SGX, much like its mother Spartan Racing, is about setting new standards and defeating the ill-informed, self-imposed limits we all create for ourselves on a daily basis.

Improve your focus and confidence.

Expand your personal power.

Cultivate discipline, drive, and determination.

SGX isn’t just about exercise – it is about life transformation.
