The myth of the perfect exercise
Almost every new patient asks me some version of the same question: “What’s the one exercise I should be doing?”
I understand why people ask. It would be nice if recovery worked that way, like a vitamin you take once a day. But I think this belief, that there’s a single correct exercise or stretch that will fix a given problem, is one of the most common and most unhelpful ideas in this field. It sends people searching for a magic move instead of paying attention to what their body is actually telling them.
Where the idea comes from
I get why it took hold. Search a symptom online and you’ll find a video demonstrating “the best exercise for knee pain” or “the one stretch every runner needs.” These aren’t necessarily wrong exercises. The problem is they’re generic, and bodies aren’t.
Two people can have the same diagnosis and need almost opposite treatment plans. One patient’s shoulder pain might come from a stiff joint that needs mobility work. Another patient with the exact same diagnosis might have too much mobility already, and needs stability instead. Give them the same exercise and you’ll help one and frustrate the other.
What I actually look at
When someone comes in, I’m not just trying to name their pain. I’m trying to understand how they move, what they’re compensating for, and what they need to get back to doing. That means watching how they walk, how they squat, how they reach overhead, before I decide what belongs in their plan.
A rotator cuff issue in a weekend golfer calls for different priorities than the same injury in someone who spreads drywall for a living. The tissue might look similar on an image. The demands placed on it are not.
The trade-off nobody likes to hear
Here’s the part patients don’t always want to hear: individualized treatment takes longer to explain than a one-size answer. It’s easier to hand someone a sheet with three exercises and send them home. It’s harder, but more honest, to say “here’s why these three exercises are right for you specifically, and here’s what would change if your situation were different.”
I’d rather spend the extra few minutes on that explanation. Patients who understand the reasoning behind their plan tend to stick with it longer, and they notice sooner when something isn’t working the way it should.
A better question to ask
Instead of “what’s the one exercise for this,” I’d encourage people to ask “what is my body doing that’s causing this, and what does it need instead.” That question doesn’t have a one-line answer, but it points in the right direction. It also puts the patient in the position of paying attention to their own patterns, which matters long after they’ve finished formal treatment.
I see this play out with athletes recovering from an ACL reconstruction. Two patients can hit the same milestones on paper, same range of motion, same strength numbers, and still need different return-to-sport timelines because of how they land, cut, or decelerate. The number on a chart doesn’t capture that. Watching them move does.
What this means day to day
In practice, this shows up in small ways. I don’t run every low back pain patient through the same core routine. I don’t assume every hip replacement recovery looks like the last one. I built my plans around what I see in the room, not around a template, even when templates would save time.
It also changes how I talk to other providers. When I’m coordinating with a surgeon or an athletic trainer, I’m not reporting a generic protocol. I’m describing what’s specific to that patient, because that’s the information that actually helps someone else make a good decision about their care.
The takeaway
There isn’t a single best exercise for a bad shoulder, a stiff back, or a rebuilt knee. There’s a best exercise for your shoulder, your back, your knee, given how you move and what you’re trying to get back to. If a rehab plan hasn’t been adjusted for you specifically, it’s worth asking why not.
