Hey there!
Looking for a partner on your strength journey?


Here’s a little bit of my story:
I started my strength journey because I wanted to be a better dancer. Back in 2015, I was improving my dancing all the time, but there was still a missing link that would help me get to the next level. I started going to a gym, but I had no idea what I was doing and didn’t feel like I got enough instruction from the class coaches. One day I unexpectedly found myself in a weightlifting class where the coach took the time to make me feel comfortable with the new exercises. I loved it!

I found coaches and a community that made me feel so welcomed at the beginning of my strength journey. Adding strength training into my life made me feel empowered and more capable of doing more of all the activities I loved like dancing and hiking. Once I got certified as a personal trainer in 2020, I knew that I wanted to create an accessible strength training environment that made people feel welcome and empowered!

My name is Sarah;
my pronouns are she/her/hers.
It’s great to meet you!

There are as many different types of bodies in the world as there are colors. Just like everyone has their favorite colors, everyone’s body moves in a different way. Each person has their own strengths, limitations, likes, dislikes, and goals. You are the expert of your own body, and your training should match that!

A lot of times fitness is portrayed with dark colors, but I want create a space that encourages the joy and brightness that fitness can bring to your life. Many coaches tell you what to do and use toxic fitness ideas to push you past what you feel comfortable with or enforce goals that don’t align with your own. Not in this space! When you join one of my training programs, I don’t tell you what to do; we partner to create a dynamic program that fits your body and your goals. Learn how to embrace your uniqueness so you can shine like the beautiful bright colors of the rainbow!

It's a colorful world!

Fun Facts About Me

My favorite breakfast food is french toast.

I used to work at a piercing studio. It didn’t start my body mod obsession, but it definitely helped it along!

My favorite colors are ultramarine, lime green, and gold.

Strength is for everyone!
The fitness industry has an inclusion problem. Many people don’t see others who look like them when they walk into a gym or search online. I believe fitness is for all bodies, and I strive to make my training as accessible and inclusive as possible. Everyone is at a different part of their strength journey, and your lived experiences affect your relationship with body movement.

As a member of the Body Positive Fitness Alliance and supporter of Fitness 4 All Bodies, I am constantly learning to be better and create a safe space for those wanting to gain strength and move more. Fitness should be a kind and accepting place that meets people where they’re at, not an exclusive and alienating place that always demands more.

For more, please read the Community Guidelines that everyone receives when they join one of my programs or groups. If you have any questions or concerns, don't hesitate to reach out! Email me at sarah@siertle.com or use the contact page and I will respond as quickly as possible.
