Coming back from an injury without restarting

I tore a calf at 43, running intervals on a Tuesday morning. Felt like someone shot me in the back of the leg with a small calibre. I limped a kilometre home and spent the rest of the day Googling.

What I read was mostly wrong. Or at least, mostly outdated.

The old advice was rest. Total rest. Wait until it stops hurting, then ease back in. The newer evidence-based protocols, the ones the sports physios I've worked with use, look almost the opposite. Relative rest, early loading, structured return.

Six weeks later I was back to short intervals. Not because I'm tough. Because I followed the protocol instead of my instincts.

What the evidence suggests now

The shift in injury rehab over the last 15 years has been from "rest until pain stops" to "load appropriately to the tissue's tolerance." The phrase to hold onto is relative rest, not full rest.

A few principles the literature converges on:

• Tissue heals faster under appropriate load than under no load
• Pain isn't a perfect signal, but persistent or worsening pain is
• Cardiovascular fitness can be maintained through cross-training during recovery
• Identifying and addressing the cause matters more than treating the symptom

Full bed rest, for almost any musculoskeletal injury, is now considered counterproductive. The exception list is short and your physio will know it.

The framework I now use

When something goes (and after 40, things go more often), I run a four-phase mental checklist. It's roughly the structure most sports physios use, simplified.

Phase 1: Calm the tissue (days 1 to 7)

• Reduce load on the injured area (don't eliminate it entirely)
• Maintain general fitness through low-impact alternatives (swim, bike, upper body)
• See a physio early, not in week three when it's still grumbling
• Sleep more, eat enough protein, hydrate

Phase 2: Restore range and basic strength (weeks 1 to 4)

• Begin loaded movement at low intensity (isometrics first, then slow concentrics)
• Re-establish range of motion gradually
• Cross-train at moderate intensity (whatever doesn't aggravate)
• Track pain on a 0 to 10 scale, daily

Phase 3: Reload (weeks 3 to 8, depending on severity)

• Progressive overload back into the injured pattern
• Build to roughly 80% of pre-injury capacity before adding speed or impact
• Watch for compensations (the other leg, the other shoulder, doing too much)
• Re-introduce the activity that caused the injury, last and slowest

Phase 4: Return and stress-test (weeks 6 to 12+)

• Add the speed, impact, or volume that the original activity demands
• Sport-specific or load-specific rehearsal
• Continue prehab exercises permanently (not as a phase, as a habit)

The timeline is approximate. Severity, age, sleep, and how stubborn you are will all push the numbers around.

The traps I keep seeing

The men I know who reinjure themselves repeatedly tend to make the same handful of mistakes.

• Returning to full intensity the moment it stops hurting (pain ends before tissue heals)
• Skipping Phase 2 because it feels boring (it is, that's not the point)
• Ignoring the cause (form, volume, surface, load progression)
• Stopping the rehab exercises after they "fixed" the issue
• Not seeing a professional because they think they can self-diagnose

I've made all five. I now have a calf raise routine I'll do for the rest of my life because the alternative is tearing something every two years.

What I keep training while I rehab

The trap is to do nothing. The other trap is to do the wrong everything. A workable middle:

• Strength work on the uninjured limbs (single-arm and single-leg work shines here)
• Cardiovascular work that doesn't load the injury (bike for ankles, swim for shoulders, rower for knees)
• Mobility work for the whole chain, not just the injured spot
• Nutrition and sleep, deliberately tightened up

The cardiovascular maintenance especially matters. A six-week injury can cost you a year of aerobic base if you do nothing. The bike, used three or four times a week at Zone 2, will hold most of it.

When to escalate

The general rule of thumb I use:

• Pain that doesn't change in 7 days: see a physio
• Pain that worsens despite rest: see a GP or sports doctor
• Any joint that "gives way," locks, or swells significantly: imaging may be warranted
• Loss of function (can't load it at all): immediate professional input

The physio appointment in week one is almost always cheaper than the surgery in year three.

The mental side

Injuries hurt your training and your head. The men I know who recover well share a habit. They reframe the rehab as the training. The Phase 2 boring isometrics aren't a punishment. They're the work that lets the Phase 4 sprinting happen.

The body in front of you, this week, is the one you train. Not the one you had two months ago.

(See an accredited exercise physiologist or sports physiotherapist for any injury that isn't trivially resolving. Generic internet protocols, including this one, are starting points, not substitutes for hands-on assessment.)

Load the tissue. Trust the protocol. Come back better.
