Questions this episode answers

How fast can I increase mileage when I start running again after having a baby?
Slowly. If you haven't run in about a year, start with a mile or two here and there and build without big spikes. The general rule I recall is about 10% more weekly volume at most.
Why do I have low back and groin pain when running after pregnancy?
Pregnancy pushes your pelvis into an anterior tilt, and that doesn't always reverse. The tilt robs the hip of range of motion and can feed groin, hip flexor and hamstring pain, even hip impingement.
What are the safest core exercises after pregnancy?
Isometrics, where you hold a position instead of moving. They work the abs, obliques, multifidus and pelvic floor at lower load, and they're used post-op. Lay a foundation of good intra-abdominal pressure first and keep breathing.
Is sucking my belly button to my spine good for diastasis recti?
It isn't the same as good intra-abdominal pressure. The transverse abdominis matters, but we need everything working together. Persistent diastasis can reflect poor pressure distribution.
How long should postpartum pain last?
For most people, pain from giving birth or a C-section should mostly fade by week six to eight. Pain that lingers past that may be an old knee or hip injury resurfacing under running load.

Your body can get back to running

A new mom wrote in. She gave birth 15 months ago. Now she gets a deep ache in her low back after even short runs, plus a sharp, pulling pain in her groin when she lengthens her stride or runs hills. She worried about pelvic floor dysfunction and diastasis recti.

First thing. You're entitled to feel like your body isn't the same. But I don't think your body can't get back to what it was. Plenty of mothers get fully back to what they want to do.

One side note. If you're running to lose weight, you don't have to. The abs are in the kitchen, the glutes are in the gym. If you run because you love running, let's get you back to it.

Build mileage like your tissues changed, because they did

The easy win is volume. Your brain remembers 10 milers. Your tendons and muscles have deloaded. It's not fair to hit them with volume they aren't prepared for.

I'm not a running coach. Basic logic still works. If you haven't run in about a year, start with a mile or two here and there. Build daily and weekly volume without big spikes. The general rule I recall is about 10% a week. Running 30 miles this week? Don't go past 33 next week.

Why the low back and groin hurt together

Pregnancy shifts your weight forward, so your pelvis tips into an anterior tilt (lumbar overextension). That helps while you carry a baby. Afterward it can reverse itself, but not always. People with old low back injuries show the same tilt.

That tilt robs the hip of function and range of motion. It can feed groin, hip flexor and hamstring problems, even hip impingement. I don't know this runner's exact diagnosis. It could be hip impingement, a hip flexor strain or a sports hernia. What stands out is the low back. Hip impingement doesn't usually start with back pain. When the back comes first, I think the back is a big part of it.

The pattern matters because it tells us which exercises to pick. Her pain flares with extension: running, hills and especially downhill. Anterior core work, glute work and rebuilding the hip hinge normally help.

Pelvic floor, diastasis recti and intra-abdominal pressure

Pregnancy is a bigger ordeal than most people realize. Your body changed for almost a year. A C-section is surgery, and I'd say it probably raises the odds of pelvic floor dysfunction, though not always. The longer a compensation lasts, the harder it is to break. Urinary issues, low back pain and hip and pelvis pain after birth are very common.

I lean on Janda's work on tonic and phasic muscles. Tonic muscles get overworked, tight and spasmy. The pelvic floor tends to go tonic.

The fix starts with intra-abdominal pressure working well. Most people sucked their belly button to their spine the first time. That isn't the same thing. The transverse abdominis matters, but we need everything working.

Diastasis recti is super common. When it persists, it can reflect poor pressure distribution. That ties into pelvic floor issues, low back pain, groin pain and overtonic muscles. Lay that pressure foundation first. Then progress to planks, side planks, glute bridges or banded bridges. You can do sit-ups till the cows come home. If the foundation isn't there, it won't change your problem.

Safe exercises and normal versus abnormal pain

The safest starting point is isometrics. You don't move, you hold. They can be hard, they load the abs, obliques, multifidus and pelvic floor, and they're given post-op. Breathe during them. Left alone, people default to Russian twists, boat pose and V-ups, and they move a lot even in hydrants. In rehab, don't let the spine move too much. When you run or pick something up, don't brace hard.

Timelines separate normal from abnormal. I'm on my fourth hamstring tear. Day two is always better. In a month I expect to jog. For most people, pain from birth or a C-section should dissipate by week six to eight. What lingers is often an old knee or hip condition resurfacing, from college running maybe, now that a changed body is under running load.

My checklist for her:

  • Is mileage appropriate for the buildup?
  • Are routes and paces mostly provoking ones? Try paces and cadences that don't hurt.
  • Do chosen exercises feel good? Squats may hurt while static split squats feel fine.
  • Are deadlifts back in the program?
  • Is there a past history now resurfacing?

Everything is a guess until someone examines you.

Key takeaways

  • Your body can get back to running after pregnancy, but build mileage slowly with no big spikes.
  • Anterior pelvic tilt after pregnancy can link low back pain to groin, hip flexor and hamstring pain.
  • Pain that flares with running and hills points toward anterior core work, glute work and the hip hinge.
  • Start pelvic floor and diastasis recti work with well-distributed intra-abdominal pressure, not sucking in your belly.
  • Isometric holds are the safest starting exercises; breathe through them.
  • Pain from birth should mostly fade by week six to eight; what lingers may be an old injury resurfacing.

You're listening to the Restoring Human Movement podcast, where movement experts discuss the latest evidence-based practices to help you and your clients move with mastery. Hey everyone, it's Sebastian, your co-host with the Restoring Human Movement podcast. Thanks for joining the show. If this is your first time, remember we do help people with lower quarter conditions, that's low back, hip, pelvis, sciatica, hamstrings, hip impingement, knees and so on. And this is usually for active audiences or active populations. We see people on telehealth as well, and we have consultations available. Now, I'm going to read an email today that we have from a postpartum mother runner.

So we will call this, we'll call the podcast Postpartum Runner Seeking Help, Looking for Lower Back Pain and Growing Pain to Return to Running. I think that's what we'll call it, but we may change that a little bit. So here's the email. My name is, we'll ditch the name, blank. I'm a new mom trying to get back into running. I've been listening to your podcast and find it incredibly helpful. However, I'm encountering some significant challenges with my lower back and groin pain. Since giving birth 15 months ago, I've noticed a persistent deep ache in my lower back, especially after even short runs.

This is coupled with sharp pulling pain in my groin, particularly when I try to increase my stride length or do any heel work. I'm concerned about potential pelvic floor dysfunction and diastasis recti. I'm struggling to balance my desire to run with the need to prioritize my postpartum recovery. I'd love to hear your insight on return to running, safe, sorry, a safe return to running strategy of postpartum runners. Exercises and strength training in the pelvic floor and core and how to differentiate between normal and abnormal postpartum discomforts and injuries. Thanks for, thanks for, thanks for, yeah, thanks for listening.

I can't even get, I get the rest of the email right, but I didn't get that one right, right. Anyways, so let's dive into a couple of these questions here. And first thing I want to say is if you are a postpartum mother, you don't need to feel like your body is not the same anymore. I mean, so I don't want to say you don't need to feel that way. You can feel that way. You're entitled to feel that way, but I don't think your body can't get back to what it was prior. There's plenty of mothers that, what do we call them? The lucky ones, you know, the ones that just get fully back and are able to do the things they want to do.

Other people just end up suffering. So I want to help you guys and give you some basic suggestions today of maybe some easy things that you could do if you're trying to get back into running. I think as a first and foremost is if you are trying to get back into running for the sake of any weight loss suggestions, just know the abs are in the kitchen, gluten are in the gym. So you don't necessarily have to run to lose any weight. Usually that's a nutritional part. But if you do like running for the sake of running, by all means, let's get you back to running. So the first thing that we can probably tackle to make sure that we're not losing some easy wins is making sure that you're building up your mileage appropriately.

Meaning if you haven't run in a long time, but you decided to go for 10 miles today, maybe that's not the best bet. I know a lot of people's brains can fathom the idea of going 10 miles again because you've been a runner in the past, but the rest of your body has changed its composure. So things tend to deload. Tendons and muscles have different abilities over that period of time. Not so you can't get them back. But it's not really fair for those tissues to be subjected to that amount of volume and load if they're not prepared for them either. So first and foremost, just make sure that you're building things up appropriately.

I am not a running coach, so a running coach would maybe have a better suggestion of that. But I think using some basic logic with it would make pretty good sense. If you haven't run in about a year or so, maybe consider going back and just doing a mile or two here and there. And then eventually build up your daily volume as well as your weekly volume without having any major spikes. I think that if I recall, the general rule is 10% or so. So if you're going to do 30 miles a week, maybe don't jump past 33 on next week for total volumes. So just make sure you're still obeying some of those basic principles.

The other thing in this email is about back pain and groin pain. And that's just that's something that's really common with some of our postpartum population. And it's not to say, again, that can't get better. It certainly can. But at least from even some of our non-pregnant populations or people who have been dealing with problems over the years with your lower back or pelvis. And now we are kind of in the scenario where we almost can say that our postpartum parents or our postpartum mothers kind of have an anterior tilt, but also people with past lower back injuries do as well. So that's something that they do have in common.

The reason why, obviously, mothers will have an anterior tilt is because they have a weight distribution that's forward now. And then later on, after you give birth, there may not be the need for the anterior tilt. Like the anterior tilt can help in the scenario of having weight on the front side of your body more so. But later, it can reverse engineer itself back. And so the anterior tilt scenario is very common with people with lower back and groin pain, which tend to sometimes create groin and hip flexor and hamstring issues. Even things like hip impingement can come from that. If you guys are interested in how that works, we do have a lot of YouTube videos on this topic, which covers how an anterior tilt, which is also the same thing as lumbar overextension, tend to rob the hip of some of its function and range of motion.

And that can account for some of the groin pain as well. So I don't know exactly what this person's condition is. It could be something like hip impingement. It could be something like a hip flexor strain. It could be even something like a sports hernia. I think the interesting part is that there's a lower back component. Hip impingement does not tend to have a lower back component. Now, you, especially in the beginning. Now, later on, we can say that the hip is not really functioning super well, and you may end up having a little bit of the workload go to your lower back. But a lot of times, if the low back precedes the groin condition, a lot of times I think the low back is a big part of it.

And if we're talking about the pattern that I can see, at least in this email, which developing patterns can be helpful because it helps us understand how to reverse engineer this in a rehab scenario and also pick which exercises to do. And so it seems like it's aggravated mainly with extension patterns. So it's going to be running, right? But also heel work, especially downhill running, can be an issue which exacerbates people with extension-based problems. Normally, a lot of anterior core work can help out. Some glute work can help out. But also rebuilding the hip hinge can help as well. Now, the other questions about potential pelvic floor dysfunction.

Yeah. I would say that people who have a C-section have probably a higher probability of having some pelvic floor dysfunction, but that's not always the case. Pregnancy is a bigger deal. I don't know if everybody realizes how much of an ordeal it can be. I mean, your body has changed over the course of almost a year. And even after giving birth, it's still not exactly the same. If you've had a C-section, that is the surgery, you know? And so there's a lot of things that can be compensations surrounding that. Obviously, pregnancy is a condition that doesn't last more than a year. But the longer the compensation, the harder it is to break out of that.

Old habits die hard, we say. And pelvic floor dysfunction, having urinary issues after the fact and having some lower back pain and even some hip and pelvis issues, like, is very common. And even people, after they've had abdominal surgeries without being pregnant, they sometimes have this as well. I would default back into the work of a lot of myrianda, which is about tonic and phasic group muscles. Tonic muscles, the ones that become overworked and have a tendency to becoming over tight and also spasmatic. And so usually the pelvic floor, the levator anise and so on that you've probably heard about can usually become a little bit more tonic.

And the way to solve this is first making sure that your intra-abdominal pressure is working well. If you have not been coached on that, it's important to have a realization of that because I think a lot of people that I've met who first have this problem, it's their first rodeo through it, they tend to suck their belly button to their spine, which isn't really the same thing. I know the transverse abdominis is important. That was a target for that particular tissue, but we need everything to work as well. Which also brings us to the question about diastasis recti. Dawne Costantino has put a few videos out about diastasis recti on YouTube.

So if you search performance place and diastasis recti, I think you'll come up with some of her videos. There's even a self-assessment for pelvic floor in there as well. And she shows a bunch of exercises which we can start people with for diastasis recti. But first off, having diastasis is common, super common. But also having it persist later can be a reflection of poor intra-abdominal pressure distribution, which goes long hand-in-hand with pelvic floor. It also goes hand-in-hand with low back pain and groin stuff and hip impingement and hip flexor strains and overtonic muscles. So all these are kind of colliding into a similar scenario.

So this is a very good email to encompass that. I would start first with making sure pelvic stability has a foundation of intra-abdominal pressure, which is well distributed. After that, you can make the exercises harder. You can make them into planks or side planks or glute bridges or banded bridges or whatever you want. We have the ones that we like that we share with our people when we do some of our telehealth sessions. They're very easy to coach. But I think understanding that there's a foundation that needs to be laid first is important because if you blow right through that, I mean, you can do sit-ups till the cows come home.

It's not going to change your problem, right? It's how you do it, which is important too. Now, the other questions of this email was return to safe running protocol. We discussed that a little bit before strengthening pelvic floor. I think as long as you understand there's intra-abdominal pressure first, and then you can choose whatever exercise you want. That is an important scenario. But also, if we had to choose exercises which are the safest, they're going to be non-movement ones or isometric loading exercises. Isometric loading, you can make them very hard. And they make it so there's a lot of abdominal contraction or the obliques or the multifidus or the pelvic floor, whatever you want.

But they're lower load and you hold them for a little bit longer. And they're the exercises where you're not moving. People are typically giving them post-op, so they're very safe to do. But you need to make sure you're breathing during them too. So, but I think give, when we give people the choice of exercise to pick, a lot of times they default to the ones that they've done in the past. Russian twist, boat pose, V-ups. And you can even see them with ones like hydrant exercise, which is supposed to be for the hip, like isolated hip movement with core stability. People move a lot. And so, just realizing that, not that your core can't move or your spine, your pelvis can't move.

It can. It certainly can. But if we're trying to condition it and you want to know what's safe in the beginning, isometrics are not letting it move too much, at least in your rehab scenario, is super important. But if you're bending over to pick something up or you're running, yeah, don't brace. Like, you can pick up stuff or run without having so much stiffness and attentiveness to your core. That would be ideal. Now, how to differentiate between normal postpartum discomfort and potential injuries. I tend to think that timelines are important with this. Now, if I, like, obviously I've never been, I've never been pregnant, but I have had other injuries.

Like, right now I have a hamstring tear that I had yesterday. I started yesterday. I've had three of them before. And so, I realized day two is always better. You know, within a week I'm not as much limping around, but I still can't really run. But over the course of about probably a month, I should be able to kind of start jogging around. Maybe not sprint, but I can push a sled. I can do squats. Like, there's normal things I should be able to do. And so, for you as well, like, once you've been cleared by your OBG, like, you're kind of, what is it, six weeks or so? It's kind of like you're able to, quote unquote, do anything.

But we know that you may not feel comfortable doing it or not everything feels good. But I think at least for most people's pain associated to giving birth or C-section and stuff like that, most of it should be dissipated at about week six, week eight or so. And then everything else may be remnant of some older, older injury, an old knee condition, an old hip one, the old hip one that resurfaced when you got pregnant. Or in this scenario, it's like maybe you had a hip condition back when you were in college running. And now it just, it's, it's post-pregnancy stuff. It's manifested itself. And so, not to say that you, pregnancy did it, but the lack of stability or the change of body over the course of that year, and now putting your body under some workload, such as running with good or bad buildup, is now getting it to manifest itself again.

And so, the only thing you can really do to predict future injury is to look at the person's past medical history. Like, I tore my hamstring four times now, right? Not even the same one. I would expect for it to happen again in my lifetime, but I don't expect for it to happen again immediately. Like, it should be years and years if risk factors and all the other parts are looked at. I would make sure that for this email listener, that we need to make sure that, number one, if their mileage is appropriate based upon what their buildup was again. Number two is, are they choosing trails or lengths that are provoking factors of them exclusively?

Like, we can try other types of paces and cadences that are not provoking just to get some mileage upon your body. Also, the exercises they're picking on their own, are they picking ones that feel good, or do they always hurt to do? Squatting may not feel good, but split stance or doing, like, non-moving lunges or split squats may be fine. Deadlifts should be incorporated back into the program if they're not already. So, the last thing is going to be make sure that they didn't have a past history of this that's all of a sudden now manifesting itself. So, there's a lot of ways that we can spin this, not to say I won't be, we don't cover it in our other videos and podcasts, we do.

But I think at least an overview on this is considering the variables. I don't want to say that giving exercises and suggestions can be helpful, they can, but everything is a guess. Literally, everything is a guess until you look at the individual and ask for their questions and examine them. I remember that I had a person recently that we were on a telehealth session, and so we had like five minutes left. They said, so what do you think I should do? Because there was a consultation. We don't usually give suggestions and consultations because we're just learning. And I said, I don't think you're going to want me to suggest anything.

They said, no, I suggest things. I said, would you rather me make a bad suggestion for the sake of making a suggestion that makes you feel worse, or do you just want me to make good suggestions? They said, well, you know, I'd rather make good suggestions. Well, then let me examine you. Let me talk to you a little bit more, and then let me actually coach the exercises. Don't just say do V-ups because that may make you feel worse, and I'm sure that's not what you want. So if you guys are looking for help, just reach out to us. We do love telehealth.
