How to Return to the Gym After an Injury (Without Making It Worse)

The Hardest Part Isn’t Physical

Returning to the gym after an injury is as much a mental challenge as a physical one. You remember what you could do before. You want to get back there as fast as possible. And that urgency is exactly what leads to re-injury.

The number one mistake people make when returning from injury is going back to where they left off. If you were squatting 100kg before your back went, your first session back is not 100kg. It’s not 80kg either. It might be 50kg, and that’s perfectly fine.

The 10% Rule

Once you’ve been cleared to train again, increase load or volume by no more than 10% per week. This gives your body — specifically the injured tissue — time to adapt to increasing demands.

For example, if you start back squatting with 50kg:

Week 1: 50kg
Week 2: 55kg
Week 3: 60kg
Week 4: 65kg

It feels slow. It’s meant to. Your muscles recover faster than your tendons, ligaments, and connective tissue. Just because you feel strong enough to add more doesn’t mean your injury is ready for it.

Start at 50%

A good rule of thumb for your first week back: take whatever you were lifting before the injury and halve it. Use that as your starting point. If it feels too easy, great — that means you’re not risking a setback. You’ll build back up faster than you think.

Discomfort vs Pain

Learning this difference is essential:

Discomfort — a dull awareness of the injured area, muscle fatigue, slight tightness. This is generally okay and expected during recovery.
Pain — sharp, sudden, or increasing sensation that makes you want to stop. This is your body telling you something is wrong. Listen to it.

If an exercise causes pain, stop that exercise. Try a modification. If the modification also hurts, skip it for this session and revisit it next week. There’s no exercise so important that it’s worth re-injury.

Warm-Up Is Non-Negotiable Now

Before your injury, maybe you could get away with a couple of arm swings and jumping straight into your working sets. Those days are over, at least for now.

A proper warm-up for someone returning from injury should include:

5 minutes of general cardio (bike, rower, or walking) to increase blood flow
Dynamic stretching targeting the injured area and surrounding muscles
Activation work for the muscles that support the injured joint
2-3 warm-up sets building gradually to your working weight

PT Tracker’s warm-up generator creates personalised warm-up routines based on which muscles you’re training that day — useful when you’re not sure what to include.

Track Everything

When you’re coming back from injury, data matters more than ever. PT Tracker’s injury log lets you record:

Which exercises caused discomfort or pain
Your pain levels after each session
What modifications worked
How your symptoms change week to week

After a few weeks, you’ll have a clear picture of what your body tolerates and what it doesn’t. That information is invaluable — for you and for any physio you’re working with.

Be Kind to Yourself

This part doesn’t get talked about enough. Coming back from injury is frustrating. Watching other people lift weights you used to handle is demoralising. Feeling like you’ve lost months of progress is genuinely tough.

But here’s the perspective that helps: you’re playing a long game. A few weeks of careful, progressive return is nothing compared to the months you’d lose from re-injury. Every light session is an investment in your future training.

You’ll get back there. Just not all at once.
