If you’ve ever been told to do “3 sets of 10” for an injury, you’re not alone. For decades, that’s been the go-to prescription for exercise rehabilitation. But here’s the interesting part: research shows that the exact number of reps and sets often isn’t the magic ingredient when it comes to recovering from pain.
What really matters is moving in a way that’s safe, consistent, and progressive for you.
The Myth of 3×10
The idea that we need a specific rep and set scheme for pain relief comes largely from traditional strength training. In the gym, 3 sets of 8–12 reps has been shown to help build muscle strength and size. But when it comes to rehabilitation and pain management, the picture is a little different.
• A systematic review by Bertoli et al. (2021) found that across many musculoskeletal conditions, pain relief and functional improvement were seen with a wide range of exercise dosages.
• Similarly, Rhodes et al. (2017) concluded that exercise therapy is effective for low back pain, but the type, intensity, and number of reps were less important than simply doing exercise consistently.
In other words, it’s not the 3×10 itself that works — it’s the fact you’re moving and gradually loading your body.
What the evidence actually says
Research suggests three key points:
- Consistency beats precision. People who stick to exercise programs — regardless of whether they’re doing 2 sets of 15 or 4 sets of 6 — see improvements in pain and function.
- Progression matters more than reps. Studies like Owen et al. (2020) show that gradually increasing load (heavier weights, more challenging movements, or more volume) is linked with better long-term outcomes than staying at the same level forever.
- Individualisation is key. Guidelines (e.g. from the American College of Sports Medicine, 2020) emphasise tailoring exercise to the individual’s tolerance and goals, rather than sticking rigidly to one “ideal” formula.
So, How Many Reps and Sets Should You Do?
Here’s the practical takeaway:
• Start where you are.
If 2 sets of 6 feels good, start there. If 3 sets of 15 with light weights feels better, that’s also fine.
• Challenge without flaring.
The goal is to load your body enough to stimulate adaptation, but not so much that you’re in significant pain for days afterwards.
• Progress gradually.
Over time, increase the weight, the reps, or the sets — whichever feels manageable. This gradual progression is what drives recovery, not the specific number on the page.
When it comes to pain, the number of reps and sets is far less important than the act of moving, sticking with it, and progressing at your own pace. Evidence shows that there’s no “one-size-fits-all” prescription — so don’t worry if your program doesn’t look like 3×10.
Instead, focus on being consistent, listening to your body, and working with your clinician to make steady progress.
