Location: Vancouver, Unceded Coast Salish Territory

Ruby Smith Díaz was born to Chilean and Jamaican parents in Edmonton- amiskwacîwâskahikan. She is the owner of Autonomy Fitness and has found her passion working as a teacher, facilitator, multi-disciplinary artist, and through supporting marginalized communities in feeling powerful and grounded in their bodies.

Ruby's body positive personal training service is dedicated to empowering folks to feel their best in their bodies, on their own terms. Autonomy Fitness offers support in gaining strength, power, endurance, and confidence while leaving diet-talk, fatphobia, transphobia, and eurocentric body standards at the door.

Autonomy Fitness welcomes and centers the participation of Indigenous people, Black people, People of colour, queer fam, gender binary breakers, radicals, and beyond- in any shape and at every size. Ruby currently operates out of Fox & Unicorn Gym in Vancouver, Unceded Coast Salish Territory. This space is 100% wheelchair accessible, with all-gender bathrooms.

Size Chart

We pride ourselves on a superior fit. Use this chart to find the right size Superfits for you. 

Bottoms: It's all about the hips! Measure your hips at their widest point using a soft measuring tape. Between sizes? If your body is hourglass shaped, size down. If you are more apple or box-shaped, choose the larger size. 

Bras: Measure your bust at the widest point. If you are between sizes and have cup size A-D, size up. For cup size DD and above, size down.

OUR SUPERFIT GUARANTEE: Every body is different. We want you to love your Superfit products. If you prefer another size, we will exchange it for free! More info >>
