Is Working Out Safe in the First Trimester?

Exercise during early pregnancy is completely safe for most people. But you will want to follow all the dos and don’ts listed below. If you are concerned about the 2 week wait (2ww) or waiting on a beta test, read this pre-pregnancy and infertility advice on exercising during the two week wait and early pregnancy.

Ultimately, the most common concern amongst pregnant women is whether exercising will induce a miscarriage. Exercise actually soothes many of the aches and annoyances of the first trimester, and continuing to exercise throughout the pregnancy can only add benefits to the mother and her baby.[1] According to ACOG, women with uncomplicated pregnancies should be encouraged to engage in aerobic and strength-conditioning exercises before, during, and after pregnancy (ACOG CO 804).

Because there are certain conditions that put you and your baby at risk, get your doctor’s permission before beginning any exercise routine. Please stop exercising and seek medical attention if any of the following occur: vaginal bleeding, regular painful contractions, amniotic fluid leakage, difficulty breathing before starting exercise, dizziness, headache, chest pain, muscle weakness, and calf pain or swelling.

First Trimester Exercise: What You Need to Know

Before you move forward with exercise, we need to discuss some of the basics of exercising during pregnancy. If pregnancy hasn’t taught your already, overall, your body is incredibly smart! As it grows a tiny human being, it adjusts your blood pressure, expands your rib cage, and increases your blood volume, among many other amazing things … all without you telling it to do so.

Exercise during first trimester tends to be challenging. The volume of blood pumped out by the heart each minute increases by 5 – 6 weeks gestation. This major change can cause symptoms such as dizziness, rapid heart rate, and the feeling of not being able to take a deep breath. This can make you feel low on energy, green to the gills, tired, and simply blah. HOWEVER, if you can manage it, you will probably feel more energized from working out than if you skip it.

Check out the our Prenatal and Postnatal Exercise Guide for a comprehensive list of the dos and don’ts during pregnancy exercise. But, keep in mind, these adaptations are unique for every pregnant woman and not every woman will respond to exercise during pregnancy in the same way. So listen to your body! It will tell you what’s too much and when you should take it easy.

First Trimester Workouts

The Moms Into Fitness prenatal exercise program is divided into trimesters AND into basic level or intermediate/advanced level. The workouts are designed to work with your body during the different phases on your pregnancy. You’ll feel better knowing you’re doing what’s safe and effective for your body at any given stage — but obviously, your body knows best, so listen to it and adapt what doesn’t feel right for you.

In our first trimester workouts, we focus on functional training in minimal time. We keep the workouts shorter since most of us are low on energy in this trimester. Try these workouts early in your pregnancy:

For the basic level, you’ll have 21 different videos for first trimester alone (the intermediate/advanced level has 30!) plus more videos as you get into your second and third trimesters. We mix it up with strength, cardio, barre, yoga, HIIT — you won’t get bored doing the same thing over and over, I promise.

I would love to help you nurture yourself and build confidence through fitness, nutrition, and community. No pressure, no stress, and no experience necessary.
