Most people do everything they can to avoid tearing a tendon.
One surgeon in Sweden tried to do it on purpose.
👨⚕️ A Swedish Surgeon with a Stubborn Injury
In the mid-1990s, Dr Håkan Alfredson was no ordinary patient. As an orthopaedic surgeon and researcher, he knew exactly how serious Achilles tendon injuries could be. But he also knew one thing for certain: his chronic Achilles pain wasn’t going away.
He tried resting, icing, stretching — nothing worked.
So he asked his colleagues for surgery.
They refused. “It’s not severe enough.”
Frustrated, Alfredson decided to take matters into his own hands.
If they wouldn’t operate, he’d force them to.
🏋️ The Heel Drop Protocol is Born
Alfredson designed a very specific eccentric loading programme using heel drops on a step:
-
Eccentric only: rise up using both feet, then lower slowly on the painful leg.
-
Twice a day, 3 sets of 15 reps — both with a straight leg (to target the gastrocnemius) and a bent knee (to hit the soleus).
-
That’s 180 heel drops per day.
He expected to blow out his tendon.
But instead... the pain gradually disappeared. Completely.
📚 From Failed Plan to Breakthrough Protocol
What began as an attempt to qualify for surgery became one of the most effective tendon rehab methods ever discovered.
In 1998, Alfredson published his findings, and the “Alfredson Protocol” was born. It showed that eccentric loading — lengthening a muscle under tension — could remodel even a stubborn, damaged tendon.
It was a game-changer. Athletes and physios worldwide began using heel drops not just for Achilles tendons, but for plantar fascia, calves, and patellar tendons.
Alfredson proved something radical:
👉 Rest isn’t always the answer.
👉 Pain doesn’t always mean stop.
👉 The right kind of stress can trigger real healing.
💡 What This Means for You
If you’ve been told to “just rest” or “stretch more” — and you’re still hobbling after every run — Alfredson’s story matters.
Because what he proved in a hospital stairwell still applies today:
Tendons want load. They want consistent, controlled stress to adapt and recover.
🔥 The Modern Take: Yoback Makes It Simple
The Alfredson Protocol works — but let’s be honest, 180 heel drops a day is tough to stick with. It’s repetitive, time-consuming, and can be painful.
That’s why we created Yoback.
-
A patent-pending, modular design that stretches and strengthens your whole body, not just your calves, in just 5 minutes.
-
Targets the same root causes of calf pain, plantar fasciitis, and Achilles issues that Alfredson addressed.
-
Sleek, portable, and proven by thousands of runners who finally stopped chasing short-term fixes.
-
It delivers a much deeper and more effective stretch than using a step.
Here’s what runners say when they compare Yoback to the old “step or kerb” approach:
- “The stretching feels so much more than those you can achieve using a kerb or step. Great quality product too.” – David ⭐⭐⭐⭐⭐
- “Whilst I used to do them on the floor / step, this enables a deeper stretch.” – JQ ⭐⭐⭐⭐⭐
- “Oh what a stretch, 10x better than using a step!” – Alison ⭐⭐⭐⭐⭐
- “I was finding calf raises on the step too painful. The Yoback has been a godsend — I can do the exercises without pain, and my plantar fasciitis improved in days.” – Lynne ⭐⭐⭐⭐⭐
