You’re in the right place!
After reading this post, you are going to learn:
- Specific exercises you should avoid during each trimester of your pregnancy,
- The activities you should not participate in during pregnancy, and
- Other contraindications to exercise in pregnancy.
Let’s get started

Ok, moving on.
What activities should be avoided during pregnancy?
During pregnancy it is important to avoid any sort of activity that can cause or increase the risk of:
- direct abdominal trauma
- falling, and
- severe dehydration.
1. Contact sports
Contact sports include activities like basketball, football, volleyball, and soccer. These activities greatly increase the risk of trauma to your abdomen, falling, and endangering your pregnancy.
2. Outdoor Cycling
Outdoor cycling is another physical activity that is not recommend during your pregnancy. There are too many risks including falling off your bike, crashing into another biker or pedestrian, and/or getting hit by a car. If you really love biking I would recommend a stationary bike.
3. Scuba diving
Scuba diving is another activity that poses far too many risks in pregnancy. During the second and third trimester, your blood pressure normally decreases due to the changes occurring in your body.
Scuba diving affects your cardiovascular system by causing your blood vessels to constrict. This leads to your blood pressure increasing, while decreasing the actual volume of blood your heart pumps out to your tissues and organs.
As a result, this can compromise blood flow to your baby.
In addition, carbon dioxide can builds up in your body as you are not effectively ventilating. High levels of carbon dioxide can poison you and your baby.
Lastly you increase the risk of developing an embolism or blood clot that could be fatal.
4. Roller blading
Roller blading is a fun activity but one that needs to be avoided during pregnancy. This is obviously due to the risk of falling and injuring yourself or your baby.
Save the ski boots for next year. Downhill skiing is a high risk sport and definitely should be avoided while you are pregnant for all the same reasons as above.
6. Hot Yoga
Aside from the activities above, it is also important to avoid extreme temperatures.
Hot yoga is one of the activities you should avoid due to the very high temperature associated with the practice. What you may not know is, hot yoga can cause very dangerous levels of dehydration which can compromise blood flow to your baby, and even lead to preterm contractions. It is very common for pregnant women to become dehydrated and it is a common reason why women come to labor and delivery triage for evaluation.
7. Hot Pilates
Hot Pilates should be avoided during your pregnancy for the same reason hot yoga should be avoided.
What Specific Exercises Should You Avoid in Pregnancy?
During pregnancy it is very important to avoid any exercise that requires you to be flat on your back or flat on your stomach.
Let me explain why.
Your uterus is positioned anterior, or in front of, your major blood vessels.
These blood vessels include the aorta which carries oxygenated blood from your heart to the rest of your body and the inferior vena cava which carries deoxygenated blood from your body back to your heart.
When you lay down flat on your back, your gravid uterus will compress these vessels impeding the flow of blood, decreasing the oxygen being delivered to the rest of your body.
This can cause symptoms such as feeling faint, shortness of breath, and fatigue. Plus, you will compromise blood flow to the uterus as well.
Lying flat on your stomach should be avoided for obvious reasons.
You have a growing baby and placenta inside your uterus. If you lie down flat on your stomach, you will put a lot of pressure on the amniotic sac which in theory can compress the placenta and umbilical cord, inhibiting the flow of vital nutrients, blood, and oxygen to your baby.
Not to mention, this will be very uncomfortable for you as well.
So please do not lie on your back or your stomach while pregnant.
Here are common examples of exercises you should avoid.
Sit-ups & Crunches
Sit ups require you to be flat on your back and place too much pressure on your core muscles.
Crunches are just a a partial version of the sit-up. They should be avoided for the same reason.
Instead You Can Do:
Modified planks. Check out my post on planking while pregnant to learn more.
Squatting is great for pregnancy. I have an entire post on how to squat safely.
With that said, you should avoid heavy squats because it requires very strong levels of intra-abdominal pressure.
It’s hard to say how much exertion is safe to do while pregnant, but you certainly don’t want to be lifting very heavy weights. The American Medical Association recommends that you don’t lift anything greater than 50 lbs after the third trimester.
In addition, heavy barbell exercises may have an increased risk of injury during pregnancy as your muscles and joints have increased laxity which may be due to a hormone known as relaxin.
Instead You Can Do:
Heavy deadlifts should be avoided for the same reasons as heavy squats.
Instead You Can Do:
Light romanian deadlifts or dumbbell sumo deadlifts which I cover in my 2nd trimester strength workout.
Bench press requires you to be flat on your back, and has a risk of you potentially dropping the weight on your abdomen.
Instead You Can Do:
Modified push-ups. Check out my post on pregnancy push-up variations to learn more.
Glute bridges again require you to be flat on your back for prolonged periods of time.
Instead You Can Do:
Hip thrusts with your back supported against a bench or a chair.
Now in this next section I am going to explain which exercises should be avoided during each trimester of pregnancy.
Let’s get started.
Exercises to avoid during the first trimester of pregnancy
In the first trimester of pregnancy there are not too many exercises you need to avoid as most women don’t even know they are pregnant and your uterus is extremely small as the fetus is very small.
With that said, it is best to avoid the major activities that increase your risk of abdominal trauma, and extreme elevations in your heart rate or body temperature.
- contact sports
- hot yoga, and
- high intensity interval training
Exercises to avoid during the second trimester
During the second trimester your uterus undergoes rapid growth as does your baby.
It is best to avoid any exercise that increases your risk of direct abdominal trauma as well as exercises that require you to be flat on your back or flat on your stomach.
- contact sports
- jumping/plyometric activities
- hot yoga, and
- all exercises where you are on your back or stomach
Are There Household activities to avoid during pregnancy?
There aren’t any specific household activities you should avoid during pregnancy.
You must listen to your body and avoid anything that causes pain or discomfort.
Other Related Questions
What are the risks of exercising while pregnant?
The major risks of exercising while pregnancy include: increased risks of maternal trauma, and increased risk of a temporary decrease in blood flow to your uterus.
The good news is, if you are careful and exercise using a mild to moderate intensity, these risks are minimal.
In addition, many women report the development of low back in pregnancy. If done incorrectly, exercise can worsen or exacerbate low back pain.
When should you stop or slow down?
If you have medical clearance from your healthcare provider, and you have no contraindication to exercise, there is no need for you to stop exercising at a specific time period.
However, you may notice that in the 3rd trimester, exercise will become more difficult. You will experience less mobility, increased shortness of breath, and increased fatigue.
It is appropriate to slow down in the second and third trimesters.
Always listen to your body!
Your body is amazing at non-verbal communication. If something doesn’t feel right, don’t do it.
Now, if you have never exercised prior to pregnancy, make sure to speak with your doctor to ensure you are cleared to exercise.
What women should not exercise?
Medical contraindications to exercise during pregnancy include:
- Significant lung disease
- Significant cardiac disease
- Multiple gestations including twins or triplets
- Cervical insufficiency
- Preterm labor
- Severe anemia
- Vaginal bleeding
- Threatened Abortion
Can exercise cause a miscarriage?
There have been no studies linking exercise and miscarriage risk.
With that said, it is important to speak with your doctor regarding your individual scenario.
In which month should I start exercise during pregnancy?
You can start exercising as soon as you find out you are pregnant as long as you don’t have any contraindications to exercise as mentioned above.
