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

ABOUT

My pronouns are she/her/hers.

Here’s a little bit of my story:
I started my strength journey because I wanted to be a better dancer. I was getting the advice that strength training would help, but... I didn't listen. Until I saw ⬇️ this move ⬇️ and I knew I wanted it but I definitely couldn't do it. So I joined a gym!

Y'all, I had NO idea what I was doing. I was looking all over the room trying to copy the other people in the classes thinking "How tf am I supposed to squat???" It wasn't until a few months later when I accidentally ended up in a weightlifting class that I started getting answers. My new coach took the time to actually teach me the different exercises so I felt more confident. I started getting way stronger! It seemed like all of a sudden I could do things I couldn't do before! And it really did improve my dancing. The rest was history.

Once I got certified in 2020 and starting this business, I knew I wanted to help people feel as welcomed and comfortable as my coaches did when I was brand new. I wanted to create a space where people could truly learn how to lift weights from the very beginning.

My name is Sarah;
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 coaching 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 go out and live your full color life!

It's a colorful world!

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.
