Progressive tendon-loading exercise, not complete rest, is the first-line rehab for Achilles tendinopathy. Plan for a structured minimum of 12 weeks, load the tendon three or more times a week, and let pain guide your progression: any flare should settle back to baseline within 24 hours. If your pain sits at the heel insertion, you need modifications that limit ankle dorsiflexion.
TL;DR:
- Keep pain at or below 5/10 during loading, and reduce the next session if symptoms remain above baseline the following morning or exceed 24 hours.
- Insertional pain calls for limited ankle dorsiflexion; stop heel drops at step height and consider heel lifts during early rehabilitation.
- Trials found heavy slow resistance and eccentric training both improved pain and function at 12 and 52 weeks; choose the one you can sustain.
- Resume full training only after strength is near symmetrical, high load causes no next day flare, and sport specific drills progress without symptoms.
- If a consistent 12 week program does not provide enough relief, review its dose and discuss shockwave therapy before considering injections or surgery.

What should you do first when your Achilles starts hurting?
Start with relative rest, not total rest. Keep walking and doing daily tasks within a tolerable pain range, cut back the activities that provoke your worst symptoms, and begin gentle loading early. Clinical guidance supports continuing daily activities within pain tolerance and avoiding complete rest, with supervised strength training commonly prescribed for recovery.
Here is why immobilizing backfires. Experts describing conservative management of Achilles tendinopathy note that total immobilization is counterproductive and that fear of movement hinders recovery. The tendon needs managed load to keep its tolerance. A boot or weeks on the couch removes that stimulus, and you return to activity with a weaker tendon than the one that got irritated in the first place.
Practical first steps for the first week or two:
- Swap high-impact work (running, jumping, hill sprints) for cycling, swimming, or flat walking at a comfortable pace.
- Use ice for 10 to 15 minutes after a flare if it eases the ache for you.
- Take a short course of an over-the-counter anti-inflammatory only for a symptomatic flare, and check with your doctor first if you have stomach, kidney, or heart concerns.
- Skip routine corticosteroid injections, which we generally avoid for this problem.
- Start a simple pain log: rate pain during exercise, that evening, and the next morning.
That last habit is the most important one. Clinical guidance suggests keeping pain at 5/10 or less on a visual analog scale during and after loading, and making sure any exacerbation resolves within 24 hours. If the next-morning stiffness or pain is worse than your baseline, you did too much, and you trim the next session rather than quitting rehab.
Pro Tip: Check your Achilles first thing the next morning. Morning pain is the most honest readout of how the tendon handled yesterday’s load.

How do you tell midportion from insertional Achilles tendinopathy?
Midportion pain sits in the body of the tendon, roughly 2 to 6 cm above the heel bone. Insertional pain sits right where the tendon attaches to the heel bone (the calcaneus). The difference matters because insertional tendons are sensitive to compression, so the standard exercises need modifying or they can make you worse.
Randomized trial evidence shows that insertional cases improve more when rehab limits tendon compression, for example by limiting dorsiflexion and using heel lifts, with clinically meaningful VISA-A improvements at 12 and 24 weeks. Distinguishing the two types is crucial for exactly this reason: the same heel drop that helps a midportion tendon can irritate an insertional one.
Simple self-checks you can try at home:
- Location test: Press along the tendon with your thumb and forefinger. Tenderness a few centimeters above the heel points to midportion. Tenderness at the very bottom, where the tendon meets the bone, points to insertional.
- Insertion pressure: Pain reproduced by pressing directly on the attachment suggests insertional involvement.
- Deep dorsiflexion: Pain when you pull your toes toward your shin, such as in a deep squat or a heel drop below the edge of a step, suggests the tendon is being compressed against the heel.
- Swelling pattern: A thickened, spindle-shaped lump in the middle of the tendon is typical of midportion disease. A bony bump at the back of the heel often travels with insertional disease.
- Morning behavior: Both types feel stiff and sore for the first steps of the day. Insertional pain often flares with hills, stairs, and shoes with a stiff heel counter.
Some people have both at once, and other heel problems can mimic these patterns. If your self-check is unclear, or if the pain does not fit either pattern, get an in-person assessment. A clinician can examine the tendon, check your ankle mobility, and decide whether imaging is useful.

What do the four rehab phases look like?
Rehab progresses from managing pain and load, to building strength, to restoring spring and power before a gradual return to sport. You move forward based on how the tendon responds, not the calendar. Clinical frameworks describe this same progression, tying each stage to a type of loading and to function and pain response, as in this tendinopathy practice guideline.
- Phase I: Pain reduction and load management. Isometric holds reduce pain and teach the tendon to tolerate load again. For insertional cases, avoid compression positions. The goal is simply controlled pain and a first taste of tendon tolerance.
- Phase II: Strength and hypertrophy. Heavy slow resistance (HSR) and other isotonic work build capacity. Sessions use multiple sets, with repetitions decreasing as the load rises. The Monash review of key concepts frames this stage as reducing pain while increasing muscle bulk.
- Phase III: Energy storage and power. Once strength and pain criteria are met, you add faster loading such as skipping, hopping, and bounding. The tendon has to learn to store and release energy like a spring.
- Phase IV: Return to sport. Graded, sport-specific work builds volume, and objective criteria decide when you return to full training.
On timing, set realistic expectations. A 2024 clinical practice guideline from the Academy of Orthopaedic Physical Therapy supports exercise sessions three or more times per week, performed as heavily as tolerated, over a minimum of 12 weeks. Many people make major gains by then, but tissue remodeling often lags behind how you feel. Evidence on symptomatic versus functional recovery shows that feeling better does not guarantee the tendon has fully recovered, which is why return to high-impact sport should be gradual.
| Phase | Main focus | Typical loading | Moves on when |
|---|---|---|---|
| I | Pain control, load management | Isometric holds | Pain is stable and calm during daily life |
| II | Strength and capacity | HSR, 3 to 4 sets, 15 down to 6 reps | Heavier loads are tolerated without a next-day flare |
| III | Energy storage and power | Hopping, skipping, faster loading | Plyometric work settles within 24 hours |
| IV | Return to sport | Graded sport-specific drills | Objective strength and pain checks are passed |
How do you perform isometrics, heel drops, and heavy slow resistance?
You have three main tools: isometric holds for pain relief, heavy slow resistance for strength, and eccentric heel drops as a well-studied alternative. A randomized trial comparing eccentric training with heavy slow resistance found that both improved pain and function at 12 and 52 weeks, with HSR tending toward higher satisfaction and better compliance at 12 weeks. Choose the one you will actually do consistently.
Isometric holds (Phase I and flare weeks)
- Stand and rise onto the balls of both feet, or use a single leg once that is comfortable, and hold the top position.
- Do 5 holds of 45 to 60 seconds, 2 to 3 times per day.
- Start at a manageable effort and build it as pain allows.
- Use these for immediate pain relief before activity, and as a fallback on bad days.
Eccentric heel drops (the Alfredson approach)
- Stand on the edge of a step with the balls of your feet on it. Rise up on both feet, then shift your weight to the painful leg and lower slowly.
- Use the original eccentric protocol as your template, and add load with a backpack once it feels easy.
- For insertional cases, stop the lowering at neutral, with the heel level with the step, rather than dropping below it. Limited-range eccentric programs and heel lifts have shown higher patient satisfaction than full-range loading in insertional disease.
- Do them regularly, keeping pain within your monitored limit.
Heavy slow resistance
- Perform multiple sets on a seated or standing calf raise machine, a leg press, or a weighted standing raise, with slow lifting and slow lowering.
- Start around 15 repetitions and progress down to about 6 as you increase the weight. The load for the heaviest sets should feel close to your six-repetition maximum.
- Allow recovery time between training sessions.
- Use a controlled cadence, lifting and lowering slowly without bouncing at the bottom.
Why consistency beats the “perfect” exercise. A systematic review of loading protocols found no single protocol clearly superior, though exercise loading beat passive treatments overall. The Dutch multidisciplinary guideline points the same way: consistency over 12 weeks or more predicts tendon adaptation better than any one exercise mode. Missing sessions costs you more than picking the second-best exercise.
Pro Tip: Put your sets on the calendar like appointments. People who tie rehab to an existing habit, like brushing teeth or the morning coffee, finish the 12 weeks far more often than people who “fit it in.”
How do you know when to progress, hold, or get help?
Progress when the tendon settles within 24 hours of loading, hold when it does not, and get assessed when warning signs appear. The pain rule from clinical guidance is a good starting point: keep pain at or below roughly 5/10 during and after exercise, and make sure any rise returns to baseline within 24 hours. People who follow structured, progressive loading do well, and clinical guidance notes that some studies report up to 82% recovery at 3 months.
Measurable checks to track:
- Pain log: Pain during exercise, that evening, and the next morning. Two or three days of calm numbers means you can add load.
- VISA-A questionnaire: A standard score for Achilles pain and function. Retake it periodically. The Dutch guideline notes that tracking with outcome measures like VISA-A helps keep people on the program.
- Single-leg heel-raise endurance: Count how many controlled raises you can do on each leg, and compare sides.
- Pain-free high-load test: Can you do heavy loaded raises without reactive pain over the next 24 hours?
- Hop tolerance: Once you reach Phase III, can you do a few small hops without a flare?
Hold or step back when: pain exceeds your limit during exercise, stays elevated the next morning, or your single-leg endurance drops from the previous week. Drop one level, such as lower weight or fewer sets, for several days, then try again.
Get a clinician to look at it when you notice:
- New sharp pain, or a sudden pop or snap in the back of the leg
- Swelling that keeps growing
- Night pain that is getting worse
- Pain that does not settle within 24 hours despite lowering your load
- No improvement at all after several weeks of consistent, correctly dosed work
Can footwear, heel lifts, and orthotics help?
Yes, as a support for exercise, not a replacement. Heel lifts reduce compression at the insertion and are often used early, then reduced gradually as loading tolerance improves. The insertional-tendinopathy trial discussed earlier built its modified rehab around limiting dorsiflexion and using heel lifts.
Simple strategies that fit rehab:
- Heel lifts: Place a firm lift in both shoes, so your hips stay level, during the early weeks of insertional rehab. Step down the height gradually rather than removing it all at once.
- Stable heels: Choose shoes with a firm heel counter and a modest heel height. Very flat shoes, barefoot walking, and worn-out trainers can all add strain in the early phase.
- Avoid heel counters that dig in: A stiff rim pressing on the back of the heel can aggravate insertional pain. Try a softer or lower-cut option.
- Off-the-shelf versus custom orthotics: A simple store-bought insert is a reasonable first experiment. If your foot mechanics clearly contribute, such as a collapsing arch or uneven loading, a custom device can alter how force travels through the tendon. Either way, orthotics are an adjunct to your exercise program.
- Reassess regularly: If a footwear change makes pain worse after a few days, stop and rethink it.
We explain how these devices work in our guides to orthotics for foot pain and what custom orthotics are.
What comes next if exercise alone is not enough?
If a solid 12 weeks of well-dosed exercise has not delivered enough relief, the next step is a conversation about adjuncts, not abandoning rehab. Exercise remains the base, and most other options sit on top of it. A review of nonsurgical options for insertional Achilles tendinopathy concluded that most nonoperative treatments lack strong evidence, with exercise (Grade A) and extracorporeal shockwave therapy (ESWT) as notable exceptions.
- ESWT: Shockwave therapy has supportive evidence as a second-line option for some patients, graded B for insertional cases and used as an adjunct in midportion cases. It works best alongside continued loading.
- Injections: Evidence is limited and mixed. Corticosteroid injections are generally avoided around the Achilles. Options like platelet-rich plasma or high-volume injections may be considered in selected, refractory cases after discussion with a clinician. We also offer amnion injections as a nonsurgical option for tendon and ligament injuries.
- Other passive tools: Ultrasound and similar modalities show variable evidence in the narrative review of Achilles tendinopathy management, and keystone care remains eccentric and HSR programs.
- Surgery: Considered after appropriate nonoperative care has failed, commonly after several months. The procedure depends on the pathology and is individualized, so a surgical consultation is about options, not a commitment.
Before escalating, honestly audit your rehab. Was the dose heavy enough? Were you consistent? Did you modify for insertional involvement? Many “failed” programs turn out to be under-dosed ones.
What does a 12-week program look like?
Here is a practical template. Adjust the exercises for insertional cases by stopping heel drops at neutral and keeping heel lifts in your shoes. Always apply the pain rule: at or below 5/10, settling within 24 hours.
- Weeks 1 to 4: Calm and condition. Do isometric holds regularly. Add low-load HSR or modified eccentrics regularly. Log pain daily and cut back the activities that flare you.
- Weeks 5 to 8: Build strength. Raise resistance and gradually lower the repetitions. Allow recovery time between HSR sessions. If pain is calm, add small, controlled plyometrics such as double-leg pogo hops.
- Weeks 9 to 12: Add power. Move to higher-load work, add single-leg hops and bounding, and start sport-specific drills at low volume. For insertional cases, begin trimming the heel lift when loading is well tolerated.
- Every session layout: Warm up with 5 to 10 minutes of easy cycling or walking. Do multiple sets of the main loading exercise. Add accessory work like knee-bent calf raises, hip and glute strengthening, and balance drills. Finish with an easy cool-down. Train regularly, adjusting the frequency to your rehab phase and tolerance.
Treat 12 weeks as the minimum, not the finish line. If your numbers are still improving, keep going.
What should you pass before you return to training?
Return to full training when objective checks, not just a pain-free walk, say the tendon is ready. Because symptoms often improve before tissue remodeling catches up, a gradual return is what protects you from recurrence.
A readiness checklist:
- Single-leg strength is close to symmetrical with the other side on calf raise and endurance tests.
- You can perform a pain-free high-load resistance session, such as heavy raises, with no reactive pain for the next 24 hours.
- Your single-leg heel-raise endurance is strong and repeatable.
- You have completed sport-specific drills at progressively increasing volumes without a symptom flare.
- Your VISA-A score has climbed meaningfully since you began.
- You have a maintenance plan: keep regular loading sessions after you return, to preserve tendon capacity.
Ramp training by small steps, such as adding a little distance or intensity at a time and never both at once.
What do we see most often in practice?
In our experience, the biggest difference between people who recover and people who relapse is dose and consistency, not secret exercises. A simple home progress log and an occasional supervised session keep people honest about load. The two classic mistakes sit at opposite ends: resting far too long, then leaping back into high-impact training before the tendon is ready. Both invite a repeat. The tendon wants steady, boring, progressive work.

FAQ
How long does it take to rehab Achilles tendinopathy?
Plan for at least 12 weeks of consistent loading. The Academy of Orthopaedic Physical Therapy guideline supports sessions three or more times per week over a minimum of 12 weeks. Many people improve a lot by then, but full tendon remodeling can take longer.
What is the best way to heal Achilles tendinopathy?
Progressive tendon-loading exercise, meaning isometrics, heavy slow resistance, or eccentric heel drops, is the best-supported first-line approach. Trials show HSR and eccentric training both work, so choose the one you can stick with. Pair it with load management and pain monitoring.
Does Achilles tendinopathy ever go away?
For most people, symptoms improve substantially with structured rehab. Staying on a maintenance loading routine lowers the chance of a return. Because symptom relief can come before full recovery, a gradual return to sport matters.
Is walking bad for Achilles tendinopathy?
Usually not. Walking within a tolerable pain range keeps the tendon conditioned, and guidance favors continuing daily activities within pain tolerance. If walking pushes pain past your limit or leaves you worse the next morning, shorten it and talk to a clinician.
