Which Is More Fictional: Unicorns or Tight Hamstrings?

Two weekends ago I was in London teaching a workshop with my friend Luke Worthington.

We had a group of 35 trainers from across the UK (and Europe) eager to learn more about assessment, program design, coaching up common strength movements, and how I rank the Bourne movies.[footnote]Ultimatum, Identity, Supremacy, Jason Bourne, and we’ll just pretend Legacy doesn’t exist.[/footnote]

One of the main umbrella themes we kept hammering home was that, contrary to popular belief, “tight” hamstrings isn’t really a thing.

Labelling the hamstrings as “tight” is often the default scapegoat and blamed for everything from butt wink to low back pain to male pattern baldness. So it wasn’t surprising to see the flabbergasted reactions from the majority of attendees when Luke and I kept repeating our message.

You would have thought Gandalf rode in on a Unicorn yelling “You shall not stretch the hamstrings!” based on people’s facial expressions.

Did Tony Just Say Tight Hamstrings Don’t Exist?

What’s next: Water isn’t wet? Grass isn’t green? Ryan Gosling’s gaze doesn’t penetrate my soul?

Listen, I’m as skeptical as they come whenever anyone in the health/fitness industry uses the words “everyone,” “always,” or “never.”

Those are three words, when used ad nauseam, immediately scream “shady motherfucker with an agenda,” whenever I hear them.

  • It’s never the hamstrings. OR You should never eat past 7 pm.
  • Always avoid gluten. OR If you’re serious about fat loss, always avoid carbs.
  • Everyone must deadlift from the floor. OR Everyone who reads this site is clearly off the charts intelligent and attractive. (<— 100% true).

There are nevertheless exceptions to every rule and circumstance. I’d be remiss not to tip my hat at the notion there are, indeed, people out there who have legitimately tight (or, more to the point, anatomically short) hamstrings.

That being said, I doubt you’re one of them.

I’m not going to sit here and say it’s never the case, but it’s such a rare occurrence that you’re more likely to win an arm wrestling match vs. a grizzly bear than actually having tight/short hamstrings.

Take butt wink for example.

The common culprit is tight hamstrings (photo on the right).

But if we were to discuss (and respect) basic anatomy we’d note the following:

  • The hamstrings are a bi-articular muscle group that cross both the hip and knee joints.
  • My pecs can cut diamonds.
  • As we descend into deep(er) hip flexion – I.e., squat – the hamstrings lengthen on one end (hips) and shorten on the other (knee), for a net change of nada.

But How Can We Tell?

It’s uncanny how many people I’ve interacted with in my career who describe having tight hamstrings, and after telling me they’ve been stretching them for 43 years (<— only a slight exaggeration), are still looking for that one magical stretch to cure them.

My first step is to plop him or her on an assessment table and ask them to perform a simple screen to ascertain whether or not they do, in fact, have tight hamstrings.

It’s called the Active Straight Leg Raise.

You lie the individual supine and ask them to slowly, while keeping one leg cemented to the table or floor, elevate the other off the table while keeping it as straight as possible. They keep going until they feel the first smidgeon of resistance (or you start to see compensations like the pelvis rotating, the foot rotating, and/or either knee start to flex).

An acceptable ROM is anywhere from 70-90 degrees of hip flexion.

A funny thing almost always happens.

Most people pass the screen with flying colors.

Me: “You don’t have tight hamstrings.”

Them: “The fuck outta here! You mean, there aren’t any other stretches I should be doing?”

Me: “Zero.”

Them: “Zero?”

Me: “Yep, zero.”

[Cue crickets chirping]

This finding doesn’t, however, dismiss the fact said person’s hamstrings still FEEL tight.

So, W……..T……….F?

Something is awry.

To peel back the onion a bit more I’ll then implement a brilliant trick I was reminded of by Ottawa based personal trainer, Elsbeth Vaino.

The Bridge Test

 

I’ll have the same individual perform a standard glute or hip bridge. They’ll get into position and then I’ll ask “where do you feel that?”

Many will immediately say “hamstrings.”

I’ll then have them perform a 1-Leg Glute Bridge and ask them to hold that position for 10-15 seconds.

Most don’t last five.

“YOWSA…..my hamstrings cramped up.”

Why?

The body’s #1 hip extensor is the glute max, and if it’s not doing it’s job well the body’s #2 hip extensor, the hamstrings, will pick up the slack.

In all likelihood, for most people most of the time, the hamstrings feel tight because 1) they’re overactive and doing double the work and/or 2) pelvic alignment needs to be addressed (more glutes and anterior core = more posterior pelvic tilt = hamstrings are put on slack).

NOTE: the latter point – hamstrings lengthened due to (excessive) anterior pelvic tilt – is why stretching them only feeds the issue. The tightness many feel is neural in nature, not because of true shortness. Stretching an already lengthened muscle only exacerbates things.

Something Else to Consider: Active End-Range Hip Flexion

To add another nail into the “it’s not the hamstrings” coffin I’ll also take a gander at one’s ability to move their hip into (active) end-range flexion.

This “trick” digs into some of Dr. Andreo Spina‘s work on Functional Range Conditioning (FRC) and is another splendid way to gently tell someone to stop stretching their hamstrings.

 

No diggidy, no doubt.

Final Word

The sensation of tight hamstrings is less about an anatomically short muscle which requires endless hours of static stretching, and more about improving:

  1. Position/alignment of the pelvis via nudging people into a little more posterior pelvic tilt by hammering glutes and anterior core.
  2. Active end-range hip flexion. Allow people to experience this position more often and good things will happen.

Stop…..stretching…..the…..hamstrings.

The Post Where I Prove It’s Not Always Tight Hamstrings

You would think, based off all the alarmist articles I come across on the internet extolling the sentiment, that everyone walking around – you, me, leprechauns[footnote]THEY EXIST![/footnote], everyone – has tight hamstrings.

And as a result, if you do a search on Google, you’ll come across roughly 8, 089, 741 (+/- 41, 903) articles telling you why, how, and when to stretch them.

Tight hamstrings have been to blame for a lot of things, including but not limited to:

  • Back pain.
  • Knee pain.
  • Shoulder pain.
  • Any sort of pain.
  • Male pattern baldness.
  • Global warming.
  • The “death” of Jon Snow.

And while tight hamstring can be the root cause of some of those things, to always put the blame on them is a bit reductionist and narrow-minded to say the least.

In short: It’s the default culprit for lazy coaches and personal trainers to gravitate towards.

To steal a quote from Dr. John Rusin from THIS recent T-Nation article:

“If you’re stretching your hamstrings every day for months (or years) on end without improved flexibility, mobility, movement patterning, or pain relief, it’s not working. And it’s time to get out of this rehab purgatory.

If you aren’t seeing results from stretching, then it’s not only a waste of time, but it may be working against you. The thing is, muscles don’t get longer; they maintain a certain tone or tightness based on neurological impulse. So yes, strategic stretching DOES work in terms of reducing tone and tightness (in the short and long term), but if it hasn’t worked for you by now, it’s probably not going to.”

To steal a quote from myself:

“In order to increase the length of a muscle you need to either 1) lengthen bone (um, ouch!) or 2) in the case of someone who truly presents as short or stiff, increase the total number of sarcomeres in series (which takes a metric shit-ton of stretching).

Ask physical therapist Bill Hartman how long someone really needs to stretch in order to have a significant affect and/or to add sarcomeres, and he’ll tell you the starting point is 2-3, 10 minute holds per day. Working up to 20 minute holds.

That cute 30-second “stretch” you’re doing (most likely incorrectly) isn’t really doing anything.”

Are You “Tight” or Just Out of Whack?

You’d be surprised how often it’s the latter.

Simply put: most people aren’t so much tight as they are “stuck” in a poor position.

It goes back to something physical therapist and strength coach, Mike Reinold, brought up in casual conversation not long ago:

Which is more important to hammer first: stability or mobility?

Those trainers and coaches who swing on the stability side of the pendulum tend to be the overly cautious type who have their clients stand on BOSU balls for 45 minutes.

Those who swing on the the mobility side of things sleep with their copy of Supple Leopard every night.

Neither approach is inherently wrong so much as they’re flawed (if haphazardly assumed as “correct” for every person, in every situation).

If you strengthen (stabilize) in misalignment you develop an imbalance. If you stretch (mobilize) in misalignment you develop instability.

Take someone who presents with excessive anterior pelvic tilt. It’s not uncommon for said person to complain about constantly “tight” hamstrings, and no matter how often they stretch them, they stay tight.

You would think that after weeks, months, or sometimes even years of non-stop “stretching” they’d see some improvement, right?

Wrong.

The reason why they feel tight all the time has little to do with their hamstrings, but rather pelvic positioning.

Unless you address the position of the pelvis – in this case, excessive anterior pelvic tilt – you can stretch the hamstrings until they stop making those shitty Transformers movies (when will it end?) and you’ll never see an improvement.[footnote]No, Michael Bay. NO![/footnote]

Think about it this way: in this scenario the reason why the hamstrings feel tight is because they’re lengthened and firing on all cylinders. By stretching them you’re just feeding into the problem in the first place!

We could easily chalk this up to the classic Lower Cross Syndrome as popularized by Dr. Vladomir Janda and stretch what’s tight (hip flexors, erectors), and that would be a step in the right direction.

Cool.

But I feel for most people, most of the time, that’s not going to solve the problem.

Instead, for the bulk of people, addressing things like anterior core strength (deadbugs, anyone?) in addition to active hip flexion and extension drills, like the Core Engaged Active Straight Leg Raise, is going to be money.

 

Real Life Example Of Not (Really) Tight Hamstrings

Take one of my clients, Dima. For all intents and purposes he’s someone who presents as “tight” AF in the hamstring department.

To throw him under the bus a teeny-tiny bit, if we tested his Active Straight Leg Raise this very minute anyone who’s taken the FMS would grade him the following way:

via GIPHY

Note to Dima: You’re my boy, Blue!

The thing is, as poor as his ASLR appears, I can get more range of motion passively. Meaning, if I were to manually “stretch” his hamstrings I can nudge a bit more ROM.

Since this is the case, wouldn’t it make sense to have him stretch his hamstrings?

Meh, not really.

Now, in Dima’s case, I’m not saying we avoid stretching his hamstrings. He is someone who’s a candidate for doing so (and we do), albeit I don’t prioritize it nearly as much as some coaches/trainers may do.

Instead I have perform stuff like this:

Whaaaaaaaaaaaaaaaaaaaaaaaat

 

That’s some Gandalf type shit right there.

NOTE: Yes, I recognize he’s still unable to get full knee extension, but you can clearly see his ROM improved and the ease at which he got the additional ROM is night and day compared to the start.

All without stretching.

My boy Dean Somerset does a better job than myself explaining the mechanism at play here:

“Part of it is matching the active ability to achieve the position with the passive range of motion that’s available. If they can passively get there, they’re not “tight” or “restricted,” they just may not have the strength or motor control in that specific position, so doing some hip flexion movements can help build context of how to get there so that on their follow up test, they have a better knowledge base of active hip flexion capability to get into.”

In the end, don’t always assume everyone needs to stretch. A little active range of motion in conjunction with TENSION can go a long ways at building context and improving ROM.
