Nordic Hamstring Curl Variations To Prehab Against Hamstring Strains

Hamstring injuries are among the most common non-contact injuries in sports. The Nordic hamstring curl exercise, in particular, has been shown to decrease risk by increasing eccentric hamstring strength. In this article, we’re going to cover our favorite nordic hamstring curl variations to prehab against hamstring strains!

How Do Hamstring Strains Occur?

The hamstrings are most commonly injured either during high-speed running and mainly involving the biceps femoris long head or during movements leading to extensive lengthening of the hamstrings (such as high kicking, sliding tackle, sagittal split) often involving the free proximal tendon of semimembranosus. That being said, both types of injuries involve the hamstrings being maximally stretched under high amounts of force.

All injuries occur when tissue capacity cannot meet the demands of the activity. In the case of hamstrings strains, they occur when the hamstrings do not have the adequate eccentric strength (tissue capacity) to control itself while it going into a lengthed position (activity demand). For the hamstrings, this occurs when the hip is moving into flexion and the knee is moving into extension, which is the same position you would get into if you wanted to stretch your hamstrings!

So, how do we reduce the risk of hamstring strains and prehab your body?

Nordic Hamstring Curl Variations

We’re big fans of the Nordic hamstring curl, and have highlighted many variations of it in the past. However, this first one by Skadefri takes the cake. In comparison to the lat pull down variation (2nd clip), this is a lot safer. You don’t need to worry about accidentally landing on your face and it doesn’t require you to find the most appropriate amount of resistance before beginning. In comparison to the push up variation (3rd clip), this doesn’t require nearly the amount of upper extremity (chest/tricep) strength that many are lacking (think of your youth athletes). Furthermore, with this variation you get a great added benefit of some core work. At the fully rolled out position, it’s essentially a plank on a swissball. Similar to the “stir the pot” exercise – without the stirring of course. If you’re more limited by core strength than hamstring strength while doing this variation, then you just discovered a big time limitation aka a weak link that you need to fix with some prehab ASAP.

The best evidence supporting decreased hamstring strain re-injury occurrence is the incorporation of eccentric hamstring exercises.

Researchers have determined through isokinetic testing (via high-tech research laboratory equipment) that a strength imbalance ratio of >20% between eccentric hamstring force production and concentric quadriceps force production resulted in a 4X increase in risk of hamstring injury compared to a normal strength profile ratio (ie equal strength between the hamstrings and quadriceps)!


Nordic Hamstring Curl Variations Without a Partner – Using Lat Machine

Many authors suggest that the hamstrings must be strong enough to eccentrically control and offset the strength of the concentric action of the quadriceps during late terminal swing phase such as when you are performing a kick or doing hurdles. You have two big groups of muscles (hamstrings and quadriceps) on opposite sides of the knee joint. When one muscle (quadriceps) fires and begins moving the knee into extension, what’s going to stop the knee from going into hyperextension? Muscle-wise, that would be your hamstrings.

If your quadriceps are too strong—or hamstrings too weak, rather—when you forcefully move into extension, your hamstrings won’t be able to control the motion and will rip, resulting in a hamstring strain.   If you’re strong enough like Porto Ido here, the Nordic hamstring curl will be cake. If you’re like the rest of the mortals like me, try the second variation using your hands to help control the descent (eccentric part) and push yourself back up (concentric part).

Eccentric Hamstring Strengthening Distally and Proximally

While the Nordic hamstring curl has been studied the most in terms of hamstring strain injury prevention, we believe that in order to truly bulletproof your body, you need to strengthen the hamstrings both distally and proximally. The Nordic hamstring curl occurs when the hip is in a slightly flexed/neutral position, with the knee moving eccentrically from a knee flexed to an extended position. Meaning the distal musculotendinous junction around the knee is primarily working eccentrically while the proximal musculotendinous junction is more or less working isometrically. In theory, this is great for prehab distal hamstring strain. But what about proximal hamstring strains?

In my opinion, to prehab against proximal hamstring strains you need to eccentrically work the hamstrings in the opposite fashion – where the knee is fixed while the hip is moving from an extended to a flexed position. And that is where one of my favorite exercises comes in: The Romanian Deadlift and all of its variations.

RDLs are my favorite. I won’t even try and hide that fact. I recently began playing around with this contralateral offset hold in addition to a contralateral reach.


Hamstring injuries are one of the most common soft tissue injuries in sports. They are especially challenging and frustrating due to the high recurrence rate. This vicious cycle of reinjury and tweaks is because the hamstring wasn’t appropriately managed the 1st time around. It’s time to change the narrative and be proactive with taking care of your hamstrings! This program will expose your hamstrings in a safe and effective manner to prepare you for high-level activities! Learn more by clicking HERE.



Contralateral Offset Romanian Deadlifts + Across Body Reach

The contralateral offset hold further adds to the stability demands of the exercise (that’s already on one leg). By holding the weight in your opposite hand, you are adding a longer lever to the exercise aka it will take more muscle activity to stabilize and move the weight.

Remember, torque (muscle activity in this case) = lever arm (perpendicular distance from weight to axis of rotation) x applied force (weight of the kettlebell).

So we can increase muscle activity and make the exercise harder by either increasing the amount of weight we are holding in our hand (applied force) or by increasing how far away the weight is from our hip joint (lever arm).  Adding the contralateral reach with the weight also acts to further increase the lever arm. But what I really like about the reach is that you can significantly increase the amount of muscle stretch and eccentric load on the glutes. We are getting as much hip flexion, internal rotation, and adduction as we possibly can with this variation at the bottom, all being controlled eccentric by the glutes (and hamstrings). Simplified…but more eccentric muscle stretch = more conducive environment for hypertrophic gains and prehab!

Hamstring Strain Warm-Up

Have you ever strained your hamstring before? You’re not alone! Hamstring strain injuries are among the most common acute musculoskeletal injury in the United States. Even more concerning is that hamstring re-injury rates are extremely high, especially during the first 2 weeks after return to sport. In fact, over 1/3 of hamstring injuries will reoccur during this time. A dynamic warmup is essential for all athletes to prime their body for any activity, especially after recovering from a hamstring injury. This video demonstrates a collection of dynamic movements to adequately warm-up the hamstrings, improve hip flexibility, and promote proximal stability. Shout out to Dr. Nicole Surdyka PT, DPT, CSCS for her triple threat lunge – one of our favorite movements we prescribe to all of our athletes.

Dynamic Hamstring Warmup

“Proximal stability promotes distal mobility.” This adage holds true for every body region and the hamstrings are no exception. Neuromuscular control of the lumbopelvic region is absolutely imperative to all lower extremity biomechanics, especially to optimal hamstring function during normal sporting activities. Improving performance of the proprioceptive system at differing joint angles and body positions through technique-based exercises, balance drills, and plyometric exercises is key. A neuromuscular control program “aims to stimulate the proprioceptive pathways and the processing of such information, with planned and unplanned movements, and, through repetition and practice, alter the neuromuscular response and allow adaptive changes to occur.” A 2009 study by Cameron et al looked at the effects of the “HamSprint Drills” warm up routine on lower limb neuromuscular control of Australian Rugby players.

HamSprint Drills

They found that after 6 weeks of performing the HamSprint drills, the players in the intervention group significantly improved their kinesthetic body awareness and lower limb neuromuscular control in comparison to a usual warm up of stretching and running. The HamSprint Drills were all specifically tailored to the improvement of running technique, coordination, and hamstring function. They included movements like high knee marching, ankle pops, leg cycling, quick support drills, pawing, falling starts, 3-point starts, and squat jump and gos. Here, I demonstrate just a few of the HamSprint Drills.

The Nordic hamstring curl can be an effective exercise to incorporate into your programming to prehab your hamstrings against a future hamstring strain. Even adding 2 sets/week of 4-6 reps may be enough to effectively prehab your hamstrings as this Presland et al 2018 study demonstrated equal fascial length and eccentric strength following high and low volume nordic hamstring curls.

So grab a partner, swissball, or lat pulldown machines as demonstrated in the videos above and get to incorporating the Nordic hamstring curl (and Romanian deadlift) into your programming! Even if that means doing so while playing chest! 🙂

    Hi guys, quick question. This exercise looks great. However, I wonder if it causes any problems to the patellofemeral joint… probably causing pain to anyone suffering from chondromalacia patellae / chondrophatia patellae. Looks like the kneecap gets trapped and acts as a pivot point. If that’s the case, any idea how to modify it to reduce the compressive forces? Cheers, Ben

      It depends, i would try it first. If your knee is sensitive to compression forces and kneeling, then put a pillow underneath which should help. if still sensitive, then the nordic HS curl may not be the best exercise choice for you and you can do other things like swiss ball hamstring curls (see video library for examples)
