If you’ve noticed pain, stiffness, or swelling in the back of your ankle — especially first thing in the morning, or during walking, running, and stairs — you may be dealing with Achilles tendonitis, also called Achilles tendinopathy. It’s one of the most common overuse conditions of the lower leg, and it can be frustrating when it starts limiting activities you’d normally take for granted.
If you’ve been searching for PT exercises for Achilles tendonitis, you’re already on the right track: most people recover fully without surgery when they follow a rehabilitation program built around progressive, guided strength. At Embody Health and Performance, we approach Achilles pain the way we approach every injury — by finding the root cause, not just calming the symptom.
What Is Achilles Tendonitis?
Achilles tendonitis (or tendinopathy — the terms are often used interchangeably) occurs when repetitive stress on the tendon outpaces its ability to recover and adapt. Rather than a simple inflammatory injury, it’s better understood as a breakdown in the tendon’s normal repair process — which is why rest alone rarely resolves it, and why a slow, structured reintroduction of load matters so much.
Common symptoms include:
- Pain or stiffness in the Achilles tendon, especially first thing in the morning
- Tenderness when touching the tendon
- Pain that worsens with running, jumping, or prolonged walking
- Difficulty performing heel raises
- Thickening of the tendon in some cases
Insertional vs. Mid-Portion Achilles Tendonitis
Achilles tendonitis generally shows up in one of two spots: mid-portion (a few centimeters above where the tendon meets the heel bone) or insertional (right where the tendon attaches to the heel). The two respond to slightly different exercise emphasis and loading angles, which is one reason a generic exercise list often falls short — a physical therapist can identify which type you’re dealing with and adjust your program accordingly.
Why Does Achilles Tendonitis Develop?
Several factors commonly contribute, including:
- A sudden increase in walking, running, or exercise volume
- Poor lower extremity movement mechanics
- Inadequate recovery between workouts
- Improper or worn footwear
- Age-related changes in tendon health
Understanding why the tendon became overloaded in the first place is just as important as treating the pain itself — it’s the difference between resolving an episode and preventing the next one.
How Physical Therapy Helps Achilles Tendonitis
Physical therapy addresses the underlying causes of tendon pain rather than simply masking the symptom. A well-built rehabilitation program typically includes:
- Progressive strengthening exercises
- Balance and stability training
- A guided walking and running progression
- Activity modification
- Manual therapy when appropriate
- Education on training loads, recovery, and pacing
Progressive loading of the Achilles tendon — gradually asking the tendon to do more, in a way it can tolerate and adapt to — is one of the most effective approaches for long-term recovery. Many rehab programs, including the well-known Alfredson protocol, are built around this same principle of controlled, progressive loading. This is the foundation of adaptive, awareness-driven strength: building capacity in a way that respects where your body actually is right now, not where a generic program assumes you should be.
PT Exercises for Achilles Tendonitis: A Sample Progression
Every rehabilitation program should be individualized, but these exercises to strengthen the Achilles tendon are commonly used under the guidance of a physical therapist.
1. Isometric Calf Holds
May help reduce pain while maintaining muscle activation.
- Stand on both feet.
- Rise onto your toes.
- Hold the position for 30–45 seconds.
- Lower slowly.
- Repeat 4–5 times.
Progress to holding primarily on the affected leg as tolerated.
2. Double-Leg Heel Raises
Begins rebuilding calf strength.
- Stand near a countertop or wall for balance.
- Slowly raise both heels.
- Pause at the top.
- Lower under control over 3–4 seconds.
- Perform 2–3 sets of 10–15 repetitions.
3. Single-Leg Heel Raises
As strength improves, single-leg work provides greater tendon loading.
- Stand on the affected leg.
- Rise onto your toes.
- Slowly lower back down.
- Complete 2–3 sets of 8–12 repetitions.
Quality matters more than quantity — stop if your form breaks down.
4. Bent-Knee Heel Raises
Targets the soleus muscle, an important contributor to Achilles function.
- Slightly bend both knees.
- Perform heel raises while maintaining the knee bend.
- Slowly lower.
- Complete 2–3 sets of 10–15 repetitions.
5. Balance Training
Improves ankle control and lower extremity stability.
- Stand on one leg for 30–60 seconds.
- Progress by closing your eyes or standing on a foam pad.
- Repeat 3–5 times.
Achilles Tendon Exercises to Avoid Early On
Not every exercise belongs in the early phase of recovery. Until your tendon has built some baseline tolerance, it’s generally best to avoid:
- Aggressive static stretching of the calf/Achilles, which can compress and irritate an already-sensitive tendon
- Jumping, bounding, or other ballistic plyometric work
- Sudden increases in hill running or stair-heavy training
- Pushing through sharp, worsening pain rather than mild, tolerable discomfort
A physical therapist can help you determine when it’s appropriate to reintroduce these — timing matters as much as the exercises themselves.
How Much Pain Is Acceptable During Rehab?
Some discomfort during rehabilitation is normal, and it doesn’t mean you’re doing damage. A commonly used guideline:
- Mild discomfort during exercise is acceptable.
- Pain should return to your baseline within 24 hours.
- If pain becomes severe or worsens the next day, the exercise intensity should be reduced.
Your physical therapist will help you find the right level of challenge — enough to drive adaptation, without pushing past what your tendon can currently recover from.
How Long Does Achilles Tendonitis Recovery Take?
Recovery timelines vary based on how long symptoms have been present and how significant the tendon changes are. Many people notice improvement within 6–12 weeks, while longstanding cases may take several months of progressive strengthening. Consistency — not speed — is what actually drives recovery.
How Embody Approaches Achilles Tendonitis
At Embody, we don’t hand you a generic printout of heel raises and send you on your way. Every Achilles tendonitis plan starts with understanding why your tendon became overloaded — your gait, your training load, your footwear, your recovery habits — and builds a progression around that root cause. Sessions run longer than typical PT visits, which gives us the time to teach you the “why” behind each exercise, not just the “how.” We teach; we don’t prescribe. And for clients whose pain makes even standing loading uncomfortable early on, our on-site aquatic therapy pool at The Marsh can offer a lower-impact way to keep the tendon moving and loading while symptoms settle.
When Should You See a Physical Therapist?
Consider scheduling an evaluation if:
- Pain has persisted for more than two weeks
- Walking or climbing stairs has become painful
- You cannot perform a single-leg heel raise
- Symptoms continue to worsen despite rest
- You want a safe, guided path back to running, sports, or an active lifestyle
This article is educational and is not a substitute for individualized medical care. If you experience sudden, severe pain in the back of your ankle or heel — especially with a “pop” sensation or inability to bear weight — seek prompt medical evaluation to rule out a tendon rupture.
Take the Next Step
Achilles tendonitis is frustrating, but it’s highly treatable with the right approach. Progressive strengthening, thoughtful activity modification, and guidance from a physical therapist are the foundation of lasting recovery.

Frequently Asked Questions
A progressive sequence — isometric holds, double-leg heel raises, single-leg heel raises, bent-knee heel raises, and balance training — is commonly used, with a physical therapist adjusting load and pace based on symptoms.
Mid-portion affects the tendon body a few centimeters above the heel, while insertional affects the tendon where it attaches to the heel bone. The two often respond best to slightly different exercise emphasis.
Yes. Most people recover fully through a structured, progressive rehabilitation program without needing surgery.
Early in recovery, it’s generally best to avoid aggressive stretching, jumping/plyometric work, and sudden increases in hill or stair training until the tendon has built baseline tolerance.
Many people improve within 6–12 weeks, though longstanding cases may take several months of consistent, progressive strengthening.
