John Warnek – Head Coach & Owner


John first heard about CrossFit in 2006 after a friend (a Navy SEAL) told him about At the time, John was a thrower at West Chester University, and he was always looking for new ways to increase his strength and fitness. John started following the CrossFit mainpage workouts, completing the WODs in his college gym. John loved the workouts and found they gave him great results without causing his joints to hurt the way his years of heavy lifting had done.

In March 2010 John became a CrossFit Level 1 trainer and started up a small garage gym with some of his coworkers. They did most of their workouts outdoors, even in 20 degree weather, multiple feet of snow, and pouring rain!  2010 was also the year John started competing in CrossFit. He joined the CrossFit KOP team, where his strength and leadership helped the team earn a spot in the 2010 CrossFit Games. In 2011 John qualified to compete individually at the Mid Atlantic Regionals, but gave up his individual spot to compete one last time with the team.

In August 2011 John joined up with Nikki to open Iron Cross Athletics, home of CrossFit Phoenixville. As a coach, John is known for his really tough warm ups, and for pushing his athletes to accomplish things they never thought possible.
