Pain at the Back of Your Thigh? Why It Happens and What to Do

“Nordbelt is easy to secure and feels stable.”

Cem — Trustpilot

Do you notice that you regularly suffer from pain at the back of your thigh? You may experience pain at the back of your leg when walking or sitting, or even pain at the back of your thigh and buttock after a long day at the office. For many people, complaints such as pain in the back of the thigh and even radiating pain to the back of the hip or both legs are unfortunately very familiar. This pain can range from muscle pain to nerve pain in the back of the thigh and can significantly hinder daily functioning.

Hamstring complaints, such as pain in the back of the thigh, are common and can result from various causes, such as overuse, sudden movements, or prolonged inactivity. Especially athletes or people who move intensively on a daily basis, such as runners and football players, are at risk of hamstring problems. Fortunately, there is an effective solution that receives a lot of attention in the scientific literature and that can be easily incorporated into your training routine at home with the Nordbelt: the Nordic Hamstring Curl (van der Horst et al., 2015).

Symptoms and recognition of hamstring pain

Hamstring pain can manifest in various ways. Often, a dull or sharp pain develops at the back of the thigh, which can worsen during walking or sitting. Symptoms of hamstring problems include:

Pain at the back of the thigh when walking or exercising: Especially when accelerating suddenly or when force needs to be applied, this pain can be felt.

Pain at the back of the thigh when sitting: Prolonged sitting can cause increased pressure on the hamstring, which can worsen the complaints.

Radiating pain to the back of the hip and sometimes both legs. This can result from prolonged tension or overloading of the hamstring.

Recognizing these complaints is the first step towards solving them. Studies show that pain at the back of the leg is often associated with reduced stability and strength in the hamstrings. Due to this weakness, the muscles are less able to handle sudden stress, which leads to pain and sometimes even serious injuries. (Opar et al., 2012).

Cause and prevention: Why the hamstring is so prone to pain and injuries

The hamstrings are a group of muscles at the back of the thigh that play an important role in many daily movements, such as walking, running, and jumping. They work closely with the gluteal muscles and the pelvis and ensure that the leg can bend and extend. When the hamstrings are not properly trained, the risk of pain at the back of the thigh can increase significantly. Overuse and a lack of flexibility are some of the main causes of pain at the back of the thigh, especially in intensive athletes. (van der Horst et al., 2015).

According to research, regularly training the hamstrings with specific exercises not only reduces the risk of injuries, but also supports faster recovery in people who already suffer from pain at the back of the leg (Petersen et al., 2011).

The solution: Nordic Hamstring Curl for strong and healthy hamstrings

Researchers agree that the Nordic Hamstring Curl is one of the most effective exercises for strengthening the hamstrings and reducing the risk of hamstring injuries. Several studies show that regular practice of the Nordic Hamstring Curl can reduce the chance of hamstring injuries by no less than 51%, and that the risk of a recurrence of complaints is even reduced by 85% (Al Attar et al., 2017).

Tip: use the handy Nordbelt, a cheap and simple belt to safely use at home with the Nordic Hamstring Curl to start!

The Nordic Hamstring Curl is effective because it trains the hamstrings in a controlled movement that stretches and strengthens the muscles. In this exercise, you start by slowly leaning forward while someone holds your ankles, which allows you to engage and lengthen your hamstrings in a controlled manner. This not only results in strong, but also flexible muscles that can withstand high loads.

Results of the Nordic Hamstring Curl according to research:

1. 50% less risk of new hamstring injuries through consistent application of the Nordic Hamstring Curl (Al Attar et al., 2017).

2. 85% less chance of recurring injuries, which helps to prevent long-term pain at the back of the thigh and the hip (Hickey et al., 2020).

3. Stronger and more stable hamstrings who can better cope with daily load and sports performance, which is important for people with pain at the back of both legs (Jönhagen et al., 1994).

Start easily at home with the Nordic Hamstring Curl with the help of the Nordbelt, ideal for performing this exercise safely and effectively.

01 THE MOVEMENT

Watch. And see why
the Nordic curl works.

Hamstring load20%
  1. Phase 01Feet secured. Lean forward slowly from the knees.
  2. Phase 02Brake eccentrically — the muscle gets stronger as it lengthens.
  3. 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

Secure. Click. Curl.

Go from sports bag to your first controlled repetition in under one minute. The three videos play automatically in sequence — tap a card to replay it.

“It is great to be able to do this exercise by myself.”

11 FAQ

before you order?

Clear information upfront — no fine print hidden behind the buy button.

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?

Shipping costs are calculated at checkout based on the destination and available carrier.

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.
