I have been using the Si Board for almost a year now and it has helped my up my game as an Athlete. It exposed some holes I had in my balance and some of my stabilizer muscles. Since using the board my balance and core strength have increased significantly as well as my lifts such as front squat, back squat and deadlift. The Si board is something that I use every training session in some fashion because it is so versatile you can make even the simplest movements challenging.
