Swinging a golf club or turning to return a tennis ball may seem to depend primarily on arm strength. However, swinging movements rely on coordinated action across the entire body, especially the trunk muscles. Among them, the internal and external obliques, located on either side of the abdomen, play a crucial role in trunk rotation, lateral flexion, and stabilization, making them essential muscle groups to consider in sports.
Beyond facilitating trunk rotation, lateral flexion, and forward bending, the internal and external obliques support breathing and regulate pressure inside the abdomen. These muscles are essential for maintaining core stability during everyday activities and controlling trunk posture during dynamic movements.
Targeted training of the lateral abdominal muscles can improve core strength and stability. Combined with regular physical activity and appropriate dietary management, it can also support overall fat loss, potentially reducing waist circumference and enhancing waist and abdominal definition.
