The Single Heel Drop Achilles Stretch targets the Achilles tendon and the calf muscles — gastrocnemius and soleus — by lowering one heel below step level from a raised surface. It is especially effective for improving ankle flexibility, relieving tightness after running or jumping, and reducing the risk of Achilles tendon injuries.
How to do the Single Heel Drop Achilles Stretch
- 1Stand facing a wall or sturdy railing near a step or stair for balance support.
- 2Place the ball of one foot on the edge of the step so your heel hangs freely off the back.
- 3Keep your other foot off the step or lightly resting on it for stability.
- 4Hold the railing or wall lightly with one or both hands.
- 5Keep the working leg straight and your core engaged.
- 6Slowly lower your heel downward below the level of the step, allowing gravity to deepen the stretch through the Achilles tendon and calf.
- 7Hold the stretched position for 20–30 seconds, breathing steadily throughout.
- 8Slowly raise your heel back to the starting position.
- 9Complete all reps on one side before switching to the other foot.
Form tips
- Always hold a railing or keep a hand on the wall — a slip off the step edge can cause injury.
- Lower the heel slowly and under control; avoid dropping it suddenly to prevent overstretching the Achilles tendon.
- Keep the working knee straight to emphasize the gastrocnemius, or bend it slightly to shift the stretch deeper into the soleus.
- Do not lock out the knee aggressively; a soft, unlocked position protects the joint while still loading the calf.
- Wear shoes with a grippy sole or perform the stretch barefoot only on a non-slip surface.
Common mistakes
- Letting the foot roll inward or outward: uneven weight distribution shifts stress away from the Achilles and can strain the ankle ligaments.
- Dropping the heel too fast: a sudden drop creates an uncontrolled ballistic stretch, which increases the risk of micro-tears in the Achilles tendon.
- Not holding support: skipping the railing forces you to tense stabilising muscles, reducing the stretch depth and raising the risk of a fall.
- Holding your breath: breath-holding increases muscular tension and prevents the tissue from relaxing into the stretch.
- Rushing through the hold: cutting the hold short (under 15 seconds) does not give the tendon and calf enough time to lengthen, limiting flexibility gains.
Frequently asked questions
How long should I hold the Single Heel Drop Achilles Stretch?
Hold each repetition for 20–30 seconds and perform 2–3 sets per foot. For chronic tightness or post-run recovery, you can extend holds to 45 seconds.
Can I do this stretch if I have Achilles tendinopathy?
Consult a physiotherapist first. The heel drop is often used as a rehabilitation exercise for Achilles tendinopathy, but the loading protocol (weighted vs. body weight, sets, and tempo) should be guided by a professional to avoid aggravating the tendon.
What is the difference between a straight-leg and a bent-knee heel drop stretch?
A straight working leg places more emphasis on the gastrocnemius (the larger, upper calf muscle), while a slightly bent knee shifts the focus to the soleus (the deeper, lower calf muscle) and the Achilles tendon itself. Both positions are beneficial and complement each other.
When is the best time to do this stretch?
It is most effective after a warm-up or at the end of a workout when tissues are warm. Performing it on cold muscles is generally safe at a gentle depth, but avoid aggressive drops before the body has had a chance to warm up.
Can beginners do the Single Heel Drop Achilles Stretch?
Yes. Beginners should start with a shallow range of motion — only lower the heel to step level or just below — and focus on controlled movement while holding a railing for balance. Increase the depth gradually as flexibility improves.
