The lymphatic system is the body's drainage system, removing excess fluid from tissues and returning it to the bloodstream. It works closely with both the circulatory and immune systems. The circulatory system delivers oxygen and nutrients to tissues while removing waste through tiny blood vessels called capillaries. However, not all fluid is reabsorbed—about 15% is left behind in tissues. The lymphatic system collects this leftover fluid, called lymph, and returns it to the bloodstream via a network of open-ended vessels. Additionally, the lymphatic system supports immune function by transporting lymph, which contains white blood cells that help fight infection. Unlike the circulatory system, the lymphatic system doesn’t have a central pump, like the heart, to move lymph.
The lymphatic system includes the thymus, bone marrow, spleen, and lymphoid nodules and lacks a central pump like the heart. Instead, it relies on body movement and muscle contractions to function—making core engagement in exercises like Pilates crucial. When you engage your core muscles—particularly the deeper ones like the transverse abdominis—you create pressure within the abdominal cavity.
Why is this important for lymphatic drainage? Core muscles are closely tied to diaphragmatic and respiratory movements. By activating your core, you create a 'pump-like' effect that assists both lymphatic and venous blood flow in moving upward toward the heart. This process increases intra-abdominal pressure, stimulates the diaphragm, and engages surrounding muscles. The compression and release cycle pushes fluid through veins and lymphatic vessels (with one-way valves), aiding circulation and improving lymphatic drainage. It’s a natural way to support the body’s flow without relying on gravity alone!
"As the spring freshness born of the heavy rains and vast masses of melting snows on mountains in the hinterlands cause rivers to swell and rush turbulently onward to the sea, so too will your blood flow with renewed vigor as the direct result of your faithfully performing the Contrology exercises." Joseph Pilates

Core Engagement and the Lymphatic System
When Pilates instructors ask you to "engage your core," they’re not just talking about stabilizing your torso—they’re also encouraging you to activate a deep layer of muscles, particularly the transverse abdominis. When activated, the transverse abdominis acts as a stabilizer for your spine and pelvis, but more importantly, it also creates internal pressure within the abdominal cavity.
This pressure can help facilitate lymphatic drainage in the following ways:
Pressure Creation: Engaging your core increases the intra-abdominal pressure, creating a “pump” that helps move lymph fluid through the abdominal region. The lymphatic system relies on body movements, muscle contractions, and shifts in pressure to circulate lymph. Without this muscle engagement, lymph can become stagnant, especially in areas with fewer lymph vessels, like the abdomen.
Movement of Lymph Fluid: The abdominal cavity contains key lymph nodes that are responsible for filtering waste and toxins from the lymph. When you engage the core muscles, you're helping to push lymph fluid toward these nodes and further through the lymphatic network.
Breathing and the Core: Deep breathing, which is integral to Pilates, is another powerful tool for promoting lymphatic drainage. As you breathe in deeply, the diaphragm pushes down, creating a sort of “massaging” effect on the organs, which helps push lymph toward the lymph nodes. When you engage the core at the same time, you amplify this effect, supporting the movement of lymph throughout the body.
Why Core Engagement Matters More Than Just Lymph Nodes
Many people are familiar with the common lymphatic drainage points, such as the groin, behind the knees, and the neck. These are areas where lymph nodes are concentrated, and massaging or activating these areas can certainly support lymphatic flow. However, lymphatic drainage isn’t just about stimulating these specific nodes—it's about encouraging overall fluid movement through the entire system.
When you activate the muscles of your core, you're influencing not just the localized lymph nodes but the flow of lymph throughout the whole body. This internal "pumping" action supports the transport of lymph to the larger collecting ducts, such as the thoracic duct, which drains lymph into the bloodstream.
While focusing on specific nodes is important, Pilates offers a more holistic approach to lymphatic health. By engaging your core, you’re improving the flow of lymph all over the body, not just at those specific points.

The Role of Gravity in Lymphatic Drainage
A common question that arises is how gravity affects lymphatic drainage, especially when many Pilates exercises are performed lying on your back or with your legs elevated? If gravity makes it harder for lymph to travel upwards (like from your legs to your torso when you're standing), how does lying down and engaging your core help? This position encourages lymph fluid to flow upward toward the upper body. From a lymphatic drainage perspective, elevating the legs in a Pilates exercise creates a position where gravity supports the movement of lymph from the legs toward the central lymphatic ducts near the chest.
However, just lying down isn’t enough. Without muscle engagement, lymph might still stagnate, even with gravity on your side. Here’s where muscle engagement comes in—when you actively engage the muscles of your abdominal area, you’re adding an extra layer of pressure that helps propel the lymph fluid upwards toward the thoracic duct, which ultimately drains the fluid into the bloodstream.
Why Core Activation with Elevated Legs Works So Well
By combining gravity-assisted positioning (legs elevated) with the internal pressure created by core engagement, you’re creating an optimal environment for lymphatic flow. This combination helps the body rid itself of toxins and waste more effectively, especially after workouts or periods of inactivity.
Regular Pilates practice helps:
Increase Circulation: Through muscle engagement, Pilates boosts blood flow and lymphatic movement, helping to detoxify the body.
Promote Detoxification: Lymphatic drainage helps remove waste products, toxins, and excess fluid that may accumulate in tissues, reducing swelling and promoting overall wellness.
Improve Immune Function: A properly functioning lymphatic system is crucial for immune health, as it helps transport immune cells throughout the body. By encouraging lymphatic movement, Pilates supports immune function and helps the body fight off infections.
Pilates is more than just an exercise—it’s a global approach to health, movement, and overall well-being. By understanding how the body’s systems work together, like the interplay between core engagement and lymphatic flow, we can tap into Pilates as a tool for holistic health.

Stay hydrated: Water helps keep lymph fluid flowing smoothly. Dehydration can slow down the system, making it harder to eliminate toxins.
Dry brushing: Using a dry brush in gentle, upward strokes stimulates lymph flow and promotes circulation.
Move regularly: Activities like walking, stretching, or rebounding (light bouncing) encourage the natural movement of lymph through the vessels.
Practice deep breathing: Your diaphragm acts as a pump for the lymphatic system. Slow, deep breaths help stimulate lymph flow and improve circulation.
Massage: Manual lymphatic drainage massage gently encourages lymph movement and reduces fluid retention in tissues.
This deeper awareness transforms Pilates and these simple practices into tools for nurturing your body’s systems. Fitness becomes more than just a routine—it becomes a pathway to feeling stronger, healthier, and more balanced every day!
