Pilates is a proven training method that helps many pregnant women stabilize their core and prevent discomfort. Nevertheless, there are specific exercises that should not be performed during pregnancy to avoid unnecessarily straining both mother and child. In the following, we will explain which Pilates exercises are contraindicated, why this is the case, and what alternatives are available.
Pilates during Pregnancy – Fundamentals and Benefits
Pregnancy is a time of intense physical changes. The growing belly, altered joint conditions, and a shifted center of gravity present new challenges for the body. Regular, adapted Pilates can help strengthen the muscles during this phase – especially the pelvic floor, deep abdominal, and back muscles. In addition to improving posture, Pilates also supports breathing, promotes relaxation, and can thus increase general well-being.
It is essential that the training is individually adapted to the needs of the expectant mother. Expert trainers modify the exercises according to the trimester and ensure that no excessive strain occurs.
Dangerous Pilates Exercises during Pregnancy
Not every exercise that is useful in regular Pilates training can be safely integrated into pregnancy. We advise against the following exercises:
1. Prone Exercises
As the abdominal circumference increases, lying on the stomach is not only uncomfortable but can also impair blood flow. Especially in the second and third trimesters of pregnancy, prone training is discouraged. Exercises that excessively push the spine into a hollow-back position should also be avoided, as they increase pressure on internal organs and the diaphragm.
2. Intensive Abdominal Muscle Exercises
The rectus abdominis muscles should no longer be intensely trained after the 20th week of pregnancy to avoid diastasis recti – a separation of the straight abdominal muscles. Exercises like classic sit-ups or crunches, which place massive strain on the abdomen, are contraindicated during this time. Instead, the focus should be on gentle core stabilization.

3. Exercises with Strong Rotational Movements
Dynamic and rapid rotational movements can excessively strain the spine and pelvic floor. Especially with exercises that require strong upper body rotation, there is a risk of muscular imbalances due to asymmetrical loads. Caution is advised here, as uncontrolled rotation can further destabilize the already changed body.
4. Supine Exercises
In the advanced stages of pregnancy, prolonged lying on the back should be avoided. The pressure of the growing uterus on the inferior vena cava can lead to circulatory problems and thus impair the supply to mother and child. Therefore, Pilates exercises performed in a supine position are modified or entirely avoided in later trimesters.
5. Exercises with High Impact and Jumping Components
Even if jumps and jarring movements are rather rare in classical Pilates, the rule is: Any exercise that excessively strains the body or requires sudden, explosive movements should be avoided during pregnancy. An abrupt change from tension to relaxation can increase the risk of injury and lead to unwanted pressure on the pelvic floor and joints.
Recommended Alternatives and Safe Modifications
Instead of risky exercises, we rely on modified variants during pregnancy that meet the changed needs. The following approaches have proven particularly beneficial:

Gentle Stabilization Exercises
Exercises in quadruped position, on the side, or sitting offer an excellent alternative. These positions relieve the abdomen but still allow for effective training of the deep core muscles. Slow, controlled movements improve stability without exerting excessive pressure on the abdomen.
Focus on the Pelvic Floor
A strong and flexible pelvic floor is essential not only for daily life but also for the upcoming birth. We integrate targeted pelvic floor exercises into the training, practicing conscious tension and relaxation. These exercises, combined with gentle breathing techniques, can lead to improved body awareness.
Breathing and Relaxation Exercises
The deep breathing exercises embedded in Pilates play a central role in pregnancy. Conscious diaphragmatic breathing expands the rib cage, which improves oxygen supply and reduces stress. These elements can be easily integrated into any training session and contribute significantly to relaxation.
Modified Core Exercises
Instead of intensive abdominal muscle exercises, we recommend variations in which the abdominal muscles are activated in a neutral position. For example, exercises can be performed sitting or in slightly elevated torso positions, with the focus on gentle activation rather than strong contraction.
Tips for Safe Pilates Practice During Pregnancy
To minimize the risk of injury and maximize the benefits of training, we recommend the following rules:
-
Consult your doctor: Before starting or continuing a Pilates program, always consult your treating physician. This is essential, especially in cases of high-risk pregnancies or pre-existing conditions.
-
Individual adaptation: Every pregnancy is different. Therefore, training should be individually adapted to the physical conditions and the respective trimester.
-
Listen to your body: Any signal from the body – be it discomfort, pain, or dizziness – should be taken seriously. In such moments, stop the exercise immediately and adjust the training if necessary.
-
Qualified guidance: Ideally, training takes place in a Pilates class specifically designed for pregnant women, where trainers have experience dealing with the physical changes during pregnancy.
-
Appropriate equipment: A non-slip mat, comfortable sportswear, and possibly aids such as small cushions or exercise balls support the safe execution of exercises.
-
Slow progression: Increase the intensity of your training very cautiously. The focus is on continuous, gentle improvement of stability and flexibility, not on rapid progress or intense exertion.

Frequently Asked Questions (FAQ)
Can I do Pilates during pregnancy?
Yes, generally Pilates is possible during pregnancy and can have many positive effects. It is important that the exercises are adapted to the individual's condition and the respective trimester. In case of doubt, medical advice should always be sought.
Which Pilates exercises should definitely be avoided?
Specifically, prone exercises, intensive abdominal muscle exercises (e.g., classic sit-ups and crunches), strong rotational movements, and prolonged supine training are not recommended. These can excessively strain the abdomen, restrict blood flow, and increase the risk of diastasis recti.
Are there safe alternatives to the contraindicated exercises?
Yes. Exercises in quadruped position, side-lying, or sitting offer safe alternatives. Targeted pelvic floor training and modified core exercises that activate the abdomen in a neutral position are also recommended.
How can I tell if an exercise is too intense?
Pay attention to your body's signals. Pain, dizziness, or an uncomfortable feeling during the exercise are warning signs. In addition, expert guidance in a special prenatal Pilates class is helpful to ensure correct execution.
Do I have to completely forgo Pilates in a high-risk pregnancy?
In high-risk pregnancies or specific complications (such as premature contractions, vaginal bleeding, or cardiovascular diseases), it may be necessary to adjust the training or forgo it entirely. The individual situation should always be evaluated in consultation with a doctor.
Conclusion
We are convinced that Pilates – in an adapted, safe version – offers an excellent opportunity to strengthen the body, prevent discomfort, and mentally prepare for childbirth even during pregnancy. It is crucial to pay close attention to one's own limits and consistently avoid exercises that place excessive strain on the abdomen and back. With expert guidance and individually tailored modifications, expectant mothers can fully enjoy the benefits of Pilates training.
We recommend seeking comprehensive information, consulting experts, and always listening to your own body before training. This way, Pilates training remains a valuable building block for health and well-being – both during pregnancy and in the period thereafter.
