For uphill hiking, shorten poles 5 to 10 cm and plant them slightly behind your body; for downhill.
Most people grab trekking poles, set them once at the start of the trail, and never adjust them again. That works fine on flat ground, but the moment the grade changes, your elbows lose that 90-degree angle and the poles stop delivering leverage or shock absorption.
Getting the most out of your poles means changing their length for every major terrain shift — uphill, downhill, and traverses. This guide walks through the adjustment numbers, the planting technique, and the biomechanics behind both, so you can hike harder with less joint strain.
Adjust Pole Height To Match The Grade
The baseline for any pole length is simple: when the tip touches the ground in front of you, your forearm should be roughly level — think a 90-degree angle at the elbow. That neutral setting works best on flat or gently rolling trail.
For long uphill sections, shorten each pole by about 5 to 10 cm (2 to 4 inches). That brings your grip closer to the ground and gives you more leverage to push your body forward. REI’s expert-advice guide confirms this adjustment helps you plant the pole more securely as you climb.
For downhill descents, lengthen each pole by the same 5 to 10 cm. The extra reach helps you plant the pole in front of your body, where it can absorb impact before your knee has to. Most adjustable trekking poles use a telescoping or folding mechanism and are designed for people who are 5 to 6 feet tall, so check your specific model’s range.
Why Most Hikers Stick With One Length Too Long
It’s easy to forget about the twist-lock or flip-lock joint once you’re moving. But keeping poles at the neutral length on a steep climb means your arms are too high to push effectively, and on a steep descent your poles hit the ground too late to brake. The difference in technique is small but matters a lot.
- Uphill leverage: Shorter poles let you plant the tip slightly behind your body and push yourself forward — a motion that recruits your arms and shoulders to share the leg load.
- Downhill absorption: Longer poles let you plant the tip slightly in front of your body, so your arms take some of the shock before it travels to your knees and hips.
- Traverse stability: When crossing a slanted trail, shorten the pole on the downhill side and lengthen the one on the uphill side. That keeps your torso more upright and your center of gravity over your feet.
- Steep climbs: On extremely steep sections, some hikers place their hand on top of the pole handle for extra push. It’s an anecdotal technique from experienced hikers, not a formal recommendation, but worth trying if your grip feels awkward.
The common thread is that one length never fits every terrain. A few seconds of adjustment at the trailhead and the top of a ridge pays back in lower perceived effort and fewer sore muscles the next morning.
Uphill And Downhill Footwork That Fits The Poles
Pole length is only half the equation — where you plant them matters just as much. On flat ground, use a natural arm swing with the opposite pole to opposite leg, planting near your trailing foot to keep a steady rhythm. That same rhythm carries onto climbs and descents, but the planting point shifts.
Uphill: Plant Behind, Push Forward
As you step uphill, plant your pole slightly behind your current front foot, not ahead of it. That angle lets you push off the pole to drive yourself upward, engaging your triceps and core. If you plant in front, you’re just stabbing the ground without gaining propulsion.
Downhill: Plant In Front, Absorb Shock
When heading downhill, plant your pole slightly in front of your body. The tip should hit the ground just before your foot lands. That timing lets your arm and shoulder absorb some of the impact, which can reduce the compressive force on your knees by up to 25 percent, per REI. Many hikers also find that a loose posture — hips slightly back, weight off the poles — helps them stay balanced rather than relying on the poles as crutches.
On a traverse, you can adapt this by using a technique some hikers call “short one, long one” — adjust poles for traverse to keep your torso upright and your foot placement secure on the angled trail.
| Terrain | Adjustment | Planting Point |
|---|---|---|
| Flat ground | Neutral (90° elbow) | Near trailing foot, opposite arm |
| Uphill | Shorten 5–10 cm | Slightly behind front foot |
| Downhill | Lengthen 5–10 cm | Slightly in front of body |
| Traverse | Downhill side shorter, uphill side longer | Alternate as needed |
| Steep descent | Lengthen + optionally “brake” with both poles | Simultaneous in front |
The table above covers the major adjustments. On particularly steep downhill sections, some hikers use a “braking” technique by planting both poles simultaneously in front of them to slow their descent — useful for loose scree or wet rock where you want extra control.
Step-By-Step Technique For Every Gradient
Once you know what to do, a quick routine at each grade change helps you remember. Follow this order when the trail tilts.
- Check your elbow angle. With the pole tip on the ground directly in front of you, your forearm should be nearly horizontal. Adjust the length until it is. That’s your neutral baseline.
- Adjust for the coming grade. Before starting the climb or descent, shorten or lengthen both poles by 5 to 10 cm. Do it while standing still — fumbling with a twist-lock mid-step is awkward and dangerous.
- Plant behind for uphill. As you take a step uphill, push the pole into the ground slightly behind that same-side foot. Transfer weight into the pole as you straighten your arm.
- Plant in front for downhill. On the descent, let the pole tip hit the ground just ahead of your front foot. Keep a loose wrist and a slight bend in your elbow so the pole can flex and absorb.
- Swap lengths for traverses. If the trail is slanted, quickly shorten the downhill-side pole and lengthen the uphill-side pole by a few centimeters. Test the angle with one step before committing.
If you’re carrying a backpack, the extra weight makes good pole technique even more important — your knees will thank you less for the steep stuff if you skip these adjustments.
What Research Says About Joint Protection And Energy
Using trekking poles isn’t just about balance. Research summarized by REI and Outside Online shows a few clear benefits for your body. On downhill sections, poles can reduce the compressive force on your knees by roughly one-quarter by shifting some of the load to your upper body. That same research notes that poles also reduce muscle soreness in the legs after a long hike, particularly in the quadriceps.
On the energy side, using poles makes you burn about 20 percent more calories — not because it’s harder, but because you’re using more muscle groups. In return, many hikers can maintain a longer stride and a faster pace with the same perceived effort. REI recommends using two poles over a single hiking staff because it provides more balanced support and keeps your gait symmetrical.
One key tip from experienced hikers: when going downhill, keep a loose posture downhill — hips back, knees slightly bent, and poles used for balance rather than full weight support. Over-leaning onto your poles can actually destabilize you and reduce the knee-protection effect.
| Benefit | What The Research Suggests |
|---|---|
| Knee force reduction | Up to 25% on downhill sections (REI) |
| Energy expenditure | ~20% increase (Outside Online) |
| Muscle soreness | Reduced in legs post-hike (Outside Online) |
| Balance improvement | More stable on uneven terrain (REI) |
The Bottom Line
Adjusting your poles for uphill, downhill, and traverses takes about 10 seconds per switch but radically changes how your body handles a day on the trail. Shorten for climbs, lengthen for descents, and keep your planting point in the right zone — behind for power, in front for absorption. Those two habits alone can reduce knee strain and perceived effort significantly.
If you’re heading into steep, unfamiliar terrain, a gear retailer with knowledgeable staff or a certified guide can check your pole length and technique before you hit the rough sections — your specific height, pack weight, and the local trail conditions all factor into the perfect setup.
