I invited Erwin to host a yoga class for our staff, and he did an amazing job breaking down each movement, especially for our beginners. His guidance was clear, patient, and engaging.

Highly recommend Erwin’s yoga classes!

Erwin is the BEST! He’s incredibly patient, highly knowledgeable, and consistently encourages me to push/challenge myself in a safe and mindful way. His guidance has helped me improve my form, build strength, and feel more confident in every practice. I can’t recommend his classes enough

I feel so lucky to have the chance to attend Erwin’s yoga class. He is positive, uplifting, and makes sure everyone in attendance feels comfortable with the moves. I especially loved how he tailored the class to fit our needs: from couch potato’s, to hiking enthusiasts, to families and kids. I can’t wait to take his class again! Erwin ROCKS!!

This class was a blast! The music was energetic and fun to vibe to. The class was easy to follow and as a beginner, I would definitely recommend it! I enjoyed that the class had pace, but you could also do it at your own level and take breaks when needed. A cool-down was definitely needed after a good workout! Erwin was friendly and I liked how he was encouraging throughout the entire class!

Love Muir Rock Fitness & Yoga!
I’d been searching for a gym that fit my work schedule, wasn’t too far, and could help me train consistently for my Spartan race. I toured so many other gyms and nothing felt right—until a friend from church recommended this place.

I absolutely love the Yoga Sculpt series that Coach Erwin teaches. When I told him I was training for a Spartan, he immediately shared his knowledge and even tailored parts of the class to support my goals. Coach Erwin is incredibly supportive of all his students and always brings creative, innovative techniques to make sure everyone gets the most out of each session.

Whether you’re getting back into working out, totally new to fitness, or someone who has been racing for years, his workouts meet you exactly where you are. He challenges you, encourages you, and makes sure every class feels accessible yet effective for all levels.

Thanks to staying consistent in these classes—and Coach Erwin’s expertise in racing, yoga, and Pilates—I was able to finish my Spartan race strong. Every workout feels well-rounded, challenging, and truly intentional. I’m so grateful I found this place!

This class is more than worth the price. It's always a good full body workout in a slightly heated and humidified space. Very nice amenities- mats are available to borrow, there's refrigerated water, and class ends with a nice refrigerated towel with eucalyptus oil to end class.
