Abby Jung has been involved in different dimensions of fitness since middle school. She believes in the power of positivity and encouragement. Abby believes in the theory of working smarter, not longer. “With focus on proper technique, we make health and fitness goals attainable and enjoyable! I love challenging and encouraging people out of complacency.” She wants people to know anyone can do CrossFit. “There’s a misconception about CrossFit that everyone is already in shape when they join and we focus mainly on strength. That’s not true. Many people can’t do a pull up or a proper air squat when they join!” Abby safely used CrossFit during her 2 pregnancies and understands the importance of scaling options. Abby enjoys working with athletes of all different levels: people who are wanting to become fit to live long healthy lives, and people who want to compete. Abby placed 9th in the state in the masters division during the 2017 CrossFit open. 


Abby’s Favorite Movement: squats - any type! You get the most bang for your buck with the full body movement.

She loves the competition side of CrossFit and competes in many local competitions including the Granite Games in Minnesota.

Sylvia began her love for Olympic Weightlifting after watching her first local meet in 2014. She has competed in several local and state meets, placing her as the Wisconsin state record holder for Masters in her weight class. 

She enjoys working with individuals that are new to the sport and her ultimate coaching goal is to have her athletes reach their fullest potential to qualify for Nationals. Her interest in sports and fitness has her constantly learning about strength and nutrition to fuel for performance.

In her spare time, Sylvia plays on several softball leagues, coaches her daughter's sport teams, and is the biggest cheering fan for her boys’ teams. If you’re trying to get out of doing burpees, she can always be bribed with donuts, a cup of coffee and funny memes.
