Is stretching the answer part 2: Your hamstrings are tight, but are they short?

I gave a talk at a local Running Room last week, where I opened by asking if anyone has tight hamstrings. Guess how many raised their hands. If your guess is about 90%, you’re right. I then asked half the attendees to lie on their backs while the other half observed. I instructed those on the floor to place their arms on the floor at their sides with palms facing up, and straighten their legs with toes pointed toward the ceiling. I then asked them to keep both knees straight and lift one leg up as high as they could.

Of the 15 or so legs that were in the air, 2 were at about a 45 degree angle from the ground, while the rest were 90 degrees plus or minus a few degrees. I had the observers and doers switch places and repeat, and not surprisingly (to me), the result was basically the same. Approximiately 90% of the people in the room feel that they have tight hamstrings, but based on an active straight leg raise test, only about 10% of the people in the room actually have short hamstrings.

Which begs the question: If your hamstrings feel tight, but aren’t short, is stretching going to help?

We stretch to increase the length of muscles, but if our muscles are already long, what is stretching accomplishing? And more importantly, if the muscle is already long, why does it feel tight?

Maybe it feels tight because it’s overworked. Every muscle in the body is capable of doing more than one task, and every task that the body does can be done by more than one muscle. It’s quite a spectacular design from an engineering perspective. Imagine if your car had the equivalent of a spare tire for every single part pre-installed, and the car was smart enough to automatically engage that extra part without intervention if the main part failed. That’s basically your musculoskeletal system. It’s amazing when you think about it. The thing we have to consider is that the back-up system is not as efficient as the main. This is an engineering reality for most systems, and a reality that exists in us.

The glutes are your body’s primary hip extensors, but the hamstrings are also capable of hip extension. If you’re a runner, you extend your hips with every stride. How many hip extensions would that be over the course of a 10 k?

The transition from the front to the back leg in a running stride is hip extension.
The transition from the front to the back leg in a running stride is hip extension.

What if the reason so many runners have hamstrings that feel tight is that the glutes aren’t doing their job, leaving the backup system – the hamstrings – to do the full load?

To see if this might be the case with this group, I again asked half the group to lie on their backs on the floor and half to observe. This time I instructed them to bend their knees and place their feet on the floor about hip-width apart, with heels about a foot away from their butt, and hold their hands together above their chests with arms straight. I instructed them to push their hips off the floor and drive one knee toward the ceiling. I had them hold this position for about 15 seconds.

During this time a few people dropped their hips back to the floor because their hamstrings started to cramp. At about the 10 second mark, I asked everyone else where they felt it, and then we repeated on the other side, and then with the other half of the group.

Guess where most of the group felt it?

If you guessed hamstrings, then you win the prize! The prize being the knowledge that you have good reading comprehension. There were a few people who felt it in their glutes, but most were in their hamstrings. This is similar to what I see when I get new clients who are runners (and with lots of non-runners).

I pointed out that the exercise I just had them do is not called a hamstring bridge; it’s called a glute bridge. And yes, it’s called a glute bridge because it’s an exercise for the glutes. Or at least by design, it’s an exercise for the glutes. In my experience as a trainer, however, it’s an exercise that works muscles other than the glutes for most people. Or at least that’s the case without coaching and regressions.

Let’s put this all together. We’ve got a group of runners, 90% of whom have hamstrings that feel tight, only 10% of whom have short hamstrings, and about 90% of whom feel hamstrings when performing glute bridges. Does anyone reading this think it makes sense that for most of these runners, performing proper glute bridges will do more to help their tight hamstrings than doing hamstring stretches?

That is my second example of why stretching is not always the answer to muscle tightness. If you haven’t yet read the part 1 post about stretching not always being the answer, you can read it here.

If you feel your glute bridges primarily in your hamstrings (or anywhere else other than your glutes), then give this post a read, where I go further into details about the glute bridge test, as well as cues we use to address this.

Q&A: Hamstring and glute exercises

Q&A: Glute and hamstring exercises

Q: I have some questions about glute and hamstring exercises. I find these hard groups to target. For example, I’ve read so many great things about deadlifts…but my problem is that I can’t hold enough weight to get a good workout – my hands give out.

A: There are a few options to consider.

1. If you have small hands, consider getting a women’s bar. Regular bars have a diameter of 28.5 mm, while a women’s bar has a diameter of 25 mm. That doesn’t sound like much, but I learned many years ago that it really is. I had a client who is a tremendous athlete and was always eager to “give ‘er” at the gym . Except with deadlifts. In fact she told me one day that she didn’t like deadlifts. I was floored. And I knew I had to right this wrong. After chatting for a few minutes, she mentioned that she was having a hard time holding the bar. She has small hands, as many people do – especially women.  That afternoon I ordered a Bella bar from Rogue. The day the new bar arrived, the client did her first set of deadlifts – with the new bar – and exclaimed: “I love deadlifts!” And all was right with the world again.

2. Another approach is to use an alternating grip (one hand faces your body; the other faces away from your body). With both hands facing the same way (usually palms facing the body), the bar will want to roll a bit, which makes it harder to hold.  Alternating grip addresses this, making it possible to lift more.

3: Alternating grip is probably the most widely used deadlift grip, although I’m not a fan because it puts uneven stress on your shoulders. I actually like straps for deadlifts. There are many out there who suggest you shouldn’t use straps because you should just work on your grip strength. Grip strength is important, and you should work on it. Deadlifts are an amazing exercise that work the biggest muscles in your body, so why would we let the little hand and wrist muscles be the limitation in how strong our glutes, hamstrings and back get? Use straps and find other ways to train your grip.

4. There are of lots of other great options for glutes and hamstrings:

  • Single leg versions of the Romanian deadlift are great – takes a bit of doing to get the balance, but because it’s one leg doing the work, you can get more involvement with the same amount of weight. These are typically done with dumbbells (one or two).You can also do cable machine versions of this.
  • For glutes there’s a great exercise called a shoulder elevated hip lift. You can do it on 2 legs, on one, and can progress to adding weight.
  • Stability ball leg curls are great for hamstrings. Or you can do a slideboard leg-curl to targets the glutes more than the hamstrings. If you don’t have a slideboard, there a couple of options: I have found that a krazy karpet works well – take your shoes off and do leg curls with socks only. Or you can pick up pieces of that material used under furniture to keep from scratching floors and put those under your shoes if you’re on hardwood.
