Treating a hamstring injury starts with stopping when sudden pain occurs and assessing the problem. Adjusted activity and progressive exercise usually follow. Forceful stretching, complete rest or immediate heavy Nordic curls are not universal solutions.
What should you do immediately?
Stop the movement that caused sharp pain. Avoid sprinting, strong stretching and repeated testing. Brief cooling through a cloth may feel soothing, but is not a proven way to speed muscle healing. Compression should not restrict circulation. A pop, extensive bruising, weakness or difficulty walking warrants prompt assessment. Early care focuses on protection followed by appropriate loading. (Hickey et al., 2022)
Which treatment fits your situation?
A clinician assesses symptoms and function; every mild injury does not require imaging. Pain medication does not repair muscle. Discuss suitability with a doctor or pharmacist and do not use it to push through training. Increasing weakness or new sensory changes need reassessment. Sitting-related tendon pain requires different considerations from an acute muscle tear.

How are exercises progressed?
A programme may begin with simple contractions and short movements, then add more demanding knee-flexion and hip-extension exercises. The starting point depends on the injury. The Askling protocol includes the Extender, Diver and Glider: specific rehabilitation options, not a guarantee of fast recovery or an instruction to train immediately at a painful end range. (Hickey et al., 2022)

Track walking, strength, movement control and the response during and after exercise. Then rebuild sport-specific demands, including faster running where relevant. Reduced pain alone does not demonstrate readiness for maximal sprinting. Tendinopathy needs separate attention to compression and tendon loading; Nordic injury-prevention research does not prove that the exercise heals a painful tendon. (Nasser et al., 2021)
Practical next steps
If Nordic curls later fit your assessed training plan, Nordbelt can provide ankle fixation. It is a training aid, not a treatment for pain, cramp or injury. Check the anchor and use a suitable progression; the setup guide explains assembly.
Nordbelt makes one of the best-researched hamstring exercises possible anywhere — without a training partner or expensive bench. At home, in the gym or on the field. Ready in under one minute.

01 THE MOVEMENT
Watch. And see why the Nordic curl works.
Movement progress
20%
Phase 01Feet secured. Lean forward slowly from the knees.
Phase 02Control the descent eccentrically — the muscle gets stronger as it lengthens.
Phase 03Catch yourself with your hands, push back and repeat.
Eccentric training — producing force while the muscle lengthens — targets the moment when the hamstrings are loaded most during sprinting. The Nordic curl trains exactly that.
02 HOW IT WORKS

REAL UNBOXING — THIS IS HOW IT ARRIVES
Thomas PereiraDoctor, sports scientist and co-founder
05 THE STORY
Not a gadget. A frustration solved.
When I suffered a hamstring injury, I noticed how difficult it was to train properly at home without expensive equipment or help from others. That's why I developed Nordbelt.
01
Originated from real injury experience
A real training problem was the starting point — not a marketing idea.
02
Medical and sports science foundation
Further developed with physiotherapists and athletes in the field.
03
Built in Rotterdam
Practical, direct and without unnecessary complexity.
The Nordic Hamstring Exercise is one of the best-studied exercises in sports science. Nordbelt adds no magic — it simply lets you perform the exercise independently, practically and repeatedly. That is exactly the point.
01
Evidence-based exercise
Training programmes that include the Nordic Hamstring Exercise show a clear reduction in hamstring injuries.
02
Build up progressively
Start at a level that suits you and increase load and volume in a controlled way — the 10-week protocol helps you do that.
03
Widely applicable
From football and athletics to fitness and supervised rehabilitation.
Always use a stable anchor point, check every connection and follow a doctor’s or physiotherapist’s advice during injury, rehabilitation or return to play.

A personal question?contact@nordbelt.com
We usually respond within 1 business day.
How do I use Nordbelt? +
Choose a stable door, fitness bench, fence or beam. Close the buckle, adjust the length, check the attachment and start with controlled repetitions.
What is included in the package? +
The Nordbelt, a compact storage bag, a practical guide and a progressive 10-week training protocol.
Do I need a training partner or bench? +
No. Nordbelt is designed for independent training without a large Nordic bench. You do always need a firm, stable anchor point.
Is this suitable for recovery or rehabilitation? +
Nordbelt can support controlled hamstring strengthening. During recovery, decide on timing, load and progression together with your doctor or physiotherapist.
What does shipping cost? +
Standard shipping — Austria: free.
Can I return it? +
You can request a return within 30 days of receipt. The product must be unused, clean and in its original packaging; return shipping costs are paid by the buyer.
Is Nordbelt suitable for beginners? +
Yes. Start with a smaller range of motion and support if needed, keep repetitions controlled and follow the included 10-week protocol. Stop if your technique breaks down or you feel pain.
Which anchor points are safe? +
Only use a solid door, heavy fitness bench, sturdy fence or fixed beam that cannot open, slide or tip. Before every set, pull firmly on the attachment in the same direction as the training load.
How often can I train Nordic Hamstring Curls? +
There is no single frequency that suits everyone. Use the 10-week protocol as a progressive starting point and match volume and recovery time to your level, sporting load and technique.
Where does the 51% fewer hamstring injuries claim come from? +
The 51% refers to programmes that included the Nordic Hamstring Exercise, not to Nordbelt as a product. A systematic review and meta-analysis of 8,459 athletes (van Dyk, Behan & Whiteley, Br J Sports Med, 2019) reported a reduction of up to 51%; individual results are not guaranteed.
