BMC agrees that straight arms put the strain on the skeleton rather than the muscles and are especially useful for clipping and resting, but it also says straight arms are not possible in every situation.

The catch is that straight arms mostly save the muscles that bend your elbow, such as the biceps. They do not necessarily save your fingers.

Bonelli and colleagues (2026) compared two static positions:

• Standing tall: legs straight, arm bent.
• Sitting down: legs bent, arm straight.

Sitting down put more load on the hand and produced higher activation of the finger flexors and the brachioradialis (a forearm muscle that bends the elbow). On the overhang, standing tall used more biceps and latissimus dorsi. The authors suggest that climbers prefer the straight-arm sit on overhangs not because the fingers have it easier, but because of the overall pattern of fatigue and posture adjustment.

So use straight arms when resting, clipping, or when the handhold is good and there are enough footholds. On tiny holds with your fingers already fading, sitting down on a straight arm is not automatically easier.

Something you can do tonight: find a good rest and hold two positions for 10 seconds each. Once with legs straight and arm bent, once with legs bent and arm straight. Notice which one tires your elbow more and which one tires your fingers more.

When climbing square-on stops working

Everything above is "square-on" climbing: hips parallel to the wall, feet turned out. On slabs and vertical walls that is natural.

Once the wall tips past vertical, square-on starts to cost you. REI says hips squared to the wall push your weight away from it. British coach Neil Gresham writes in Climbing.com that climbing square-on on an overhang means pulling and locking off for every reach, and your body swings out.

The fix is to turn your hip into the wall, which is the subject of the next post.

Practice: four scenarios

Answers are under each question. Think first, then check.

1. On a vertical wall, your right hand is on a good hold and your left foot is on a high foothold. As you stand up to reach, your arms burn and your body tips backward.

2. A friend says, "Three points of contact, never break it." On an overhang, your right hand is on a sidepull and your right foot is on a hold. When your left hand lets go, your body swings open to the left.

3. You are on a good rest and want to shake out, but your body is glued to the wall and swings out as soon as you let go.

4. On an overhang with tiny holds, someone shouts "straight arms, sit down!" You do it, and your fingers give out faster.

Next steps

Once you can move your weight, the next question is what to do when the wall is steep and square-on stops working. The next post, Turning and Twisting, covers backsteps, drop knees, flags, and why barn-dooring happens. To go back and work on placing your feet, read Footwork.
