The background story
It Started as an Idea at Plymouth Foam.
Plymouth Foam’s former owner, David Bolland, first learned about CrossFit at a Harvard class which featured CrossFit as one of the many cases the program studied.
Dave shared the experience with local friends when he got back. One of those friends was Bob Travis, owner of InkWorks, who had just joined Sheboygan’s CrossFit Eastern Ridge with his wife.
Dave quickly joined and, like many others, fell for the culture and community: accountability and results in a fun atmosphere.
Together they brainstormed ways to bring CrossFit into Plymouth Foam. Working with Marty Harms, CrossFit Eastern Ridge’s owner, and Tom Matzdorf, one of its coaches, the Plymouth Foam team grew the idea from concept to reality.
You came for the fitness. You stay for the community.

Our commitments
What We Promise Each Other
Ten commitments from our athletes, and ten from our coaches. Together they make this everyone’s best hour of the day.
Community First
Serve the community and it will serve you back. Be open to grow physically, mentally, emotionally, and even spiritually. We are here for each other. Everybody matters.
Good Role Model
Know, observe, and practice the gym’s values and purpose. Compete and collaborate with yourself and others, with good sportsmanship. Give your coach your undivided attention.
On Time & Prepared
Coaches carefully plan your best hour of the day, so we start and end on time. Reserve for class in advance. If late, blend into the class without distracting others.
Hospitality
Don’t know someone? Introduce yourself and check in with them. Make guests feel at home.
We’re All in This Together
Don’t start putting equipment away until everyone is done. Cheer people on or join in. We’ve all been there and know what it’s like to be last.
Modifying & Scaling
Our coaches are happy to help you modify with lots of scaling options. Talk to your coach ahead of time so you have a plan that is safe and challenging.
Protect Yourself & Others
Always be gym aware and give people room while others are lifting or on the ground. Safety guidelines have a why behind them.
Treat the Equipment with Care
Empty barbells are set down like they are made of glass. Chalk stays in the bucket. Return everything to its place so the next class has a clean gym too.
Kiddos & Spectators
We all love a cheering section. Children and guests stay in the changing area, not the training area, so everyone stays safe.
The Place Is Yours
Bring a great attitude, work hard, and create something special. Spread gratitude.
Timely
Start and end class on time. Be at the gym 15 minutes before and after class.
Clean
The gym reflects our collective pride. It stays a clean and safe environment.
The 5 P’s
Prior preparation prevents poor performance. Know the workout, the cues, and every way to scale it.
Relentless
Coach an athlete until the movement pattern is there. If one cue doesn’t work, try another.
Protect Athletes
Mechanics and consistency before intensity. Reinforce good habits.
Preserve the Equipment
Be consistent, and be the voice of the equipment. Especially barbells.
Human & Positive
Greet every athlete by name. Relate to the person, not just the athlete. Make this everyone’s best hour of the day.
Coach Every Individual
Every athlete receives some personal attention, not just the class. Move around and use few words.
Practice What You Preach
Model the gym’s values and proper form. Be an athlete too, and part of the community.
Welcome Feedback
Keep growing through peer review and seminars. Take critique the way you ask athletes to.
Third Space
A Space for the Whole Community.
Join our StreamFit app which features a Third Space group that is open to everyone, members or not. It exists to gather ideas for non profit events, musicians, artists and speakers.
