8TH DAY GYM HISTORY & PHILOSOPHY

Built on a foundation of passion for movement by two-time Olympic qualifier Joe Cebulski, 8th Day Gym has never stopped pressing forward. Established in 2010 with just two members (Shelli and Ben) and a meager room to train in, 8th Day has now grown to over 500 members and a fully equipped 30,000 sq. ft. facility in the heart of downtown Grand Rapids.

We’ve achieved this by cultivating a community that values the knowledge of our staff, enjoys the creativity woven through every aspect of their experience, and appreciates the investment made into equipment and space.

Alyssa McElheny — 2026 HYROX World Champion

Alyssa McElheny made her HYROX debut at Las Vegas in February 2026 with a 1st place finish in the Pro Women’s division. What followed was one of the most impressive first seasons the sport has seen.

Over the course of six races, Alyssa collected three individual wins — Las Vegas, Toulouse, and the HYROX World Championships — along with a 3rd place finish in Warsaw and a 3rd place finish in Glasgow. She capped the season by crossing the World Championships finish line in 56:59, claiming the title of 2026 HYROX World Champion in the Elite Women’s division.

From debut to world champion in a single season. Congratulations, Alyssa.
