The #1 Mistake Carbondale Hikers Make With Their Knees

If your knees hurt more going down than up… this is probably why.

It’s a pattern we see constantly.

You start your hike feeling strong. The uphill is challenging, but in a good way; your legs are working, your breathing picks up, and everything feels like it’s doing what it should.

Then you turn around.

On the way down, something shifts. Your knees start to ache. You feel less stable. You might catch yourself leaning backward or bracing with every step. By the time you reach the bottom, your joints feel more beat up than your muscles.

The Real Issue: You’re Trying to Avoid Load Instead of Control It

The most common mistake hikers make, especially on descents, is trying to offload their legs instead of using them.

Without realizing it, many people lean back, stiffen their knees, and take heavier, more abrupt steps. It feels safer in the moment, but it actually does the opposite of what you want.

When you move this way, you bypass the muscles that are designed to absorb force (your quads, glutes, and calves) and shift that load directly into the knee joint itself. The front of the knee, in particular, takes on repetitive stress with every step down.

So instead of your muscles doing the work, your joints are left to handle it.

Why Downhill Hiking Is So Demanding

Descending a trail isn’t just the opposite of going up; it’s a completely different physical demand.

Going downhill requires what’s called eccentric strength, which means your muscles are lengthening under tension to control your movement. Your quadriceps are actively working to slow your body as your knee bends. Your glutes help stabilize your hips so your knee tracks properly. Even your calves contribute to controlling how your foot meets the ground.

If that system isn’t working well, or if you’re not allowing it to work, force has nowhere to go except into passive structures like cartilage and joints.

That’s why downhill hiking often causes more knee pain than the climb up. It’s not about strength in the traditional sense; it’s about control.

What Efficient Downhill Movement Actually Looks Like

Hiking downhill well doesn’t mean moving slowly or cautiously, it means moving with control.

Instead of leaning backward, your body should stay slightly forward over your feet. This keeps your center of mass where your muscles can actually support you. Your knees should stay soft, not locked, allowing them to bend and absorb force naturally.

Your steps should be shorter and more deliberate. Long strides tend to create a braking effect, which increases impact through the knee. Shorter steps, on the other hand, allow you to stay more balanced and responsive to the terrain.

Most importantly, your muscles should feel like they’re doing the work. A good descent often feels more like a controlled lowering exercise than a passive walk downhill.

The Missing Piece: Training for the Way You Move

Here’s where many active people get caught off guard.

They’re doing the “right” things: squats, lunges, general strength work; but they’re still struggling on hikes. The issue isn’t effort; it’s specificity.

Most traditional strength exercises focus on lifting or pushing, but hiking downhill is all about lowering under control. If you’re not training that component, there’s a gap between what you do in the gym and what your body needs on the trail.

Exercises like slow step-downs, tempo squats, and controlled split squats help bridge that gap. They train your body to absorb force, maintain alignment, and stay stable on one leg—exactly what’s required when you’re navigating uneven terrain.

A Simple Way to Check Yourself

A quick way to see if this might be affecting you is to try a controlled step-down from a stair or small platform.

As you lower one foot toward the ground, pay attention to what happens. If your knee collapses inward, if you feel shaky or unstable, or if you notice discomfort in the front of your knee, those are signs that your body may not be fully prepared for the demands of downhill hiking.

Knee pain on hikes isn’t something you just have to accept, and it’s rarely just “wear and tear.”

More often, it comes down to how well your body can control load—especially in challenging, real-world situations like descending a trail.

When your muscles are doing their job, your joints are supported. When they’re not, your knees end up taking the hit.

The goal is to build the capacity to handle it.
