Legs spiraling out for grounding

Seated Spinal Motion: Engaging the Spiral Lines

During seated spinal motion exercises, you will elongate the spine by actively engaging your legs. By narrowing the pelvis, you create space for it to move, which frees up movement in the spine without losing support from your grounded feet and legs.

To begin, find a comfortable, wide-legged seated position. Try to press your feet into the floor to ground yourself. If you only press your legs linearly into the ground, it won't activate the muscles around the pelvis in a harmonious way. However, if you spiral your legs outward as you press into the ground, you will experience a narrowing sensation in the pelvis and feel an elongation throughout your spine.

The Anatomy of the Spiral

To understand how to access this spiraling sensation, we can look at the Spiral Line of the myofascial meridians from Thomas Myers’ Anatomy Trains.

1. The Ascending Pathway: Ground down behind the first metatarsal (the ball of the big toe), spiral up through the front of the shin (Tibialis Anterior) to the outside of the knee (Lateral Tibial Condyle), and travel up the side of the thigh (Tensor Fasciae Latae and Iliotibial Tract) to the hip bone (ASIS).

2. The Descending Pathway: While the anatomical line continues upward, let’s look at the reversing loop of this spiral within the lower body. Starting at the sacrum (Sacrotuberous Ligament), it travels to the sit bones (Ischial Tuberosity), wraps down through the lateral hamstrings (Biceps Femoris), moves into the calves (Fibularis Longus), wraps under the outside of the foot, and anchors back at the bottom of the first metatarsal.

Finding the Loop

The sensation in your legs should feel like energy rising in a spiral: lifting from the ball of the big toe, crossing the front of the shin, and moving up the outside of the thigh to the hip bone. At the same time, you are reaching down through your sit bones, down the back of the legs (the hamstrings and calves), and back into the first metatarsal.

The Result: It is a continuous loop. This is why your legs will feel as though they are pulling upward and reaching downward simultaneously.

This dual action creates a secure, stable foundation that allows you to move your spine safely and freely, helping you find true confidence in your movement.
