Surf Inspired:
The Surf Original takes dry land training to a new level. We shaved weight off the nose to carve a turn with quicker precision compared to our elliptical models. The stable fish/swallow tail keeps your base grounded as you whip this board in, out and around. Bump up your dry land training and your next session will be amazing.
Dominate Every Wave:
Surfing indoors just got easier. Plenty of space for two balls or half balls for upper body exercises and full body coordination. Practice pop up moves, cross stepping and getting deep into the tunnel. This board easily allows a variety of positions and will continually challenge your sense of balance.
The Surf Original features a steel rail system that allows you to create 16 different types of boards. A perfect balance board for learning skill progression. Create your own unique combo that suits your needs. Add Balls and Half Balls for your training. Features a steel rail system you can attach Resistance Bands or a BOSU to expand your exercise routine.
5" Small Balls:
These Balls are fast and keep the board moving for beginner riders. They will keep the balance board close to the ground for easy stopping. Use two for a double pivot board and have a lot of forward and backward motion for skill progression and quick foot work. Use one ball for a multi-direction board for a high level of movement.
6.5" Medium Balls:
These Balls are a better size for riding on one ball compared to the 5" Ball. The height is good for carving turns and to transfer weight from foot to foot. Using two balls under the board gives you lots of side to side tilt when in a deep stance.
8.5" Large Ball:
The Large Ball is for advanced riders who have great control and coordination. Being 8.5" off the ground gives you huge turns without grounding the board. The weight also carries your momentum and requires greater muscular strength to control this fast moving board. Expand your set up with this ball as you progress.
8.5" Half Balls:
This size Half Ball is the best and will give you enough tilt and ability to rotate. Use one for a wobble board tilting in all directions. Use two and create a rocker board for basic movement. Half balls allow you to progress from the basics of balance or multi-task in complex motions as you progress. Use a 5" Small Ball and 8.5" Half Ball for the Thrasher and Rock and Roll combos to simulate rough water conditions. Use a 6.5" Medium Ball and 8.5" Half Ball for the Big Drop combo to simulate unpredictable training with quick saves.
6.5" Half Balls:
This size Half Ball is best suited for beginner needing less tilt. Combine with 3" Mini Balls to create the Thrasher or Rock and Roll combo. Combine with the 5" Small Ball to create the Big Drop combos. Both of these simulate rough water or unpredictable conditions.
Resistance Band System:
This Original board features a steel rail system that anchors the Resistance Bands System. Perfect for adding greater body awareness and posture control as the bands pull you down toward the board. Use the handles and foot straps to take any exercise move and expand the challenge.
BOSU Strap System:
Place your board on the BOSU and secure it with our strap system. The unique movement is gentle and feels like floating on water. Great for movement sequences from quadruped to full standing, landing jump progressions or partner drills.
Elysia's Notes:
I love the Surf Original with the 8.5" Large Ball and so do advanced riders. There is something about being high off the ground and letting the weight of the ball carry your momentum until you are hanging on by a toe. Pop-ups and deep stance training is great on the 6.5" Medium Balls. The larger board size compared to the Freestyle Original gives me a little more room for board grabs and wide stances.

1. Rocker Board: 2 Half Balls
Place Half Balls flat side up for faster tilt. Using two creates a Rocker Board that tilts in 2 directions - Left and Right for example. The farther the Half Balls are from one another, the more stable the surface. You can place them very close together for more challenge. This is great for holding a position and rocking the board left and right to activate your muscle coordination.
2. Wobble Board: 1 Half Ball
Place 1 Half Ball under your board and it will tilt in all directions and allow you to twist the board. Place in the center for an equal weight distribution. Place to the side and you will activate the side directly over the Half Ball. This is great for developing strength on one side if it is weaker or unable to function the same after an injury.
3. Single Pivot Board: 1 Half Ball and 1 Ball
Place 1 Half Ball under the left side of the board and 1 Ball under the right side of the board. The left side will tilt front to back and the right side will pivot or slide forward and backward. A great progression to learning how to activate hip rotation on a moving board on one side of your body.
Best set up: 3" Ball and 6.5" Half Ball or 5" Ball and 8.5" Half Ball
4. Double Pivot Board: 2 Balls
Use 2 of the same sized ball under your board to activate each side in rotation. Placing the Balls close is more difficult. You will get multi-direction motion without the extreme tilting from left to right feet. A perfect combo for advanced skills like surf pop-up, quadruped, deep squats and adding difficult upper body battle rope exercises while maintaining balance.
5. Multi-Direction Board: 1 Ball
The heart of the Si Board is riding on 1 Ball for a multi-direction platform. The freedom to move left/right, front/back, twist, diagonal, clockwise/counterclock and 360 spins all at the same time. This is the most advanced balance board skill to learn fine motor skill and full body awareness.
6. Rock and Roll: Small Ball inside of Half Ball x 2
Placing a small Ball inside the Half Ball creates two moving surfaces. The small Ball rolls around inside of the Half Ball. The Half Ball is placed flat side up and creates a rocking or wobble motion. Four moving surfaces that keep you level and don't allow the board to roll to extremes. You feel all surfaces continuously knock into each other abruptly. Perfect for deep stance endurance simulating rough water and windy conditions.
Use these combos:
7. Thrasher: Small Ball inside of Half Ball x 1
Placing a small Ball inside the Half Ball creates two moving surfaces. The small Ball rolls around inside of the Half Ball. The Half Ball is placed flat side up and creates a rocking or wobble motion. Two moving surfaces that give you extreme tilts in all direction with slight board rolling. Perfect for holding your push-up position against an opponent and a narrow squat with very quick foot reactions.
Use these combos:
8. Ball Big Drop: Medium Ball fixed tight inside a large Half Ball
Wedge a Ball inside the Half Ball so that the two parts do not move. You have two different sized balance points and this gets you up high off the ground. You will teeter/hover around and just as the Half Ball gets to the edge you will feel a fast drop to the ground. Reaction to this feels like a sudden drop and being able to control landing on you sport board.
Use these combos:
Add Resistance for Greater Body Awareness:
Mastering your Si Board on the Balls and Half Balls is a big challenge. Now it's time to add resistance and fight the downward forces towards the board. Anchor the straps anywhere along the steel rail, attach the resistance band and then add the handles or foot straps. You can have resistance from any angle and keep your body guessing what's next. This stimulates more posture awareness and strength to keep your position.
Combo With Your Sports Equipment:
Make it more sport specific by strapping your sports equipment to the end our resistance band. Imagine a tennis racquet, baseball bat, steel mace or kettlebell in your hands being pulled downward toward the board. Then keep your position with the added balance challenge of any of the 8 board set-ups mentioned above. Sounds like one awesome exercise!
Gentle Movement Flow and Landing Your Jumps:
Sometimes you need a more forgiving balance board compared to our very responsive Balls and Half Balls. Strap your Si Board to a BOSU to get the sensation of floating on air. Movement flow is easier and more fluid. Perfect for partner drills, going from horizontal to vertical exercises, beginners learning balance and advanced athletes adding jumps and other equipment.
Use A Burst Resistance Stability Ball:
You can also add a burst resistance Stability Ball under the board and strap it in. We use a 55 cm that is deflated 1/4. This is a very advanced set-up when standing or jumping on the board. This is a great skill progression for learning push-ups, dips or bridges.
Please note:
Use a BOSU and burst resistant Stability Ball in good condition. Check for defects or damage before using and follow all safety guidelines. We are not responsible for damage to your exercise equipment or injury. Exercise within your skill level, with a spotter and safety equipment.
