Ankle Strengthening Exercises To Improve Weak Ankles

Most Popular Exercises

Do your ankles often feel weak, unstable, or painful? If so, you're not alone. 

Weak ankles are a common issue that can affect your balance, mobility, and overall quality of life with multiple sclerosis (MS). But here's the good news: you can strengthen your ankles and feel more confident with simple exercises you can do right from home.

By the way—have we met? Hi, I'm Dr. Gretchen, a physical therapist and MS-certified specialist. I've dedicated my career to understanding Multiple Sclerosis and helping individuals overcome its symptoms. Through my work, I provide MS-specific exercises, easy-to-understand educational videos, and a supportive community to enhance the quality of life for those with MS. Thousands of people have improved their everyday lives using these research-backed strategies, finding renewed hope and confidence in their ability to continue progressing and living life to its fullest.

Today, I want to go through some easy yet effective ankle-strengthening exercises that can help you improve ankle strength, reduce pain, and boost your overall mobility. Let's dive in!

Why Are My Ankles Weak?

Before we jump into the exercises, let's quickly talk about why weak ankles happen in the first place. Often, ankle weakness isn't just about the ankle itself—it's related to what's happening at the joints above and below it. For example:

Knee Pain: If you're experiencing knee pain, it might actually be due to weakness or tightness in your ankle or hip muscles.

Hip Issues: Similarly, hip issues can also contribute to ankle instability.

Everything in our body is connected, so strengthening your ankles often means you'll also be helping your knees and hips at the same time!

Simple Exercises To Strengthen Your Ankles

Here are some of my favorite exercises to recommend to clients to improve ankle strength and stability. These movements are easy to do from a seated position and can make a big difference when done consistently.

Ankle Dorsiflexion (Seated Ankle Lifts)

This exercise targets the muscles at the front of your ankle—the ones responsible for lifting your foot upward (important if you experience foot drop or foot slap).

Exercise Steps:

  • Sit up tall in a chair with your legs straightened out in front of you, feet flat on the ground.

  • Slowly lift both feet upward toward your shins as high as you comfortably can (heels stay on the floor).

  • Pause briefly at the top.

  • Then, slowly lower back down.

Repeat this exercise for 10 repetitions. If doing both ankles together feels challenging, alternate sides (5 repetitions per side). Doing this exercise regularly helps strengthen those important muscles at the front of your ankle and shin.

Seated Clamshells (Hip Strengthening)

Believe it or not, strong hips can help support stronger ankles! Here's how to do seated clamshells:

Exercise Steps:

  • Sit tall with feet flat on the floor and knees together.

  • Keeping your feet touching each other, slowly open your knees apart as wide as comfortable.

  • At the widest point, squeeze your glute muscles (your butt muscles)—you should feel yourself lift slightly off the chair.

  • Relax and slowly close your knees.

Repeat this 10 times. This exercise strengthens hip muscles that support better stability throughout your legs—including your ankles!

Seated Leg Kicks (Knee Extensions)

Strong thigh muscles help support stable ankles too! Here's how to do seated leg kicks:

Exercise Steps:

  • Sit comfortably toward the back of a chair.

  • Slowly straighten one leg out in front of you; hold for about 2 seconds.

  • Then, slowly bend your knee back as far as possible, feeling tension behind your thigh.

  • Hold again briefly before relaxing.

  • If it’s too hard, put something slippery under your foot to reduce friction.

Perform 5 repetitions per side. This exercise targets both quadriceps (front thigh muscles) and hamstrings (back thigh muscles), which help support stable knees and ankles.

Squats (Seated or Standing)

Squats aren't just for athletes—they're fantastic for ankle stability too! Here's how you can safely perform them:

Option A (Seated):

  • Sit tall at the edge of a sturdy chair with feet wide apart.

  • Bend your knees so they are at less than a 90 degree angle

  • Lean forward until your shoulders are over your knees and press firmly down into the ground through your heels—feel those leg muscles activate!

  • Hold for about 3 seconds before relaxing.

Option B (Standing):

  • Stand up straight with feet wide apart.

  • Hinge hips backward first as your shoulders extend beyond your knees, then bend knees slightly into a gentle squat position.

  • Hold briefly before standing back up.

Perform 10 repetitions in total. Squats strengthen many lower body muscles—including hips, knees, calves, and ankles—providing better overall stability.

Don't Forget To Stretch!

Stretching is equally important for improving ankle strength and reducing pain. Here's one of my all-time favorite simple stretches to try:

Figure Four Stretch

  • Sit comfortably in a chair.

  • Cross one ankle over the opposite knee (forming a "figure four").

  • Sit tall and gently hinge forward until you feel a comfortable stretch on the outer hip area.

  • Hold for 20–30 seconds per side.

This stretch helps relieve tightness around hips and thighs—areas that directly influence ankle stability.

How Often Should You Do These Exercises?

Consistency is key! Aim to perform these exercises regularly—ideally every day or at least several times per week—to see noticeable improvements over time. 

Remember: Quality matters more than quantity. Slow movements with control are more effective than fast repetitions. Focus on feeling each exercise in the correct muscle groups mentioned above.

If an exercise feels too challenging or uncomfortable at first, modify it by reducing the range of motion, pause time, or repetitions until you're ready for more intensity.

Above All, Listen To Your Body

Everyone's body moves differently—and that's okay! You might not look exactly like someone else when doing these exercises. The most important thing is that you're feeling them working in the right areas:

  • Front of the shin during ankle lifts

  • Outer hips/glutes during clamshells

  • Thigh muscles working during leg kicks

  • Glutes and thighs during squats

If you're feeling these muscle groups activate clearly during each exercise, you're doing it right—even if it looks slightly different from someone else's form.
