I hear it all the time.

“I would love to do CrossFit, but it will hurt my joints.”

“I don’t want to lift weights because it will bother my joints.”

“I would lift weights, but I have bad joints.”

I’m not a doctor, so if you don’t want to take my medical advice, that’s OK. You can go to Google, your primary care physician, a physical therapist, or even ChatGPT, and they will all tell you the same thing I’m about to tell you:

If you have joint pain, you need to lift weights.

I know what you’re thinking. That sounds counterintuitive. Won’t lifting weights just hurt my joints more?

But here’s the thing: if you have joint pain in your knees, for example, it’s often due to a lack of muscle supporting the knee joint — not because of overuse. When there isn’t enough strength in the muscles around the joint, the joint takes on more stress than it should, and that’s what leads to pain.

When you lift weights and build muscle around that knee joint, it helps take the pressure off the joint itself. That’s when the pain starts to decrease.

It’s the same for shoulders, hips, lower back — really any area that’s giving you trouble. Strong muscles act like armor for your joints. They stabilize you, they absorb impact, and they help you move better.

Now, that doesn’t mean you should grab the heaviest weights you can find and start throwing them around.

The key is controlled, smart strength training that’s appropriate for where you are right now. Good form matters. Proper technique matters. A well-designed program matters.

If you’ve been sedentary for a while, it’s important to start light and focus on movement quality first. Things like squats, lunges, rows, presses, and core exercises — scaled properly — will make a world of difference.

And yes, you might feel some discomfort when you first start moving and strengthening your body. That’s normal. It’s different from injury pain. Your body needs to adapt and rebuild stronger.

The other half of the equation is consistency. You can’t lift weights once a week here and there and expect major results. Strength training needs to be part of your regular routine, just like brushing your teeth or sleeping at night.

If you commit to building strength the right way, over time you’ll notice big changes — not just less joint pain, but better balance, posture, endurance, and overall quality of life.

So the next time you think, “I can’t lift weights because of my joints,” flip that around.
You need to lift weights because of your joints.
