Hello, underwater lovers!


What you’re about to read is a doorway—a glimpse into the ocean of thoughts, lessons, and wild experiences that make up The Depth Collector series.


The Depth Collector Book Series – Two hardcover books with intricate gold detailing, featuring a nautical compass design. Book I has a deep blue cover, while Book II has a teal cover with an octopus tentacle intertwined in the compass. Both books are set against a golden maritime-themed background, symbolizing exploration and the depths of freediving.

Hip Flexor Strength: A Key to Enhanced Performance in Freediving and Swimming


Living on Xiaoliuqiu, a stunningly beautiful tiny island off the southwest coast of Taiwan, presents us with two main freediving options. For dives deeper than 35m, we need to take a boat trip. Alternatively, we can access dive sites directly from the shore, which is perfect for teaching or practicing exhale dives However, there's a catch: Our mooring buoys are situated 450m away from the beach. I often tell my students half-jokingly that the swim out to the buoys is their first endurance training session.


For a long time, I found myself pushing the buoy while resting my arms on it and keeping an eye out for any nearby boats. Maintaining this improper posture over hundreds of meters, and for years, inevitably led to strain on my lower back and hip flexors. As a result, muscular imbalances and discomfort became a very real and persistent issue for me.

 The Hip Flexors

Yet, as is often the case, this cloud had a silver lining. The need to address these issues became clear; living with pain wasn't an option I was willing to accept. This realization propelled me into researching and understanding the crucial roles of hip flexors, posture, and balance in freediving. As a result, strengthening and conditioning my hip flexors have become integral parts of my training. This focus goes beyond merely boosting my diving performance—it's also about alleviating the strain on my lower back and legs, ensuring a more balanced and pain-free diving experience. The hip flexors are essential for flexing the hip joint and significantly influence the lumbar spine and knee joint.


Impact of Overloading the Hip Flexors


The repetitive kicking motions, particularly with your beautiful long fins, place a considerable load on the hip flexors. Overloading these muscles in such a limited range of motion causes an initial feeling of tightness in the area, which can rapidly progress to pain during and after a session. Excessively tight and painful hip flexors can impair performance by decreasing streamlined positioning and kicking strength. They can also lead to other injuries like anterior hip impingement and lower back pain.


The Importance of Conditioning Hip Flexors


Speed and Power

     Strong hip flexors, hamstrings, and glutes are crucial for speed. They enable faster, more powerful forward leg movements and upward knee drives, which are essential in freediving for efficient propulsion and movement.


Preventing Injuries

     Given the intense demands of freediving, athletes are prone to hip flexor injuries. Weak hip stabilizer muscles can lead to issues like Iliotibial Band Syndrome (ITBS) and patellofemoral pain syndrome.


Stability and Posture

     The hip flexors are core muscles that stabilize the pelvis and spine. This stability is vital for maintaining a streamlined body position in the water, reducing the risk of lower back injuries.


Effective Conditioning and Training


Exercises such as high knees involving controlled movements are excellent for activating these muscles. Such activation is vital for generating power and maintaining effective body positions in the water. However, more than merely stretching these muscles is required; strengthening them is also necessary to ensure they function optimally in demanding aquatic sports like freediving.
