What exercises help Achilles tendonitis? The single most evidence-backed exercise is the eccentric heel drop — slowly lowering your heel off a step edge — performed as 3 sets of 15 reps, twice daily, for 12 weeks. This is known as the Alfredson protocol, and it remains the most researched conservative treatment for Achilles tendon pain.
A complete routine typically includes:
· Eccentric heel drops (straight-knee and bent-knee versions) — the core exercise
· Calf and soleus stretching — maintains flexibility and reduces tendon stiffness
· Isometric holds — useful in the early, most painful phase
· Resistance band ankle work — supports surrounding stabilizer muscles
· Gradual return-to-load — bodyweight calf raises before jumping or running resume
Mild discomfort during exercise is expected and generally considered part of the healing process, but sharp or worsening pain is a signal to scale back. Most people notice measurable improvement within 6–8 weeks of consistent practice, with full benefit often taking the full 12-week program.
Why Exercise Works Better Than Rest Alone
Achilles tendonitis (often more accurately called tendinopathy) involves degenerative changes in the tendon's collagen structure, not just simple inflammation. Complete rest can reduce pain temporarily, but it does little to rebuild the tendon's capacity to handle load. Controlled, progressive exercise — particularly eccentric loading, where the muscle lengthens under tension — stimulates collagen remodeling and gradually restores the tendon's ability to tolerate stress.
The Eccentric Heel Drop Protocol (Alfredson Method)
This is the foundation of almost every evidence-based Achilles rehab program.
How to do it:
1. Stand on the edge of a step with your heels hanging off the back.
2. Rise onto your toes using both legs.
3. Shift your weight onto the affected leg.
4. Slowly lower your heel below the level of the step over 3–4 seconds.
5. Use both legs to return to the starting position (this keeps the exercise eccentric-only).
Do this in two variations each session:
· Straight-knee — targets the gastrocnemius (upper calf muscle)
· Bent-knee — targets the soleus (deeper calf muscle)
Dosage: 3 sets of 15 repetitions, in both knee positions, twice per day, 7 days a week, for 12 weeks. That totals roughly 180 repetitions daily across both variations combined.
Mild-to-moderate discomfort during the exercise is common and generally not a reason to stop — but pain that becomes sharp, disabling, or lingers well beyond the exercise session is a signal to reduce load (try a smaller range of motion or bodyweight-only) rather than push through.
Supporting Exercises
Calf and soleus stretches:
Stand facing a wall, step one foot back, and lean forward with the back knee straight (calf stretch) or slightly bent (soleus stretch). Hold each for 30 seconds, 2–3 sets per side.
Isometric calf holds:
In the early, most irritable phase, holding a mid-range calf raise for 30–45 seconds can reduce pain without the repetitive loading of full heel drops — a useful starting point before progressing to eccentric work.
Resistance band inversion/eversion:
Loop a band around your forefoot and slowly move your foot inward and outward against resistance. This strengthens the muscles that stabilize the ankle and reduces compensatory strain on the Achilles.
Progressive return to activity:
Once heel drops are pain-free at full range, progress to standing calf raises, then single-leg raises, then light jogging on flat surfaces before reintroducing jumping, sprinting, or hill work.
During this loading phase, many people find light compression or gentle stabilization helpful for comfort during walking and daily activity. The WHCOOL 3D-Mesh Adjustable Ankle Joint Support Brace, designed specifically to gently stabilize the ankle and Achilles region, can be worn during daily activity between exercise sessions without restricting the range of motion needed for rehab.
How to Progress Safely
· Weeks 1–2: Isometric holds and gentle stretching if pain is severe; begin heel drops if tolerable
· Weeks 3–6: Full eccentric heel drop protocol, both knee positions, daily
· Weeks 6–12: Continue heel drops; introduce standing and single-leg calf raises as strength improves
· After 12 weeks: Gradually reintroduce running, jumping, and sport-specific movement, guided by pain-free performance rather than the calendar
A compression sleeve such as the WHCOOL 7-Zone Compression Ankle Sleeve with Flex Strap can also support the lower leg during this return-to-activity phase, particularly for longer walks or light jogging sessions.
When to See a Doctor
Consult a healthcare provider if pain persists beyond 6–8 weeks of consistent exercise, if you notice a lump or thickening along the tendon, if pain is severe enough to limit walking, or if you feel or hear a sudden "pop" — which can indicate a partial or complete tendon rupture and requires prompt evaluation.
Frequently Asked Questions
Q: How long does it take for Achilles tendonitis exercises to work?
Most people notice reduced pain within 6–8 weeks of consistent eccentric exercise, though the full protocol runs 12 weeks. Chronic cases may take longer and benefit from professional guidance.
Q: Should exercises hurt if I have Achilles tendonitis?
Mild-to-moderate discomfort during eccentric heel drops is common and generally acceptable. Sharp, worsening, or disabling pain is not — reduce the range of motion or load and consult a provider if it persists.
Q: Can I keep running while doing these exercises?
It depends on severity. Mild cases may tolerate light running on flat surfaces if pain stays low and doesn't worsen afterward. More significant cases typically need to pause running until the eccentric program has restored baseline tendon capacity.
Q: Are calf stretches enough on their own?
No. Stretching maintains flexibility but doesn't build the tendon's load tolerance the way eccentric strengthening does. Most effective programs combine both.
Q: Do I need special equipment for these exercises?
No. The core eccentric heel drop only requires a step or stair edge. A resistance band is useful for supporting exercises but not essential to get started.
