Katie (Siggy) Sigurdson

Katie Sigurdson (known as Siggy at the gym) is the owner of Jolt Fitness, a mission-driven functional fitness gym providing private, group and nutrition training services rooted in Exeter, Ontario. With over a decade of experience across Canada in the fitness industry, Siggy and team are on mission to build resilient bodies and create high quality life in our community.

Siggy's path to building Jolt was forged through her own personal struggles, navigating obsessive exercise and disordered eating behaviours while competing in high-level competitive sport. That raw, lived experience became the non-negotiable foundation of Jolt's identity: true strength is about mental and physical resilience, not just aesthetics. It's a story of building strength to overcome life’s toughest challenges and pursuing the best version of yourself. Our vision is to re-shape how people perceive fitness and change the narrative of the fitness industry.

Since launching Jolt Fitness in 2020, Siggy has trained thousands of different bodies and built a team of 15 that proves rural communities don't just deserve access to high quality fitness — they can lead the way in shaping it.

Recognized as a South Huron Entrepreneur of the Year, a Women of Influence nominee, and a three-time Chamber of Commerce award winner, Siggy is passionate about showing up for her community and proving that big vision can happen in small rural communities.
