Pelvic Floor Myths During Pregnancy That Can Make Symptoms Worse

When you find out you're expecting, it feels like the world suddenly becomes a "No-Fly Zone." Friends, family, and even random strangers at the grocery store start giving you advice. "Don't lift that!" "Don't get your heart rate too high!" "Are you sure you should be running?"
Most of this advice comes from a good place, but a lot of it is based on pelvic floor myths that just won't die. These misconceptions can actually make you feel more anxious and less prepared for birth. At The Health Lab in Carson City, we believe in holistic care—looking at your physical strength, your mental well-being, and your lifestyle to help you stay strong and confident.
If you have wondered is it safe to exercise during pregnancy, the evidence is reassuring. The American College of Obstetricians and Gynecologists recommends 150 minutes of moderate-intensity activity each week for most pregnant women, and links staying active to lower risk of gestational diabetes, preeclampsia, and cesarean birth. Far more risk comes from inactivity than from movement.
Let's bust some myths and get to the evidence-based truth.
Common Pelvic Floor and Exercise Myths
Myth 1: There Are "Unsafe" Exercises You Must Avoid
This is perhaps the biggest myth of all. People often look for a list of "forbidden" moves. Here is the truth: There are no universally unsafe exercises during pregnancy. There are only exercises that your body might not be ready for at this moment. Your body is incredibly resilient. Instead of following a list of "don'ts," we look at how your body handles the load. If you were a weightlifter before pregnancy, you don't have to stop just because there's a "baby on board."
Myth 2: Exercise Can Lead to Miscarriage
For a healthy pregnancy, there is no evidence that moderate-to-vigorous exercise causes miscarriage. In fact, staying active is one of the best things you can do for your pelvic floor and your mental health. It improves circulation, boosts your mood, and prepares your muscles for the "marathon" of labor.
Myth 3: You Have to Keep Your Heart Rate Low
You might have heard that you shouldn't let your heart rate get too high. This is outdated advice! You don't need to panic if you're breathing hard. High-intensity exercise—even the kind where you are working too hard to carry on a full conversation—is still considered safe for pregnant women who are accustomed to that level of activity. Your body is great at telling you when to slow down.
The outdated 140-beats-per-minute ceiling was dropped from clinical guidance decades ago. Current ACOG guidance uses rate of perceived exertion, not a fixed heart-rate cap.
The Facts About Lifting, Running, and Moving
You might be wondering about the specifics of your workout. Let's clear the air:
Can I lift weights? Yes! Strength training is highly recommended. It helps your body support the extra weight of pregnancy and helps prevent back pain.
Can I run? Yes! If you were a runner before, you can usually keep running throughout your whole pregnancy as long as it feels good.
Should I avoid lying on my back? While some people feel dizzy on their backs in the third trimester (due to the weight of the baby on a major vein), it isn't a strict "never." If you feel fine, floor or bench exercises are okay.
Runners managing leaking or pelvic heaviness can find specific strategies in our guide to pelvic floor therapy for runners.
What about Coning and Diastasis Recti?
You might see your stomach "cone" or "dome" during a core exercise. This is related to Diastasis Recti—the separation of the abdominal muscles.
Important Fact: Diastasis Recti happens in almost 100% of pregnancies by the third trimester. It is a normal adaptation to make room for a human being!
Coning is just a sign that your pressure management isn't quite right. It's not "damaging" you, but it is a signal to modify the move or check in with a pelvic floor therapist to learn better breathing techniques.
Roughly 60% of women still have some degree of separation at six weeks postpartum, which is why pressure management matters more than avoidance. We cover the full picture in our deep dive on diastasis recti, and the breathing mechanics behind it in how your diaphragm and pelvic floor work together.
How to Know When to Modify
The goal is to hit about 150 minutes of exercise per week, which should include strength training. But how do you know if you're overdoing it? Listen to your body rather than a rulebook. You should consider modifying your workout if you experience:
Leaking urine or "heaviness" in the pelvic area.
Pain in the pubic bone or lower back.
Stop Immediately and Call Your Doctor If:
While exercise is safe, these are the "red flags" that mean you need medical attention:
Excessive shortness of breath before or during exertion.
Severe chest pain or heart palpitations.
Regular and painful uterine contractions.
Persistent dizziness or faintness.
Persistent loss of fluid from the vagina.
The Big Picture
Your mindset matters just as much as your muscles. If you are afraid to move, your muscles can get tight and stressed, which actually makes pelvic floor symptoms worse.
At The Health Lab, we want you to feel empowered, not restricted. You aren't fragile; you are growing a person! By following evidence-based guidelines and ignoring the myths, you can stay strong, active, and confident all the way to graduation day.

Frequently Asked Questions About Exercise During Pregnancy
Is it safe to exercise during pregnancy?
For most healthy pregnancies, yes. ACOG recommends 150 minutes of moderate activity per week and links regular exercise to lower rates of gestational diabetes and preeclampsia. Anyone with placenta previa, preeclampsia, or certain heart and lung conditions should clear activity with their provider first.
What exercises should you avoid during pregnancy?
No exercise is universally banned. Contact sports, activities with a high fall risk such as downhill skiing, and scuba diving carry real hazards and are worth avoiding. Beyond those, the better question is which movements your body handles well today, not which appear on a forbidden list.
Can you lift weights while pregnant?
Yes. Strength training helps support added weight and reduces back pain. The shift is in pressure management and breathing, not in dropping the barbell. Coning during a lift signals a need to modify, not stop entirely.
Are pelvic floor exercises during pregnancy worth doing?
Pelvic floor exercises during pregnancy support continence and prepare the muscles for labor, but coordination matters more than constant squeezing. A pelvic floor physical therapist can assess whether yours need strengthening, relaxation, or better timing with the breath.
When should I stop exercising and call my doctor?
Stop and seek care for vaginal bleeding, regular painful contractions, fluid leaking from the vagina, chest pain, severe shortness of breath, or persistent dizziness. These signs warrant medical attention regardless of how far along you are.
