SOAR Challenge: Wiggles

Challenge due by September 8, 2026**

Wiggles look simple until you try to move smoothly across the floor without pushing, hopping, or losing your rhythm. This ground-movement drill—also called Yoko Ebi or Side Shrimping in the linked reference—requires your shoulders, hips, core, and legs to work together.

The goal is not to thrash across the mat as quickly as possible. The goal is to create controlled sideways travel by alternating the contact of your shoulder and hip. That coordination helps martial artists become more comfortable moving on the ground, changing position, recovering without panic, and building a rock-solid core.

Learn the rhythm slowly. Keep the movement smooth. Then build endurance without sacrificing control.

Coach’s Tips

• Practice on a clean padded mat or another surface (e.g., grass) that will not scrape your shoulders, hips, or spine.
• Begin on your back with a slight natural curve through the trunk. Keep your chin neutral rather than forcing your head forward.
• Move sideways by shifting one shoulder and then the hip on the same side. That shoulder-and-hip shift is one cycle.
• Rock smoothly between the shoulder and hip. Do not slam, flop, or bounce across the floor.
• Keep your arms and legs relaxed enough to balance, but do not use your hands or feet to push yourself across the mat.
• Practice equally in both directions.
• Begin with a small range of motion. Increase distance only after the sequence feels coordinated.
• Stop if you feel sharp pain, numbness, dizziness, or unusual discomfort in the neck, shoulders, back, or hips.
• If the full movement is not appropriate for you, use a smaller rocking motion or perform standing lateral weight shifts with coordinated shoulder rotation.
• Quality is more important than quantity. A smooth cycle counts; an uncontrolled flop does not.

Why This Matters

Wiggles develop the ability to coordinate the upper and lower body while moving laterally from the ground. The drill challenges the obliques, trunk stabilizers, hips, and shoulders while teaching the body to alternate tension and relaxation.

That matters in Tang Soo Do because martial movement does not always begin from a perfect standing stance. Students must be able to recover their balance, reposition the hips, protect the body, and continue moving with awareness. Wiggles also expose an important training truth: effort without coordination creates wasted motion. Smooth movement is faster, safer, and more useful than frantic movement.

The goal is not merely to cross the mat. The goal is to make the whole body work as one connected unit.

Rise Up!

Progress does not always look dramatic.

Sometimes progress is one awkward movement becoming smooth.

Sometimes it is learning to stay calm when the floor, your balance, and your body position feel unfamiliar.

Be patient with the process. Encourage the student beside you. Keep working until control replaces confusion.
