Why rest isn’t always the answer

The Cost of Waiting

“I’ll come back when my knee feels better.”

She said this in March. Then again in May. By August, she’d stopped mentioning the knee entirely. She just stopped coming.

If you’ve been training for any length of time, you’ve either said this yourself or watched someone else disappear with the same promise. I’ll just wait until this goes away. I don’t want to make it worse.

It sounds reasonable. Responsible, even. But here’s what nobody tells you:

If you’re waiting to feel perfect before you train again, perfect isn’t coming.

Especially not after 50.

The Myth of “Better”

In 2018, Serena Williams was 36 years old and dealing with chronic knee issues that had plagued her for months. Imaging showed damage. The conventional wisdom would have been to shut it down and rest. But Williams asked a different question: “What can I still do?”

Not “when will this be fixed?” Not “should I stop?”

What can I still do—right now, with this knee, as it is?

Her team’s answer wasn’t rest. It was modification. They adjusted her training volume, altered her movement patterns, strengthened everything around the knee, and kept her competing. She didn’t wait for the knee to feel perfect. She trained with the knee she had.

She reached four Grand Slam finals after age 35.

Most of us aren’t chasing championships. But if you’re over 50 and you’ve been told to “wait and see” about a cranky shoulder, a stiff hip, or a knee that doesn’t feel quite right, you’re facing the same choice Serena did:

Train with the body you have, or wait for the body you wish you had.

What Actually Happens While You Wait

Here’s the part most people don’t think about:

Your body doesn’t pause while you’re waiting for pain to disappear.

A 2020 study published in The Journals of Gerontology tracked what happens when postmenopausal women stop resistance training—even for just two weeks.

Within 14 days:

• Muscle protein synthesis dropped 30%

• Measurable strength loss occurred in major muscle groups

• Insulin sensitivity worsened

• Bone-loading signals decreased

Two weeks.

Now think about how long most people “wait for it to get better.” A month? Two months? Six?

And here’s what doesn’t show up in any study: the psychological cost. You start questioning whether you can still do the things you used to do. Whether your body is broken. Whether it’s safer to just… not.

The knee that hurt in March? By October, it’s not just the knee anymore. It’s your squat pattern, your balance, your confidence, your entire relationship with your own strength.

This is the hidden cost of waiting.

“But What If I Make It Worse?”

This is the question underneath everything, isn’t it?

What if I train and make it worse? What if I’m damaging something I can’t see?

It’s a reasonable fear. But it’s built on outdated information.

For decades, the medical default for injury was simple: rest. Stop doing the thing that hurts. Wait for it to heal.

Then researchers started asking a better question: What if rest itself is causing harm?

A landmark 2017 study in the British Journal of Sports Medicine found that prolonged rest after injury often leads to worse outcomes—not better ones. Muscles atrophy. Joints stiffen. Movement patterns deteriorate. Pain becomes chronic.

The new model is called optimal loading: continuing to move and load the injured area without aggravating it while progressively building tolerance.

Your body doesn’t need a break from movement. It needs smarter movement.

The Arthritis Question

“Okay, but I have arthritis. Shouldn’t I be protecting my knees?”

If you’re over 50, there’s a decent chance you’ve either been diagnosed with osteoarthritis or you’ve been told “it’s just wear and tear” when something hurts.

And the advice you probably received? Take it easy. Don’t overdo it. Rest when it flares up.

Here’s what the research actually shows:

A 2020 meta-analysis published in Osteoarthritis and Cartilage reviewed decades of studies on knee osteoarthritis and strength training. The conclusion was unambiguous: resistance training is one of the most effective interventions for knee OA. It reduces pain, improves function, and slows progression.

Why? Because cartilage needs load to stay healthy. When you stop loading a joint, the cartilage degenerates faster—not slower.

The Osteoarthritis Research Society International (OARSI) now explicitly recommends exercise as a core treatment for OA. Not as a “nice to have.” As a primary intervention.

But here’s the part that changes everything: the right exercise doesn’t mean ignoring pain. It means modifying load and movement patterns while maintaining strength.

You don’t wait for the arthritis to go away (it won’t). You learn to train with it.

The Pattern Across Every Story

In 2019, Allyson Felix was 33 years old and recovering from an emergency C-section, severe complications, and ankle surgery.

By every measure, she should have stepped away from elite competition. Her body had been through trauma. She had a newborn. She had every reason to wait—or stop entirely.

But Felix didn’t wait for her body to feel like it did at 25. She worked with her medical team to modify her training: pool running when impact was too much, altered sprint mechanics to protect her ankle, and progressive loading to rebuild strength.

She didn’t train through pain. She trained around limitations while rebuilding capacity.

At age 35, she won bronze at the Tokyo Olympics and became the most decorated U.S. track athlete in Olympic history.

Notice the pattern:

Elite athletes don’t wait for perfect. They get expert help and train with what they have.

The question is: why don’t the rest of us get the same support?

What You Should Actually Do

Let’s say you’re 52 and your knee has been bothering you for three weeks.

Here’s what most people do: stop lower body training entirely. Maybe do some cardio. Wait for it to feel better.

Here’s what the research says you should do:

1. Keep training everything that doesn’t hurt

Your upper body, core, and opposite leg can still get stronger. A 2018 study in Sports Medicine found that training the uninjured side of the body actually helps maintain strength in the injured side—a phenomenon called the “cross-education effect.”

2. Modify the painful movement, don’t eliminate it

If squats hurt, can you reduce the range of motion? Lower the weight? Change the stance? The goal isn’t to avoid loading the knee—it’s to find a version of the movement that challenges the tissue without exceeding its current capacity.

3. Progressively reintroduce intensity

This is where most people get stuck. They avoid the movement until it “feels better,” then jump back in at full intensity—and re-injure themselves. Gradual, consistent exposure is what builds resilience.

4. Get expert guidance

This is the step most people skip. And it’s the reason they end up stuck between “train through pain” and “stop everything.”

The Gap No One Talks About

You go to your doctor. They tell you to “take it easy.”

You go to a physiotherapist. They give you exercises on a treatment table that don’t look anything like the movements you actually do in the gym.

You ask your trainer. They’re not sure what’s safe, so they default to: “Let’s just wait until it feels better.”

Meanwhile, you’re Googling at 11 PM trying to figure out whether squatting is bad for your knees.

This is the gap that keeps people stuck.

You need someone who understands both injury and training. Not rehab in isolation. Not programming without context. Both.

A Different Approach

Athletic therapy exists for exactly this reason.

It’s designed to assess pain and movement limitations in the context of your actual training—not on a treatment table, but in the gym, with the movements you actually do.

It’s about answering the question Serena asked: What can I still do?

For many of our clients at Beyond Fitness, this has been the difference between waiting months for something to “get better” and training through with confidence.

And because athletic therapy is often covered under extended health plans (just like physiotherapy), it’s more accessible than most people realize.

The Real Question

Here’s what it comes down to:

You’re 50, 55, 60. You have a knee that’s cranky, a shoulder that’s stiff, a hip that flares up every few weeks.

You can wait for the day when everything feels perfect.

Or you can ask a better question: What can I do today, with the body I have right now?

Because the truth is, if you wait for perfect, you’ll be waiting forever.

And while you wait, you’ll lose strength, bone density, balance, and confidence. You’ll lose momentum. You’ll lose months—maybe years—of progress.

Or you can do what the best athletes in the world do: get expert help, modify intelligently, and keep moving forward.

You Don’t Have to Wait

If something’s been slowing you down—a cranky knee, a stiff shoulder, a hip that doesn’t feel quite right—you don’t have to choose between pushing through pain and stopping entirely. There’s a third option: train smarter, with the right support.

At Beyond Fitness, our athletic therapist works alongside our training team to help clients navigate these exact situations—figuring out what needs modification, what can be progressed, and how to keep building strength even when something doesn’t feel quite right. If you’re already training with us, your coach can help you figure out if that kind of support makes sense for where you’re at. And if you’re not a member, athletic therapy is available to anyone who needs it.

You don’t have to wait for perfect. You just need the right support to keep going.​​​​​​​​​​​​​​​​
