Addressing Underloading in Rehab

Helping People Regain Strength With Purpose

Loading rehab with intention

Most people in rehab aren't pushing hard enough — and it quietly stalls recovery.

Let's talk about something we see all the time in rehab: people being underloaded. They're not lifting, moving, or challenging their bodies enough to actually build strength. It's not their fault — it's easy to assume pain means we should hold back. But without just enough challenge, recovery stalls and progress slows.

At AR Physical Therapy, we help people find that sweet spot — where rehab is safe, effective, and actually works — by combining two simple, powerful tools: RPE (Rating of Perceived Exertion) and 1RM (One Repetition Max).

Heading

Making Loading Make Sense
A quick breakdown
RPE
Rating of Perceived Exertion

How hard an activity feels, on a scale from 0 to 10. Simple, intuitive, and surprisingly accurate for guiding effort.

1RM
One Repetition Max

The heaviest weight you could lift once. We never need you to max out — we estimate it from what you can do right now.

Matching Effort to the Moment

RPE and 1RM tend to line up well, so we use them together to make smart decisions. Building strength? We aim for an RPE of 7–8 — the zone where muscles get the stimulus they need. Easing back after surgery or injury? We might start around a 4–5. It's all about matching the effort to the person and the moment.

Why It Matters
Underloading is sneaky

Someone can feel like they're “doing their exercises,” but if those exercises are too easy, there isn't enough stimulus to spark change — meaning slower recovery, less strength, and more frustration. We've seen it too many times. That's why we measure what matters.

We use technology like Kinvent force plates and handheld dynamometers to track force, power, and symmetry in real time. Whether someone is returning from an ACL tear or managing chronic shoulder pain, we know where they are and how far they've come — for all populations, not just athletes.

Reading Your Body
Soreness: what's normal, and when to adjust

Feeling sore after a session isn't a bad thing — it means your body is responding. The difference is knowing normal soreness from pain that signals you've pushed too hard.

Green · 0–3 / 10
Keep going

A little tight or sore, but it fades quickly. You're good to continue.

Yellow · 4–6 / 10
Adjust

Feeling it more, maybe lingering a day or two. We may adjust load or focus on recovery.

Red · 7–10 / 10
Stop & reassess

Sharp, lasting, or increasing pain. Time to stop and re-evaluate the plan.

Most people learn their body's signals quickly with this system. It's empowering — and it keeps progress on track.

Final Thoughts
Rehab isn't about just getting by

It's about rebuilding strength, confidence, and capacity in a way that lasts. If we don't challenge the body, it doesn't adapt. And if we don't measure, we're just guessing.

Whether you're training to get back to sport, back to work, or just back to feeling like yourself, we help you load with purpose. That's how real progress happens.
