Bench Press While Pregnant: How to Modify Each Trimester

Table of Contents

All trimester recommendations are general guidelines that we have found to work well for our prenatal clients. As a disclaimer, these guidelines should not be considered the set-in-stone standard for every pregnant woman as every pregnancy is unique.  Our recommendation is to adjust how you bench press while pregnant based on how you feel each day. 

Pregnancy is a state of growth, both in body and mind. Allow this time to be an opportunity to explore new movements without competition or performance expectations.

Bench Press in the 1st Trimester

The horizontal press, or the bench press, can be modified to meet the demands of pregnancy based on each individual mother. During the first trimester, as with most lifts, the bench press will probably look fairly similar to pre-pregnancy. The biggest adjustments will be loading. All lifts should decrease to the 70% 1RM loading, focusing on muscular endurance with 2-4 sets at 8-12 repetitions. We like to pair the bench press with a core stability movement, such as the pallof press or farmer carries. Remember that you always have the option to explore with loading options; barbell, dumbbells, kettlebells, etc.

During this trimester, it will be important to fully incorporate the ninja roll into all movements on and off the bench or floor for the horizontal press. This movement should be how you get up and down onto your back, regardless of location; this includes when you get up out of bed in the morning!

As this trimester progresses, the additional curvature of the lumbar spine and additional weight of the belly may result in discomfort in the hips/back when the feet are on the floor during the bench press. We recommend adjusting to an elevated feet position or feet on the bench. Feet on the bench may feel a little less stable, so be prepared for that sensation and ensure you are in the middle of the bench. Option to also elevated the feet (in the video below), but this will be the most unstable of the options.

Bench Press in the 3rd Trimester

As the third trimester approaches, the desire to lay flat on the back may not be as comfortable.  If laying flat on your flat is still comfortable, feel free to continue to bench press on your back.

Symptoms to watch for when exercising on your back:

  • Dizziness
  • Seeing Spots
  • Lightheadedness

 

If you experience any of those symptoms, put the weight away, and roll to your left side to rest until you feel more recovered.  Then we should transition to more upright or inclined positions.

We tend to progress towards the inclined dumbbell bench press during the later portion of this trimester. We prefer dumbbells over barbells in the incline press, as it’s easier to get in and out of, and the movement is significantly less awkward with dumbbells.

The inclined position allows the mother to decrease the distance that she needs to lean back, thus preventing or limiting any abdominal coning, and the inclined position tends to be more comfortable as the lumbar spine becomes more curved in the later portions of pregnancy.

The modifications per trimester are not set in stone and can fluctuate between mothers and pregnancies. Some mothers prefer the incline bench press starting the first trimester, and other will bench press their entire pregnancy. Pregnancy is a state of growth, and an opportunity to explore movement that best suits your body each day.

Pay attention to how the movement feels for your body, not necessarily how hard the movement is. Do you feel pulling or strain in your abdomen or back? Is the position comfortable to be in? Do you feel confident in the lift? Use this opportunity to really sync up with your body and actually listen to what it is telling you.

Frequently Asked Questions

What exercises should be avoided while pregnant?
There's really not much that is truly "unsafe" for prenatal workouts! Low to high intensity levels are generally fine, you can twist and rotate, and you can even do supine exercises on your back. The one thing we'd skip is deep compression-type twists, mostly because they just aren't comfortable on a pregnant belly. The key is to pay attention to the messages from your body and adjust your workouts based on how you feel each day. We bust the most common fears in our prenatal workout myths guide.
Is it okay to lift heavy weights while pregnant?
You can keep lifting, but we recommend bringing your loads down to about 70% of your 1RM. Focus on muscular endurance, with 2–4 sets of 8–12 reps. Pay attention to how the lift feels for your body, not just how hard it is. If you feel pulling or strain in your abdomen or back, or you don't feel confident in the lift, it's a sign to adjust.
Can I do squats 7 weeks pregnant?
Yes! At 7 weeks you're in the first trimester, when the belly usually isn't a factor yet, so squatting can look fairly similar to pre-pregnancy. The main adjustment is loading: drop to about 70% of your 1RM and focus on 2–4 sets of 8–12 reps. We like to pair each squat set with a stability exercise, such as step-ups or single-leg bridges. See our full squat modifications for pregnancy for each trimester.
Can you build muscle while pregnant?
Yes! To build muscle density and size, you need to put more stress on the muscle over time than it's used to handling, which means moderate to hard workouts with an external load. Lifting also makes your muscles, tissues, and bones denser and more resilient, which can enhance your healing postpartum. Learn more about the benefits of weightlifting during pregnancy.
Can I do planks while pregnant?
You can, but watch for coning! A full plank may be too challenging as your belly grows. Adjusting to an incline (an elevated plank) or bringing your knees under your hips into a bear position can better support your core. The more you minimize coning under exertion, the safer your core will be. Here are more ways to prevent coning during prenatal workouts.
