Are you ready to discover what you’re truly capable of—in body, mind, and spirit?

If you're a martial artist in Ann Arbor or anywhere nearby, this is your invitation to test your limits at one of the most intense, rewarding training events of the year: the 2025 JMAC Crucible.

What Is the JMAC Crucible?

This isn’t your average martial arts seminar. The JMAC Crucible is a 12-hour, deep-dive training experience that combines disciplines like striking, takedowns, throws, and grappling. From the moment 

the clock starts at 6:00 AM until the final bow at 6:00 PM, you’ll be immersed in a physically demanding and focused environment.

But, it’s not just about technique. Throughout the day, you’ll tap into meditation practices, mental conditioning, and sports psychology to sharpen your focus and build resilience.

You can’t leave. You won’t quit. Nobody walks away unchanged.
