Quick Answer
Best 5 exercises for runners: single-leg calf raise, eccentric heel drop, single-leg balance, tibialis anterior raise (heel walk), ankle alphabet. Frequency: 2–3×/week. When: dynamic exercises (calf raises, heel walks) before runs; eccentric and balance work after runs or on separate days. Key rule: introduce eccentric work (heel drops) gradually — it produces significant DOMS when new. Why it works: the calf-Achilles complex is a spring — stronger, more elastic calves return more energy per stride, improving speed at the same effort level.
Why Runners Specifically Need Calf and Ankle Strength
Runners who only run — without lower leg strengthening — develop cardiovascular fitness faster than their calves and ankles can structurally adapt. The connective tissue in tendons, ligaments, and the ankle joint adapts more slowly than aerobic capacity: a runner can become aerobically capable of much longer or faster runs in 8–10 weeks, while the lower leg structures need 16–20 weeks to fully adapt to that increased load. This mismatch is the primary cause of overuse injuries in runners who increase mileage or pace too quickly.
The lower leg has four distinct functional regions, each requiring targeted attention:
Gastrocnemius and soleus (posterior calf): Produce plantar flexion — the push-off that propels each stride. The gastrocnemius is the more superficial, explosive muscle (power for faster running); the soleus is the deeper, fatigue-resistant muscle (endurance for long runs). Both attach via the Achilles tendon to the heel bone.
Achilles tendon: The connective tissue link between the calf muscles and the heel. Functions as a spring — stores elastic energy during foot-strike and releases it at push-off. Tendon stiffness (in the positive sense) improves running economy. Overloaded without adequate conditioning, it becomes the site of Achilles tendinopathy.
Ankle stabilisers (peroneals, tibialis posterior): The muscles on the lateral and medial sides of the ankle that prevent rolling and maintain joint stability during the stance phase. Weak ankle stabilisers cause excessive pronation or supination, which transmits abnormal forces up the kinetic chain to the knee and hip.
Tibialis anterior (anterior shin): The muscle on the front of the shin that dorsiflexes the ankle — pulls the foot up during the swing phase of running and controls the rate of foot-lowering during landing. Undertrained in most runners; weakness here causes shin splints and contributes to excessive impact loading.
The Exercises: Step-by-Step Instructions
1. Single-Leg Calf Raise (Strength)
How to do it: Stand on one foot at the edge of a step (or flat ground for beginners), with the heel free to drop below the step edge. Hold a wall or railing lightly for balance only — not for load assistance. Rise onto the ball of the foot to full plantar flexion, pause 1 second at the top, then lower slowly over 2–3 seconds. The lowering phase is equally important as the raising phase.
Common error: Bouncing rather than controlling. The controlled lowering is what builds the eccentric strength runners actually need during running.
| Purpose | Sets × Reps | Tempo | When |
|---|---|---|---|
| Strength maintenance | 3 × 15 per leg | 2 sec up, 2 sec down | After runs or separate day |
| Injury prevention baseline | 3 × 25 per leg | Comfortable pace | 3×/week through season |
| Pre-run activation | 2 × 10 per leg (both legs) | Moderate pace | Before runs |
2. Eccentric Heel Drop (Achilles and Soleus)
How to do it: Stand on both feet on a step edge. Rise onto both feet. Then shift all weight to one foot and lower the heel slowly below the step level over 3–4 seconds. Rise back up using both feet. The single-leg lowering under load is the key — this is the eccentric phase that specifically targets the Achilles tendon-calf junction.
Important: This exercise produces significant DOMS when new. Begin with 2 × 8 per leg and build over 2–3 weeks before reaching full maintenance volume. Never add this exercise during a high-mileage peak week.
| Week | Sets × Reps per leg | Lowering tempo |
|---|---|---|
| 1–2 (introduction) | 2 × 8 | 3 sec lowering |
| 3–4 | 2 × 12 | 3–4 sec lowering |
| 5+ (maintenance) | 3 × 15 | 4 sec lowering |
3. Single-Leg Balance (Proprioception and Stabilisers)
How to do it: Stand on one foot with the stance leg slightly bent (never locked). Hold for 20–30 seconds. Progress by closing your eyes, standing on an unstable surface (folded towel, balance pad), or adding small arm movements.
Why it works: Proprioception — the body’s awareness of joint position — degrades with fatigue and is the primary factor in ankle rolls during running on uneven terrain. This exercise trains the neuromuscular reflex that prevents ankle sprains. Cleveland Clinic exercise physiologist Christopher Travers identifies ankle proprioception as the primary protection against ankle weakness effects propagating up the kinetic chain to the knee and hip.
| Level | Hold time | Sets per leg | Progression |
|---|---|---|---|
| Beginner | 20 sec, eyes open | 3 | Stable surface |
| Intermediate | 30 sec, eyes closed | 3 | Stable surface, eyes closed |
| Advanced | 30–45 sec | 3 | Balance pad or folded towel |
| Running-specific | 30 sec + arm swings | 3 | Mimic running arm drive while balancing |
4. Tibialis Anterior Raise (Heel Walk / Shin Strengthening)
How to do it: Stand tall. Lift the balls and toes of both feet off the ground so you are standing only on your heels. Walk forward for 20–30 steps in this position. Alternatively: seated tibialis raise — sit in a chair with feet flat, then repeatedly lift the front of both feet while keeping heels on the ground.
Why runners need this: The tibialis anterior is responsible for controlling the rate at which the foot drops to the ground after heel-strike — the eccentric brake on foot-lowering. Weak tibialis anterior forces the foot to slap down hard, increasing impact loading at the ankle, shin, and knee. This is the direct cause of anterior shin splints in many runners.
Sets/reps: 3 × 20–30 steps heel walk, or 3 × 20 seated raises, 2–3×/week. Include as part of warm-up or cool-down — this exercise does not cause significant fatigue.
5. Ankle Alphabet (Mobility and Neuromuscular Control)
How to do it: Sit in a chair with one foot lifted off the ground. Using the big toe as a “pencil”, trace the letters of the alphabet in the air — A through Z. Exaggerated movements are more effective than small ones. Both directions and full letter shapes engage the complete range of ankle motion. Switch feet. Takes approximately 2 minutes per foot.
Why it works: The alphabet exercise engages every direction of ankle movement — plantar flexion, dorsiflexion, inversion, eversion, and all intermediate angles. It develops neuromuscular control through the full range of motion rather than just the sagittal plane movements most calf exercises target. ASICS identifies the ankle alphabet as one of the most complete single ankle exercises available.
When: Pre-run warm-up or during rest periods. Can be done seated anywhere — on the couch, at a desk, or while watching TV. Daily practice is beneficial and imposes no training stress.
6. Resistance Band Ankle Work (Inversion, Eversion, Dorsiflexion)
How to do it: Sit on the floor with legs extended. Loop a resistance band around the foot:
— Dorsiflexion: Band anchored to a fixed point ahead; pull foot toward shin against resistance. 3 × 15 reps.
— Plantar flexion: Band held in hands; point foot against resistance. 3 × 15 reps.
— Inversion: Band anchored to the outside; turn foot inward against resistance. 3 × 15 reps.
— Eversion: Band anchored to the inside; turn foot outward against resistance. 3 × 15 reps.
Why it matters: Most ankle injuries in runners occur through inversion (rolling outward) — the peroneals on the lateral ankle must be strong enough to resist this motion reflexively. Eversion resistance band work directly strengthens the peroneals. This is particularly valuable for trail runners and athletes with a history of ankle sprains.
7. Bent-Knee Calf Raise (Soleus Isolation)
How to do it: Identical to the single-leg calf raise but with the knee bent at approximately 30–40°. The knee bend removes the gastrocnemius from the movement and isolates the soleus. The soleus is the primary calf muscle in distance running (it is fatigue-resistant and dominates endurance efforts) but is often undertrained compared to the gastrocnemius, which is more prominent and more commonly targeted by standard calf raises.
Sets/reps: 3 × 15 per leg. Include alongside straight-leg calf raises for complete calf conditioning.
8. Single-Leg Hop and Stick (Power and Stability)
How to do it: Stand on one leg. Hop forward (or laterally, or at a 45° angle) and land on the same foot, absorbing the landing through the ankle and knee. Hold the landing position (“stick”) for 2–3 seconds before the next hop. Build from small hops to larger distances over several weeks.
Why it’s running-specific: Every running stride involves a single-leg landing under load. The ability to absorb this landing efficiently and immediately stabilise determines injury risk more than any other factor. This exercise specifically trains the plyometric loading pattern of running in a controlled, progressive way. Include once the earlier exercises feel comfortable — typically after 4–6 weeks of the foundational programme.
Sets/reps: 3 × 8 hops per direction per leg, 2×/week.
Which Exercises Prevent Which Injuries
| Running injury | Primary cause | Key preventive exercises |
|---|---|---|
| Achilles tendinopathy | Repetitive tendon overload without adequate tendon stiffness | Eccentric heel drop (primary), single-leg calf raise, bent-knee raise |
| Shin splints (medial) | Tibial stress from excessive impact and pronation | Tibialis anterior raise, resistance band eversion, single-leg balance |
| Anterior shin splints | Weak tibialis anterior causing foot-slap on landing | Heel walks, seated tibialis raises, band dorsiflexion |
| Ankle sprains | Inadequate peroneal strength and proprioception reflex | Single-leg balance, band inversion/eversion, single-leg hop and stick |
| Plantar fasciitis | Overloaded plantar fascia from calf tightness and weak intrinsic foot muscles | Calf raise (flexibility component), ankle alphabet, gastrocnemius/soleus stretch |
| Runner's knee (PFPS) | Often upstream from ankle/foot pronation weakness | Single-leg balance, resistance band eversion, single-leg calf raise |
| Calf DOMS/strain | Insufficient calf endurance for training volume | Progressive single-leg calf raises (build to 3 × 25), eccentric heel drops |
Runners who experience persistent knee pain should check whether lower leg weakness is contributing. As Cleveland Clinic’s Travers explains, ankle deficiency causes internal tibial rotation that stresses the knee — runner’s knee is often treated at the knee when the source is at the ankle. Our runner’s knee stretches and exercises guide covers the full knee-specific protocol, which pairs effectively with the ankle strengthening programme here. For Achilles-specific issues, our sore Achilles guide covers the full rehabilitation and prevention protocol — the eccentric heel drop in this article is the primary evidence-based treatment for Achilles tendinopathy and is detailed further there.
Weekly Schedule: How to Fit It Into Your Training
| When | Exercises | Duration | Notes |
|---|---|---|---|
| Before every run (warm-up) | Ankle alphabet (1 min each foot), tibialis anterior raises (2 × 20), two-leg calf raises (2 × 15) | 5 min | Dynamic, activating — not fatiguing |
| Strength session 1 (e.g. Tuesday) | Single-leg calf raise, eccentric heel drop, single-leg balance, resistance band work | 15–20 min | After a run or standalone; not before a hard run session |
| Strength session 2 (e.g. Thursday or Saturday) | Bent-knee calf raise, single-leg hop and stick, tibialis anterior raises, ankle balance progressions | 15–20 min | Repeat of session 1 with progression or variation |
| After runs (cool-down) | Static calf stretch (both straight and bent knee), 30 sec each position | 3–5 min | Only static stretching after runs — not before |
This structure integrates directly with a running training week without adding significant fatigue. The two weekly strength sessions of 15–20 minutes each are well within the capacity of runners training 4–6 days per week. Our running frequency science guide covers how to balance training frequency across a week — the strength sessions slot into non-long-run days most naturally, and pairing them with easy Zone 2 runs avoids compromising hard quality sessions. For runners following a complete runner’s strength programme, these calf and ankle exercises should be integrated within the lower body section rather than treated as a separate programme.
Progressions: Building From Beginner to Performance
Lower leg strength work should be progressive — start conservatively and increase load or difficulty over weeks rather than jumping to the hardest variation immediately.
Weeks 1–2 (Foundation): Both-leg calf raises (2 × 15), ankle alphabet daily, tibialis anterior raises (2 × 20), single-leg balance 20 sec × 3 per leg. Keep eccentric heel drops to 2 × 8 per leg — this exercise causes significant DOMS when new and should be introduced carefully.
Weeks 3–4 (Build): Transition to single-leg calf raises (3 × 12 per leg), progress eccentric heel drops to 2 × 12, add resistance band work (all four directions, 2 × 15), extend single-leg balance to 30 sec with eyes closed.
Weeks 5–8 (Maintenance): Single-leg calf raises (3 × 15–20), eccentric heel drops (3 × 15), introduce single-leg hop and stick (2 × 8 per leg), advance balance to unstable surface or running arm drive variation.
Performance phase (ongoing): Progress single-leg calf raises toward 3 × 25 per leg — the target from 220 Triathlon’s physio for athletes doing 10km+ race distances. Add weighted calf raises (dumbbell held in one hand) when bodyweight becomes easy. Include jump rope for 2–3 minutes as a plyometric conditioning addition. Our running faster without more mileage guide covers how lower leg power directly contributes to running economy and cadence improvement — the two drivers of pace improvement without additional volume. Exercises like butt kicks and high knees pair well with the lower leg strength work here as running-specific warm-up drills that also develop leg speed and hamstring activation, complementing the calf and ankle strength focus.
For Older Runners: Why Lower Leg Work Matters More With Age
Ankle proprioception and calf strength naturally decline with age — both faster than general cardiovascular fitness. This explains why ankle rolls, calf strains, and Achilles issues become more common in runners over 50 who haven’t maintained specific lower leg conditioning. The same exercises apply but with longer warm-up periods, more conservative progression timelines (double the week counts above), and greater attention to eccentric work — as tendons become less elastic with age, eccentric loading maintains tendon health more effectively. Our guide for runners over 60 covers the wider adaptations needed for older athletes, and our sprint training for older athletes guide covers how to safely maintain leg power and running speed alongside the foundational strength work here.
The key principle for older runners: do not stop running to rest weak lower legs — maintain running while adding targeted strength work. Deloading often makes tissue more vulnerable, not less. Keep running consistently at appropriate volume while strengthening progressively.

FAQ: Calf and Ankle Exercises for Runners
What calf and ankle exercises are best for runners?
Single-leg calf raise, eccentric heel drop, single-leg balance, tibialis anterior raise (heel walk), and ankle alphabet. These five exercises cover push-off strength (gastrocnemius/soleus), tendon health (Achilles eccentric loading), ankle stability (proprioception), shin protection (tibialis anterior), and full range of motion (ankle alphabet).
How often should runners do calf and ankle exercises?
2–3 times per week for strength maintenance; daily ankle mobility work (alphabet, circles) is beneficial with no downside. Consistency over 3–4 weeks produces measurable improvements in ankle stability and calf endurance.
Do calf and ankle exercises improve running speed?
Yes — stronger calves produce more elastic energy return per stride (improving running economy), and stable ankles reduce compensatory stabilisation costs. Both contribute to faster pacing at the same effort over time.
Can weak ankles cause knee pain in runners?
Yes. Ankle weakness causes tibial internal rotation that stresses the knee joint. Strengthening ankle stabilisers (peroneals and tibialis posterior) is a standard component of runner’s knee prevention and is often the most effective intervention for runners with persistent knee pain that hasn’t responded to knee-specific treatment.
Should I do calf exercises before or after running?
Dynamic activation (calf raises, heel walks, ankle circles) before running. Eccentric and heavy strength work (eccentric heel drops, heavy single-leg raises) after running or on separate days — eccentric loading should not precede a run as it produces fatigue that affects running form and injury risk.
