How To Perform The Single Leg Heel Raise Test?

You stand on one foot and rise up onto your toes as high as possible. That is the single leg heel raise test in its simplest form. It measures calf muscle strength, endurance, and ankle function. To perform it correctly you stand barefoot against a wall for balance, lift one foot off the ground, and press up through the ball of your standing foot as high as you can go.

How To Perform The Single Leg Heel Raise Test Correctly?

Start by standing barefoot near a wall. Place your fingertips on the wall for light balance only — do not lean on it. Lift your non-test foot off the ground so you balance entirely on the leg being tested.

Keep your knee straight but not locked. Your ankle should be the only joint moving. Press through the ball of your foot and raise your heel as high as possible. Lower it back down slowly until your heel touches the floor. One repetition is one full up-and-down movement.

Perform the movement at a steady pace. A common rhythm is one heel raise every two seconds. Most clinicians use a metronome set at 60 beats per minute — up on one beat, down on the next. Continue until you cannot complete a full range of motion, you stop for rest, or your form breaks down.

What Does the Single Leg Heel Raise Test Measure?

This test primarily measures the strength and endurance of your gastrocnemius and soleus muscles — the two muscles that make up your calf. It also tests your ankle plantar flexors, which are the muscles that point your foot downward. The ability to perform a full range of motion tells you about your Achilles tendon function and ankle joint mobility.

Research published in the Journal of Orthopaedic & Sports Physical Therapy has shown that the single leg heel raise test is a reliable way to assess calf muscle function after injury or surgery. It is commonly used after Achilles tendon repairs, ankle fractures, and calf strains. The number of repetitions you can complete gives a rough measure of muscular endurance.

There is no single universal cutoff for a “normal” score. Studies have found that healthy adults under 50 can typically perform 20 to 30 single leg heel raises before fatigue sets in. Older adults and people recovering from injury often fall well below that range. What matters more is comparing your score to your uninjured leg or tracking changes over time.

How Many Repetitions Should You Be Able To Do?

Most healthy adults can perform 20 to 30 repetitions on one leg. A 2018 study in the journal Physical Therapy in Sport found that the average number of heel raises for healthy adults aged 20 to 40 was about 25 on each leg. The numbers drop with age. People over 60 often manage 10 to 15 repetitions.

Your score depends on several factors. Body weight matters — heavier individuals typically do fewer repetitions. Calf muscle size and training history also play a role. Runners and dancers often score higher. People who sit most of the day usually score lower.

A difference of more than 10 percent between your left and right leg may signal a problem. For example, if you can do 20 raises on your left leg but only 12 on your right, that gap warrants attention. It could mean weakness, poor motor control, or an underlying injury on the weaker side.

What Are the Most Common Mistakes People Make?

The biggest mistake is using your hands to push off the wall. Your fingertips should rest on the wall for balance only — not to lift your body weight. If your knuckles turn white from gripping, you are cheating. The test loses its value if you assist with your arms.

Another common error is bending your knee during the movement. A bent knee shifts the work from your gastrocnemius to your soleus and changes what the test measures. Keep your knee straight throughout the entire repetition. If you feel your knee bending, stop and reset.

Many people also rush the movement. Fast, shallow heel raises do not challenge the full range of motion. You must lower your heel all the way to the floor between each repetition. Partial reps do not count. If you cannot touch your heel down, you are not completing a full repetition.

Losing balance is normal, especially on your first few attempts. But if you constantly grab the wall or hop to regain balance, your score will not reflect true calf strength. Practice the test a few times before recording your result. Most people improve their score by 2 to 5 repetitions simply by getting comfortable with the movement.

When Should You Use This Test?

Physical therapists use the single leg heel raise test most often after lower leg injuries. It is a standard part of return-to-sport testing after an Achilles tendon rupture. Surgeons often use it to measure recovery progress after ankle surgery. The American Physical Therapy Association includes it in clinical guidelines for Achilles tendinopathy and plantar fasciitis.

You can also use this test at home to check for calf weakness or asymmetry. If you notice one calf is visibly smaller than the other, the heel raise test can confirm whether strength matches appearance. A difference of more than 5 repetitions between legs is worth mentioning to your doctor or physical therapist.

The test is not useful for everyone. People with acute ankle sprains, severe Achilles tendon pain, or recent fractures should not attempt it without medical guidance. If you feel sharp pain during the movement, stop immediately. Dull muscle fatigue is expected. Sharp pain is not.

How To Improve Your Single Leg Heel Raise Score?

If your score is lower than you want, the fix is straightforward: do more calf raises. But not just any calf raises. You need to train the same movement you are testing. Stand on one leg, keep your knee straight, and raise your heel as high as possible. Lower slowly. Repeat.

Start with three sets of as many repetitions as you can manage on each leg. Rest 60 seconds between sets. Do this every other day. Most people see improvement within two to four weeks. A 2020 study in the Journal of Strength and Conditioning Research found that doing heel raises three times per week increased calf raise endurance by 30 percent in six weeks.

You can also add weighted calf raises once your bodyweight version becomes easy. Hold a dumbbell in one hand and perform the same movement. But do not add weight until you can complete at least 20 clean repetitions on one leg. Loading a weak calf too early increases injury risk.

• Do single leg calf raises every other day
• Focus on full range of motion — heel touches floor each rep
• Keep your knee straight throughout the movement
• Use the wall for balance only, not support
• Track your reps each session to see progress

What Do the Results Actually Tell You?

A low score on the single leg heel raise test does not automatically mean you have a problem. It could simply mean you have weak calves from sitting too much or not training them directly. Many people have never done a single leg calf raise in their life. Their first attempt is often low simply because the movement is unfamiliar.

What matters more is the pattern. If both legs score equally low, you likely have general calf deconditioning. If one leg scores much lower than the other, that asymmetry points to a specific issue on the weaker side. If your score drops over time, that decline may signal worsening tendon health or muscle atrophy.

The test is also useful for monitoring recovery. If you had an Achilles injury and could only do 3 heel raises six weeks ago, and now you can do 12, that is real progress. The numbers give you an objective measure that your subjective feeling of “getting better” cannot replace. Research from the British Journal of Sports Medicine confirms that the heel raise test is one of the most reliable functional tests for tracking Achilles tendon recovery.
