You get out of bed, take your first few steps, and feel that familiar stiffness behind your heel.

After walking around, the discomfort improves. However, once you finish a run, leg workout, or long day on your feet, the pain returns.

If this sounds familiar, your Achilles tendon may be struggling to tolerate your current activity level.

Although rest and stretching may provide temporary relief, Achilles tendonitis exercises that progressively build strength can play an important role in long-term recovery.

Here are four exercises to help you rebuild strength and gradually return to walking, running, and training.

What Is Achilles Tendonitis?

The Achilles tendon connects your calf muscles to your heel bone. It helps you push off the ground during walking, running, and jumping.

When the tendon experiences more load than it can currently tolerate, pain and stiffness may develop.

Common symptoms include morning stiffness, tenderness behind the heel, discomfort during calf raises, and pain that returns after exercise.

Persistent Achilles tendon pain is often called Achilles tendinopathy. It can affect the middle portion of the tendon or the area where it attaches to the heel.

This distinction matters because certain exercises may need to be modified depending on where your pain occurs.

Exercise #1: Isometric Heel Raise Holds

If regular calf raises are uncomfortable, isometric heel raises may be a useful starting point.

How to Do It

1. Stand with both feet flat on the floor, holding a wall for balance.
2. Slowly lift your heels a short distance.
3. Hold for 15–30 seconds.
4. Lower your heels and relax.

Start with 2–3 holds if tolerated.

Why it helps: This exercise introduces controlled loading without repeatedly moving the ankle. As your tolerance improves, you can progress toward regular heel raises.

Exercise #2: Seated Calf Raises

Seated calf raises strengthen the soleus, a calf muscle that plays an important role during walking and running.

How to Do It

1. Sit with your knees bent and feet flat on the floor.
2. Slowly lift your heels while keeping your toes on the ground.
3. Pause briefly at the top.
4. Lower with control.

Begin with 2–3 sets of 10–15 repetitions if tolerated.

Once the exercise becomes comfortable, gradually add resistance.

Why it helps: Strengthening the soleus improves your calf’s ability to produce force and supports the Achilles tendon during daily activities and exercise.

Exercise #3: Standing Heel Raises

Standing heel raises build calf strength and gradually increase the amount of load your Achilles tendon can tolerate.

How to Do It

1. Stand with both feet flat on the floor.
2. Slowly rise onto the balls of your feet.
3. Pause briefly at the top.
4. Lower your heels with control.

Start with 2–3 sets of 8–12 repetitions if tolerated.

As your strength improves, gradually increase the repetitions or add resistance.

Important: If your pain is directly where the Achilles attaches to the heel, avoid dropping your heels below the level of a step unless your physical therapist recommends it. This position may aggravate insertional Achilles tendinopathy.

Exercise #4: Single-Leg Heel Raises

Once double-leg heel raises become comfortable, single-leg heel raises provide a greater strengthening challenge.

How to Do It

1. Stand on one leg near a wall or counter.
2. Slowly lift your heel as high as you comfortably can.
3. Pause briefly.
4. Lower with control.

Begin with a few quality repetitions and gradually increase as tolerated.

Why it helps: Single-leg heel raises build strength and endurance while allowing you to identify differences between your legs.

However, completing this exercise without pain does not automatically mean your tendon is ready for sprinting or jumping. Those activities require further progression.

How Much Pain Is Acceptable During Exercise?

Some mild discomfort may be acceptable during a structured Achilles rehabilitation program.

However, you should not push through significant pain or repeatedly perform exercises that leave your tendon substantially worse afterward.

Pay attention to how your Achilles feels during exercise, later that day, and the following morning.

If your morning stiffness or pain increases noticeably, you may need to reduce the exercise intensity, volume, or frequency.

Why Rest and Stretching Alone May Not Be Enough

Temporarily reducing painful activity can help settle symptoms, but rest does not automatically rebuild the strength needed to return to running or training.

Progressive tendon-loading exercises are a central part of rehabilitation for many people with Achilles tendinopathy.

Stretching may also help when mobility is limited, but aggressive stretching can aggravate symptoms in some people, particularly when pain occurs at the tendon’s attachment to the heel.

The goal is to gradually increase your tendon’s ability to handle activity rather than avoiding loading indefinitely.

When Can You Return to Running?

Walking without pain is a positive step, but running places greater demands on your Achilles tendon.

Before returning, consider whether you can tolerate walking, perform controlled heel raises, and complete your strengthening exercises without significantly worsening symptoms.

A gradual return-to-running program may begin with short running intervals separated by walking.

As your tolerance improves, you can gradually increase running time, mileage, and intensity.

Your response during exercise and the following morning should help guide progression.

When Should You See a Physical Therapist?

If Achilles pain keeps returning whenever you run, lift, or increase your activity, a physical therapist can assess your calf strength, ankle mobility, tendon-loading tolerance, and movement mechanics.

Seek prompt medical evaluation if you experience a sudden pop behind your ankle, significant weakness, or difficulty pushing off your foot after an injury.

Build a Stronger Achilles at Physiopros

Long-term Achilles rehabilitation involves more than temporarily relieving pain.
