Weak ankles are one of the most common reasons runners develop pain in their feet, shins, and knees. The good news is that you can strengthen them with specific exercises and drills that target the muscles, tendons, and ligaments around the joint. The most effective approach combines calf raises, balance work, and resistance band movements done two to three times per week alongside your regular running schedule.
Why Do Runners Need Strong Ankles?
Your ankle is the first structure that absorbs impact when your foot hits the ground. If the muscles around it are weak, the joint becomes unstable. That instability forces your knees and hips to compensate, which often leads to pain in those areas.
Strong ankles also improve your ability to push off the ground with each stride. This makes your running feel lighter and more efficient. Runners with strong ankles are less likely to roll an ankle on uneven terrain, and they tend to recover faster from hard training sessions.
The ankle joint itself is held together by ligaments, which do not strengthen like muscles do. What you are actually strengthening are the calf muscles, the tibialis anterior (the muscle along the front of your shin), and the small stabilizing muscles in your foot. These muscles act as dynamic support for the joint.
How To Strengthen Ankles For Running Exercises Drills: The Core Routine
Start with these five exercises. Do them after a run or on a rest day when your muscles are warm. Aim for two to three sessions per week. You do not need any special equipment beyond a resistance band and a stable surface to hold onto.
Calf raises. Stand with your feet hip-width apart. Hold onto a wall or chair for balance. Rise up onto the balls of your feet as high as you can, pause for one second, then lower slowly. Do three sets of 15 repetitions. When this becomes easy, try doing them on a single leg.
Eccentric heel drops. Stand on the edge of a step with only the balls of your feet on the step. Your heels should hang off the edge. Rise up onto your toes, then lower your heels slowly below the level of the step. This movement strengthens the calf muscle while it is lengthening, which is exactly what happens when you run downhill. Do three sets of 10 repetitions.
Resistance band ankle eversion. Sit on the floor with your legs extended. Loop a resistance band around the outside of one foot and anchor the other end to a fixed object. Turn your foot outward against the band’s resistance. This works the peroneal muscles on the outside of your lower leg, which protect against ankle sprains. Do three sets of 12 repetitions on each side.
Towel scrunches. Sit in a chair with a towel flat on the floor under your foot. Use your toes to scrunch the towel toward you. Do this until the towel is bunched up, then smooth it out and repeat. This strengthens the small muscles in the arch of your foot, which support the ankle from below. Do three sets of 20 scrunches per foot.
Single-leg balance. Stand on one foot with your knee slightly bent. Hold the position for 30 seconds. Progress by closing your eyes or standing on a soft surface like a folded towel. This drill trains the small stabilizing muscles around the ankle to react quickly to changes in your body position.
Balance Drills That Build Ankle Stability
Balance work is different from strength work, but it is just as important for runners. When you run on trails or uneven sidewalks, your ankle has to make constant micro-adjustments to keep you stable. Balance drills train your nervous system to make those adjustments faster.
Start with the single-leg balance described above. Once you can hold it for 30 seconds with your eyes open, try the same position with your eyes closed. Closing your eyes removes your visual reference and forces the muscles in your ankle and foot to do all the work.
Another effective drill is the single-leg squat. Stand on one foot and slowly lower your hips as if you were sitting in a chair. Go down as far as you can while keeping your knee tracking over your toes. Rise back up slowly. This exercise combines balance with strength because your ankle has to stabilize your entire body weight through a range of motion.
A wobble board or balance disc is a useful tool if you have access to one. Standing on an unstable surface for two to three minutes per day challenges your ankle in ways that flat ground cannot. If you do not have a wobble board, standing on a couch cushion or folded yoga mat works as a substitute.
Common Mistakes Runners Make With Ankle Training
The most common mistake is doing too much too soon. Ankle exercises can cause soreness, and pushing through sharp pain is never a good idea. Start with low repetitions and gradually increase over several weeks.
Another mistake is skipping the eccentric movements. Many runners focus only on calf raises, which strengthen the muscle while it shortens. But running involves eccentric loading, meaning your calf muscle is lengthening while under tension as your foot lands and rolls forward. The eccentric heel drop is the most specific exercise for this demand.
Some runners also ignore their foot muscles entirely. The arch of your foot is the foundation of your ankle. If the small muscles in your foot are weak, your ankle has to work harder to compensate. Towel scrunches and picking up marbles with your toes are simple ways to address this.
Finally, do not do ankle strengthening exercises on the same day as a hard speed workout. Your muscles and nervous system need time to recover. Schedule ankle work on easy days or rest days.
How Long Until You See Results?
Most runners notice improved stability within three to four weeks of consistent training. You may feel more confident on uneven terrain or notice that your foot feels more planted with each stride. Visible changes in muscle size take longer, usually six to eight weeks.
Strength gains happen faster than tendon adaptations. The tendons around your ankle remodel slowly, and they need progressive loading over several months to become significantly stronger. Be patient and stay consistent.
If you have a history of ankle sprains, consider continuing ankle strengthening exercises indefinitely. Research shows that people who have sprained an ankle once are more likely to sprain it again. Ongoing strength and balance work reduces that risk.
When To See a Professional
Ankle pain that lasts more than a few days or worsens with activity should be evaluated by a healthcare provider. Pain that is sharp, sudden, or accompanied by swelling or bruising could indicate a ligament tear or fracture.
If you have had multiple ankle sprains and feel like your ankle is unstable even during normal walking, a physical therapist can assess your specific weaknesses and design a targeted program. Some runners benefit from seeing a podiatrist to evaluate their foot structure and gait pattern.
No exercise program can fix every ankle problem. If pain persists despite consistent training, the cause may be something other than weakness, such as arthritis, tendonitis, or a structural issue in your foot.
Frequently Asked Questions
How many times per week should I do ankle strengthening exercises?
Two to three sessions per week is enough for most runners. Doing them more often does not speed up results and can lead to overuse injuries.
Can I run on the same day I do ankle exercises?
Yes, but do the exercises after your run rather than before. Running first ensures your muscles are warm and your form is not compromised by fatigue.
Will ankle strengthening prevent me from rolling my ankle?
It significantly reduces your risk, especially if you also do balance drills. Strong muscles react faster to keep the joint stable, but no exercise can completely prevent an ankle sprain.
Do I need special equipment for ankle strengthening?
No. Bodyweight exercises like calf raises and single-leg balances require no equipment. A resistance band is helpful but optional, and a towel works for foot strengthening.
