Description Technical Specs Users Guide

Take Charge And Lead The Way:

The Commando balance board is large and strong just like you. Take charge of every situation and hone in on your skill set. Designed for the tall user who can unleash an athletic and powerful commanding force. Utilizing the full potential of this board and mastering heavy duty exercises will rank you at elite status. This is the most versatile balance board for full body training, exercise variety and extreme range of motion.

Elite Status Training:

This Large size balance board is not for the weak or timid. Requiring a wide stance for smaller riders fires up gnarly muscle activation and control. Very tall riders finally have a board that fits their natural stance and allows functional training. Upper body moves are comfortable and give you an infinite range of positions. With a large rail space there is plenty of room for 2 Balls or Half Balls for full body moves.

Balance On These:

The Commando 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 to expand your exercise routine.

5" Medium Balls: These Balls are the best size for beginners and getting used to the large riding surface. You will have enough space to ride and carve turns without grounding the board. You will eventually want to progress to a larger ball size if you have mastered the 6.5" Ball.

5" Large Ball: The Large Ball is for intermediate 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.

" Extra Large Ball: This Ball is for advanced riders who have completely mastered the 6.5" Medium Ball speed and 8.5" Large ball weight. At 20 pounds this ball carries so much momentum and inertia once you get it going. It takes your absolute concentration and muscle control to really ride this ball hard. Being 10" inches off the ground is awesome for big turns and feeling like you are floating on air.

8.5" Half Balls:
This size Half Ball is the best size for the Large Commando Board. 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 Single Pivot, Thrasher and Rock and Roll combos. Use a 6.5" Medium Ball and 8.5" Half Ball for the Big Drop combo.

Resistance Bands: Increase your postural control and spine stability with Resistance Bands. Simply loop the straps around the board and attach the bands and handles. Adding the upper body control increases your muscle activation, focus and overall training effect.

Elysia's Notes:

My absolute favorite balance board for total leg domination with the 8.5" Large Ball. I am on fire after a few minutes and then I hold that deep and wide squat to wake up my entire body. I love the huge range of motion and ride area of this board. The push-up sequence gives me so much shoulder motion and really activates my spinal control. My favorite board size for full body training with Resistance Bands and positions with my hands and feet on the board.

  1. Rocker Board: 2 Half Balls

5 of 5 This is the gold standard November 28, 2021
Reviewer: Kent Lysell from Delta, BC Canada  
This is the gold standard of balancing atop a board, with a ball underneath rather than a roller.

It will take you some time to master this skill, but once you do, you can add variety to your exercise regimen to maximize your indoor preparation to perform any board sport. The reward will undoubtedly be better control of your board whether it's on snow, water or land!

5 of 5 I love it, so so fun!!! July 3, 2020
Reviewer: emmaleigh paul from Ypsilanti, MI United States  
Thank you so much for providing this amazingly fun and dynamic balance challenge!!! After 6 months of use, i can safely say that I love it!

Some background, I am not an athlete, I don't even work out at all because it's too boring.  But know what's not boring? This si-board!! Somedays I can't keep myself off the darn thing!

It's like surfing or skateboarding  (i assume...) without the fears of drowning, sting rays, or being hit by a car. Perfect! It's also like dancing.

So, now the si-board and the wheelbarrow in the garden represent my entire workout regimen, and guess what? I'm getting kinda jacked (for me anyway, lol!). I also just feel good and confident. The possibilities feel endless.

Word to the wise, I would definitely  recommend starting slow if you're new to balance boards. It's super intimidating at first. I relied on a chair to spot me for a good 2 months. But once you get the hang of it, it's the best! Thanks again!!

The Commando SI Board becomes simply the greatest single indispensable training piece to maintain and build one's wave-surfing skills and strength; long and steep fast waves alike! It is faithfully precise in response - and the practice rewards are found across an amazing breadth of elements, which one can assemble at any level to suit multitude of athletic performance, recreational or therapy goals.

5 of 5 Fun and challenging February 7, 2017
Reviewer: Joe from Minneapolis, MN United States  
The Commando board is one fun, challenging ride!  The wide stance is very different from the Freestyle board, and it takes more muscle and weight commitment to control the Commando.  I am very, very happy that I now have both boards.  

Also, the workmanship is impressive.  Great product!
