What key aspect does the "Mermaid" exercise focus on?

The "Mermaid" exercise primarily emphasizes lateral flexion and stretching of the spine. This exercise involves movements that promote flexibility along the sides of the torso, allowing for an extended range of motion in the spine. During the exercise, participants engage one side of their body while lengthening and stretching the opposite side, which is essential for maintaining a healthy spine and improving overall mobility.

Incorporating this type of movement can significantly benefit posture and alleviate tension in the back, as it encourages elongation and lateral movement, which can often be neglected in daily activities. By focusing on this aspect, the "Mermaid" exercise helps enhance overall spinal health, making it particularly valuable for individuals looking to improve their flexibility and protect against back strain.
