Nordic curl negatives are the eccentric-only version of the Nordic hamstring curl, where the athlete lowers the body from the upright kneeling position to the floor under hamstring control and uses the hands (or a partner) to return to the starting position rather than using the hamstrings concentrically.
The term negative refers to the negative (eccentric) phase of the exercise being performed in isolation, deliberately omitting the positive (concentric) return phase. This distinction is not just semantic: performing the eccentric phase in isolation changes the training stimulus, the volume management requirements, and the appropriate application of the exercise.
What Nordic Curl Negatives Are
A Nordic curl negative consists of:
- Starting in the upright kneeling position with ankles fixed
- Lowering the body as slowly as possible toward the floor under eccentric hamstring control
- Catching with the hands (or landing on a padded surface) when the hamstrings reach their limit
- Using the hands to push back to the starting position
- Repeating
The concentric return (pulling the body back up using the hamstrings) is deliberately absent. Each repetition is a fresh eccentric effort from the upright position rather than a coupled concentric-eccentric cycle.
How Nordic Curl Negatives Differ From the Full Nordic Curl
In the full Nordic curl:
The exercise involves both the eccentric descent (the body lowers under hamstring control) and the concentric return (the hamstrings pull the body back to upright). The two phases are coupled and each rep is a complete eccentric-concentric cycle.
In Nordic curl negatives:
Only the eccentric descent is performed under hamstring control. The concentric return is performed by the hands pushing up. Each rep is a pure eccentric effort.
The consequence of this distinction:
Greater eccentric volume per session: Because the concentric return is removed, each set of Nordic curl negatives produces more total eccentric muscle action per rep than would be produced if the athlete used the available concentric capacity to return. For athletes who can perform partial Nordic curls (controlled to approximately 45 to 60 degrees) but cannot return concentrically, negatives allow training to the full available eccentric range without being limited by concentric capacity.
Faster fatigue of the eccentric capacity: Pure eccentric work fatigues the specific eccentric muscle fibres faster than coupled concentric-eccentric work. This means that sets of Nordic curl negatives should typically be shorter (4 to 6 reps) than full Nordic curl sets (8 to 10 reps).
Greater DOMS production: As covered in the nordic curl progression article on this site, the Nordic curl produces more DOMS than most exercises. Negatives, being pure eccentric work, produce even greater DOMS per rep than the full version. Volume must be managed particularly carefully when using negatives.
Why Nordic Curl Negatives Are Specifically Valuable
The Eccentric Overload Principle
Muscles can produce significantly more force eccentrically than concentrically. Research consistently shows eccentric force production is approximately 20 to 30 percent greater than concentric production in most muscle groups. Nordic curl negatives exploit this principle by placing the maximum possible load on the hamstrings during the eccentric phase without the concentric return limiting the training stimulus.
Structural Adaptation Specificity
As covered in the prevent hamstring injuries article on this site, the most important structural adaptation from Nordic curl training is the increase in biceps femoris fascicle length: the muscle fibres become longer and can therefore tolerate greater eccentric loads at longer lengths. This adaptation is specifically driven by eccentric loading rather than concentric loading. Nordic curl negatives, as pure eccentric work, may produce this structural adaptation more efficiently than the full Nordic curl, though the research on this specific comparison is limited.
Bypassing the Concentric Limitation
Many athletes can lower eccentrically (under control) further and more slowly than they can return concentrically. For these athletes, performing the full Nordic curl limits the eccentric training stimulus because they must stop the descent at the point where they cannot return, even though their eccentric capacity would allow them to lower further.
Nordic curl negatives eliminate this limitation: the athlete can lower to the floor under full eccentric control (using the hands to catch only if needed) without being limited by concentric capacity, providing a more complete eccentric training stimulus.
Accessibility for Beginners
For athletes who are new to Nordic curls and cannot yet perform even a slow, controlled partial descent (as described in the early levels of the progression in the nordic curl progression article on this site), negatives provide the very first controlled eccentric exposure. Even a 1 to 2 second eccentric descent before catching constitutes a Nordic curl negative and provides the initial training stimulus.
Who Should Use Nordic Curl Negatives
Athletes beginning Nordic curl training:
Nordic curl negatives are the entry point before the full Nordic curl is possible. Any athlete who cannot perform a controlled descent for at least 2 to 3 seconds should begin with negatives as their primary Nordic curl training method.
Athletes returning after hamstring injury:
The controlled, load-managed nature of negatives makes them appropriate for the late rehabilitation phase, where eccentric loading is needed but the full Nordic curl may be too demanding.
Athletes seeking maximum eccentric overload:
Advanced athletes who can already perform full Nordic curls may use negatives with additional loading (weighted vest) to produce an eccentric overload that exceeds what the unweighted full version provides.
Athletes with insufficient concentric return strength:
Athletes who have developed good eccentric control but not yet the concentric return (a common gap as described in the nordic curl progression article) can use negatives to continue developing their eccentric capacity while the concentric return is separately developed.
Step-by-Step Technique
Setup
Setup is identical to the full Nordic curl. As covered in the how to do nordic curls at home article on this site, ankle fixation can be achieved through a sofa, door anchor, partner hold, or dedicated Nordic curl strap.
Knee padding: Use a yoga mat, folded towel, or dedicated knee pad. The eccentric-only nature of negatives means the knees are not bearing load during the return (the hands take the weight), but the kneeling position during the descent still requires adequate padding.
Hand position: The hands should be positioned ready to catch at chest height or slightly forward throughout the descent. Do not wait until the body is near the floor to prepare the hands: they should be ready to catch at any point during the descent.
The Negative (Eccentric Descent)
- Begin in the tall upright kneeling position with hips in full extension
- From this position, begin lowering the body toward the floor by allowing the knees to extend
- Lower as slowly as possible: the goal is to make the descent last as long as possible
- Maintain the straight body line from knees to shoulders throughout (as described in the how to do nordic curls at home article on this site)
- Lower until either:
- The body reaches the floor (complete descent achieved)
- The hamstrings reach their limit and the hands are needed to catch
Counting the descent duration:
A useful objective measure of progression is counting the seconds of controlled descent per rep. A 2-second descent becomes a 3-second descent, then a 4-second descent, and so on. Tracking the descent time provides clear, objective evidence of eccentric strength development over weeks.
The Return (Hand Push)
- Once the body has reached its lowest controlled point (or the floor), catch with both hands
- Position the hands at approximately shoulder width on the floor
- Perform a push-up to return the body to the upright kneeling position
- The hamstrings do not contribute to the return
- Pause briefly in the upright position to reset before the next repetition
Push-up return speed: The return should be reasonably controlled but does not need to be slow. The return is not the training stimulus in Nordic curl negatives. Getting back to the starting position efficiently allows more time and energy for the next eccentric effort.
Key Technique Cues
Slow is the goal: Every second added to the eccentric descent is progress. The objective is not to lower quickly and catch: it is to make the descent last as long as possible on each rep. This is the fundamental cue that distinguishes a well-performed Nordic curl negative from a poor one.
Hips extended throughout: Identical to the full Nordic curl requirement. Hipping (allowing the hips to flex during the descent) converts the movement from a knee-level eccentric to a hip hinge and significantly reduces the hamstring training stimulus. This is the most important technical requirement and the most common error.
Continuous tension: The hamstrings should be under continuous active tension throughout the descent, actively resisting the fall rather than passively allowing the body to lower under gravity. Think of the hamstrings as brakes rather than the fall being a passive event.
Consistent start position: Each rep should begin from the same fully upright, hips-extended position. Fatigue tends to produce a slightly less upright start position across a set, which shortens the effective range of the eccentric and reduces the training stimulus. Reset to fully upright before each rep.
Common Errors and Fixes
Error 1: Hips Hinging During the Descent
As described in the how to do nordic curls at home and nordic curl progression articles on this site, this is the most common and most consequential error across all Nordic curl variations.
Fix: Film from the side. Maintain the straight line from knees to shoulders throughout. If hinging occurs at any point in the descent, stop the rep at that point and return. Do not continue the descent below the point where hip extension can be maintained.
Error 2: Dropping Rather Than Lowering
What it looks like: The body falls rapidly to the floor in an uncontrolled drop rather than a slow, controlled eccentric descent.
Why this matters: An uncontrolled drop provides minimal eccentric training stimulus because the hamstrings are not producing meaningful resistance against the descent. It also represents the highest injury risk position within the Nordic curl.
Fix: Actively contract the hamstrings throughout the descent, thinking of them as brakes on the fall. If any controlled descent is achievable (even 1 second), that constitutes a valid Nordic curl negative. Progress from the longest achievable controlled descent rather than aiming for the floor immediately.
Error 3: Catching Too Early
What it looks like: The hands catch when the body is at 45 to 60 degrees from upright rather than allowing the descent to continue to a lower point.
Why it happens: Apprehension about the lower range of the descent, or not being aware that greater range is achievable.
Fix: On each session, consciously attempt to lower 5 to 10 degrees further than the previous session before catching. Progressive range extension is the primary measure of eccentric strength development.
Error 4: Not Resetting Fully Between Reps
What it looks like: Each subsequent rep begins from a slightly less upright position than the previous one, with the body angled slightly forward rather than fully upright.
Fix: Pause for 2 to 3 seconds after each push-up return to ensure the body is fully upright and the hips are fully extended before beginning the next descent.
Programming Nordic Curl Negatives
For Beginners to Nordic Curl Training
Nordic curl negatives are the primary training method before the full Nordic curl is achievable.
Volume progression:
- Week 1: 2 sets of 4 negatives (count descent time; any controlled descent qualifies)
- Week 2: 2 sets of 5
- Week 3: 3 sets of 5
- Week 4: 3 sets of 6
- Continue until a controlled descent of 4 to 5 seconds is consistently achieved on all reps
Frequency: Once per week in week 1, twice per week from week 2 onwards.
Transition to full Nordic curl: When 3 sets of 6 negatives with 4 to 5 second descents can be achieved consistently, begin attempting the concentric return. As covered in the nordic curl progression article on this site, the concentric return develops as a separate track.
For Athletes Using Negatives as an Eccentric Overload Tool
Advanced athletes adding negatives to their programme for maximum eccentric stimulus.
Protocol:
- Weighted Nordic curl negatives with vest (10 to 20 kilograms): 3 sets of 4 to 5
- Emphasis on the slowest possible descent under the additional load
- 48 to 72 hours recovery between sessions
DOMS management: Weighted negatives produce significant DOMS even in athletes adapted to regular Nordic curl training. Begin with a conservative load and monitor recovery carefully.
As Part of the Return From Hamstring Injury
Nordic curl negatives are typically introduced in the late rehabilitation phase (6 to 12 weeks post-injury, depending on severity) when the hamstring can tolerate progressive eccentric loading.
Protocol:
- Begin with 2 sets of 4 very controlled negatives with minimal range
- Progress the range and volume conservatively over 4 to 6 weeks
- Transition to full Nordic curls once the negatives can be performed for 3 sets of 6 with a consistent 4 to 5 second descent
Combined Programme
Nordic curl negatives and full Nordic curls can be combined in the same session for maximum eccentric volume:
Session structure:
- Full Nordic curls: 3 sets of 8 (full eccentric and concentric)
- Nordic curl negatives: 2 sets of 4 (pure eccentric, maximum slowness)
The full Nordic curls first ensures the highest quality concentric performance before fatigue. The negatives at the end provide additional pure eccentric volume.
Frequently Asked Questions
Are Nordic curl negatives safer than the full Nordic curl?
For beginners, negatives are often safer because the concentric return is removed, reducing the total workload per rep and allowing better control of the total eccentric dose. However, pure eccentric exercises produce greater muscle damage per rep than coupled exercises, so DOMS management is more important with negatives than with the full version. Starting with very low volume (2 sets of 4) is essential.
Can Nordic curl negatives replace the full Nordic curl?
For people who cannot yet perform the full Nordic curl, negatives are the appropriate replacement. For people who can perform the full Nordic curl, negatives are a complement that provides additional eccentric overload rather than a complete replacement. The full Nordic curl’s concentric return develops additional hamstring qualities (concentric strength, stretch-shortening cycle function) that negatives do not address.
How slow should Nordic curl negatives be?
As slow as possible while maintaining the straight body line and continuous hamstring tension. A practical starting target for most beginners is 2 to 3 seconds per descent, progressing to 5 to 6 seconds as eccentric strength develops. Advanced athletes may achieve 8 to 10 second descents. There is no upper limit on slowness: a slower descent always indicates greater eccentric hamstring strength.
Why do my hamstrings burn so intensely at the bottom of Nordic curl negatives?
The distal biceps femoris (near the outer knee) is under the greatest eccentric load in the final 30 to 40 degrees of the descent, when the hamstrings are near their longest functional length and the body’s leverage is greatest. This burning sensation in the lower outer hamstring is the correct sensation during Nordic curl negatives and indicates the exercise is targeting the most injury-relevant zone of the hamstring. Moderate burning (5 to 6 out of 10) is expected and appropriate. Pain that is sharp, localised, or that persists for more than a few minutes after the session warrants stopping and assessment.
