Britt McWilliams: Assistant Manager, Redmond & Personal Trainer

Born and raised in Redmond, WA, I have been involved with the fitness industry since 2012. After giving birth to 2 boys and sitting behind a desk for 7 years doing Medical Billing, I strived for a more active lifestyle. I became obsessed with Group Fitness. I hold a AFAA Level 3 Group Fitness certification and was at one time teaching up to 16 classes a week. These were of various high-energy formats including Zumba, R.I.P.P.E.D., BODYSHRED, Bootcamps, as well as a young child’s music and movement class called Zumbini.

Striving for continuing education and having a strong desire to learn, I shifted my focus to nutrition in 2014. Immediately I noticed a giant lack of coaching and positive support systems for the average individual looking to make smart choices. So I took the love, happiness and high energy aspect of my experience with Group Fitness and combined with the true science based facts of nutrition. Using real food to reset the metabolism, but catering this theory to adapt to the specific client, rather then using cookie-cutter methods. My biggest goal is to show every client I encounter that “eating clean” and being “healthy” doesn’t need to be overwhelming or scary. In fact, it should be fun! I strive to not only provide unconditional support but educate throughout the entire process so that clients can be in charge of their own lives. And that they eventually feel confident to continue making positive choices permanently.Striving for continuing education and having a strong desire to grow, I branched out my certifications to include Personal Training, Nutrition, and an endless list of specialty courses. In 2016, I became a Master Trainer for Jillian Michaels teaching other instructors the BODYSHRED format in Washington, Oregon, and Idaho. I truly believe I have found my life’s calling by being a Coach and Personal Trainer.

When is comes to our bodies, I believe in biomechanics above all else. Whether you are just starting your journey, are an experienced athlete, or recovering from an injury, we will always utilize proven science to establish and define reaching your desired outcome.

Nicole Shavlik: Yoga Instructor

I have always been a mover. A go getter athlete. That strong, go, push mentality enabled me to reach my dream. To play college softball at the Division 1 level. However, along the way I must have missed the rest, relax, and repair seminar. Because just a year and a half into my dream I had worked so hard for, it began to unravel. My body wasn’t functioning. Injury after injury left my spirit broken and my mind lost. I had no other option than to do something different. So, I took up a yoga class with the hope that it would solve all the injuries. I’ll put it this way – it did AND it didn’t work. At first, I took my athletic mentality with me into every yoga class: push, go deeper, full expression, chaturanga. Until…wait for it…yup, another injury. And another. For some reason I must have needed to learn the hard way how to rest, relax, and repair. With no other physical options, I dove head first into the healing arts, dance, yin yoga, meditation classes, and sound baths. It was a profound challenge. As I stayed consistent with my practice, my mentality began to open, soften, and change. Injuries healed and as I started moving again I did so in a whole new way. I backed off, took breaks, and listened to my body. I’ll testify that it truly healed my body, mind, and spirit. My journey still continues; however, now I feel called to share the gifts of yoga with others.

I help curious and brave individuals – who desire change – to feel, heal, and breathe so they can cultivate a transformative relationship with their body, mind, and spirit.

In my classes, I encourage you to move intuitively and offer moments of freedom to dance toward sensations that nourish your practice. We will weave movement and breath together so you can consciously connect to your body and calm the mind. I creatively sequence movements that step outside the box because if we seek to change, we must move differently. When we move differently, we think differently. And when we think differently, we can live a life that embraces change on and off the mat.

“If nothing changes, nothing changes.” –Courtney Stevens

I invite you to come to class curious about movement, each brave breath will illuminate your path towards the transformation you seek.

I’ll be with you every step of the way cheering you on, because you got this.
