Our commitments
What We Promise Each Other
Four of the promises members and coaches make to one another.
Community first
Everybody Matters
Serve the community and it will serve you back. Be open to grow physically, mentally and emotionally. We are here for each other.
Hospitality
Say Hello First
Don't know someone? Introduce yourself and check in with them. Make guests feel at home.
All in this together
Nobody Packs Up Early
No equipment goes away until everyone is done. Cheer people on or join in. We have all been there and know what it is like to be last.
This place is yours
Create Something Special
Bring a great attitude, work hard, and create something special. Spread gratitude.

CrossFit
Scaled for Beginners. Built for Athletes.
Constantly varied, high intensity, functional movements. Three things make it what it is.
01
Functional Movements
Pushing, pulling, squatting, lifting. What your body was designed to do in real life, not on a machine.
02
High Intensity
Interval training principles that build power output and endurance in less time.
03
Constant Variety
Weightlifting, gymnastics and conditioning mixed, so you rarely do the same workout twice.
Our story
It Started as an Idea at Plymouth Foam.
CrossFit reached Plymouth as a business case study in a Harvard program. David Bolland tried it in Sheboygan, brought colleagues from Plymouth Foam along, and in 2018 the idea became a gym. He and Wendy Bolland have owned it since 2020.
You came for the fitness. You stay for the community.
