Maintaining a fitness regimen during pregnancy is often a delicate balancing act between pushing the body to stay strong and honoring the profound physiological changes that occur during gestation. For Jesica Cirio, the Argentine model and presenter, this balance is a visible part of her journey as she prepares for the arrival of her second child. Through a series of recent updates on her Instagram stories, Cirio has provided a window into her current training philosophy: a focused, strength-based approach designed to support her body through the physical demands of a second pregnancy.
As a board-certified physician, I have seen how the shift in a woman’s center of gravity—caused by the growing uterus and changes in breast tissue—can lead to chronic lower back pain and postural instability. Strength training, when performed under professional supervision, is not merely about aesthetics; it is a clinical tool for mitigating these common pregnancy complications. Cirio’s routine, executed alongside her personal trainer, emphasizes functional strength that targets the exact muscle groups most prone to strain during this period.
The routine shared by Cirio is not a generic “pregnancy workout” but a structured strength circuit. By focusing on resistance training for both the upper and lower body, she is addressing the necessity of muscular endurance and joint stability. This approach aligns with modern obstetric guidelines that encourage active pregnancies for those without medical contraindications, noting that controlled exercise can improve mood, regulate glucose levels, and potentially ease the recovery process postpartum.
Targeting the Posterior Chain: Support for the Shifting Spine
A significant portion of Cirio’s routine is dedicated to the upper body, specifically the back. What we have is a strategic choice. During pregnancy, the shoulders tend to roll forward and the lumbar spine increases its curve (lordosis) to compensate for the weight of the belly. Strengthening the posterior chain is essential to counteract this “slumping” effect.
One of the primary movements Cirio utilizes is the Lat Pulldown (tirón al pecho). By pulling the weight down toward the chest, she engages the latissimus dorsi—the largest muscle of the upper body. From a medical perspective, this exercise helps stabilize the shoulder girdle and promotes a more upright posture. The movement activates the biceps, trapezius, and rhomboids, which are critical for pulling the scapulae together and reducing the tension often felt between the shoulder blades.
Complementing the vertical pull of the lat pulldown is the Machine Row (remo en máquina). While the pulldown focuses on width and vertical stability, the row provides horizontal pull, which builds thickness and density in the mid-back. This exercise targets the middle and lower trapezius and the rhomboids. For an expectant mother, this means a stronger “anchor” for the torso, which helps in maintaining spinal alignment as the pregnancy progresses into the third trimester.
Lower Body Stability and Core Integration
While the upper body provides the structural support, the lower body provides the foundation. Cirio’s routine transitions from the back to the legs, focusing on isolation and compound movements that protect the joints while building power.
The Quad Extension machine is used as an isolation movement for the quadriceps. Strengthening the anterior thigh is vital for knee stability. As weight gain increases during pregnancy, the load on the knee joints rises significantly. By isolating the quads, Cirio is ensuring that her knees have the muscular support necessary to prevent strain and maintain mobility during daily activities.
The most demanding element of her circuit is the Bulgarian Split Squat with dumbbells. This exercise is a gold standard for lower-body development because it requires unilateral strength—meaning each leg must work independently. This movement intensely activates the glutes, quadriceps, and hamstrings. More importantly, because it requires significant balance, it forces the core to engage deeply to maintain stability. While traditional abdominal crunches are often discouraged in later pregnancy due to the risk of diastasis recti, the stabilization required for a split squat provides a safe, functional way to maintain core tension.
Summary of Jesica Cirio’s Pregnancy Strength Circuit
| Exercise | Primary Muscle Target | Pregnancy-Specific Benefit |
|---|---|---|
| Lat Pulldown | Latissimus Dorsi / Upper Back | Improves posture; reduces shoulder tension. |
| Machine Row | Rhomboids / Mid-Back | Supports spinal alignment; prevents slumping. |
| Quad Extension | Quadriceps | Increases knee stability and joint support. |
| Bulgarian Split Squat | Glutes / Quads / Core | Builds lower-body power and functional balance. |
The Clinical Importance of Supervised Training
Cirio performs these exercises under the guidance of a personal trainer. This is the most critical component of her routine. Pregnancy is not a static state; it is a dynamic physiological evolution. An exercise that is safe in the first trimester may need modification in the second or third due to changes in ligament laxity—caused by the hormone relaxin—which can make joints more prone to injury.
For any woman looking to emulate this routine, the “talk test” is a useful clinical marker: Consider be able to carry on a conversation while exercising. If you are too breathless to speak, the intensity is too high for the gestational stage. The focus should always be on controlled eccentric movements (the lowering phase of the exercise) rather than explosive power, to avoid sudden spikes in blood pressure or joint strain.
Beyond the physical, the emotional benefits of maintaining a routine are substantial. Strength training releases endorphins that can combat the anxiety and mood swings associated with hormonal shifts. By staying active, Cirio is not only preparing her body for the physical act of labor and delivery but is also prioritizing her mental well-being.

As Jesica Cirio continues her pregnancy, her commitment to a structured, professional fitness plan serves as a practical example of how to integrate health and motherhood. The next milestone for the model will be the further adaptation of her routine as she enters the final stages of her pregnancy, where the focus typically shifts from muscle hypertrophy to pelvic floor health and mobility.
