Si Boards

California-based athletic trainer Elysia Tsai put her two decades of experience into developing a better kind of balance training system—one that could serve a variety of athletes, skill levels, and training goals. The result was this Freestyle Original model of the Si Board—a concave, grip-friendly riding surface built for anyone 5’4″ and taller and up to 400LB.

Made in the USA, Si Boards are designed with a unique steel rail system positioned underneath the 36″ x 18″ wood balance board, enabling multiple customization options for changing the difficulty level and speed of movement. There are two combo packs available for adding compatible urethane balance balls and other board accessories.

Basic Combo – 4-in-1 System to create 4 unique ride surfaces. Includes:

• (1) Freestyle Original Board – Medium
• (1) 5″ Small Ball
• (1) 8.5″ Half-Ball

Speed & Strength Combo – 16-in-1 System to create 16 unique ride surfaces.

• (1) Freestyle Original Board – Medium
• (1) 6.5″ Medium Ball
• (2) 5″ Small Balls
• (2) 8.5″ Large Half-Balls
• (1) Resistance Band System

Both the 5″ ball (2.5LB) and 6.5″ ball (5.5LB) are multipurpose and can be used separate from the board as unbreakable high rebound medicine balls. They’re also great as mobility tools for trigger points and tissue release.

The Science Behind Si Boards

Si Boards are based on multi-direction movement riding on top of a solid and responsive ball. The full muscle contraction, complete body awareness, joint stability, and ability to react to outside forces creates a very efficient training effect. Using the half-balls is equally effective, allowing you to target strength deficiencies and perform complex training moves without the board rolling (this makes the half-ball a good option for progressive beginner’s training, as well). Athletes can add the resistance bands to increase the effect of gravity, as the downward pull of the bands requires the user to respond with greater posture awareness and stability.

This is the perfect balance training system for getting all of your systems to engage before a training session. You can also work it into your circuit. From rehab work to high-level, fully functional training, Si Boards allow you to set your own pace, experiment with ride stances, and develop both upper and lower body strength with improved balance and fluidity of movement.
