About Moxy

Made to move—with weight on your hips, not your shoulders.

Moxy Weighted Corset has a specialized design that offers a hip-loaded alternative to bulky, shoulder loaded weighted vests. Co-designed by a medical corset maker, Moxy lifts the ribcage away from the pelvis making it safe for osteoporosis users and will ensure proper form for everyone. Float through your walks, runs, tennis and golf sessions with a comfortable, lifted fit.

Why we made Moxy

We love resistance training—but we didn’t love how traditional weighted vests can feel: heavy on the shoulders, restrictive through the upper body, and bulky for everyday movement.

The problem

Weighted vests can load your shoulders—and your patience.

Many vests concentrate weight high on the body. That can mean shoulder/neck strain, awkward bounce, and a “gear-heavy” feel that’s hard to wear consistently.

Shoulder and neck strain

Bulky, restrictive fit

Hard to move naturally

Increase risk of spinal compression

Our approach

Hip-distributed weight that stays close and stable.

Moxy is designed to carry resistance lower—closer to your hips—so you can train with a more natural feel and less upper-body load.

Hip-loaded distribution / decreased risk of spinal compression

Less bulk, more freedom

Our Mission

Empower woman to change the world


My dream for myself, my daughters and every woman around the world is for us to be courageous and strong and feel that our presence matters: we’ve got moxie! The Moxy Weighted Corset allows you to do just. When wearing the Moxy weighted corset you increase strength, stand tall and move with purpose, as the Moxy corset elongates the spine and lifts the sternum. Moxy strengthens you, so that you can realize your dreams.

For bone health

Supportive training for women thinking about bone health.

If you’re navigating osteoporosis or simply prioritizing bone health, adding resistance can be part of a strength-forward lifestyle. Moxy is designed to strengthen you with a specialized, sustainable design that creates proper posture by lifting the ribcage away from the pelvis and placing the weight load on the hips. This creates space in the spine thus avoiding increased risk of spinal compression.

Comfort that helps you show up

A stable, hip-loaded feel can make resistance training feel less intimidating—and easier to repeat.


Movement-first design

Made for walking, running, tennis, and gym training—so your resistance can fit your routine.


Confidence without the bulk

Less “equipment” energy, more everyday momentum—so you can train in a way that feels like you.


A gentle note on safety

Everyone’s body is different. If you have osteoporosis or any medical condition, talk with a healthcare professional before starting or changing a weighted exercise routine.

Our values

Confidence looks good on you.

Confidence

Our design is sexy and flattering. No matter your mood, you’ll feel your best and know that your building confidence while looking amazing doing it!

Strength is a practice. We’re here for the reps, the rest days, and the long game. Believe in yourself each day and show the world you’ve got Moxy!

Different bodies. Different goals. Same right to feel powerful in motion.

What makes it different

Hip-weight distribution • Less bulk • Comfortable fit • Two styles: athletic + fashion

Founder Bio

Dawn Theilen — Sonoma, California

“I’ve loved athletics since the age of 3.”

Being raised in Lake Tahoe and San Diego, skiing, hiking, swimming and other activities were a way of life for Dawn Theilen. However, gymnastics took center stage and at the age of 11 she competed for the Reno team.

This love of movement became a driving force in her life, which led to her passion to become a personal trainer over 30 years ago. She shares this love of fitness with her husband, grown children and 3 dogs. Together they enjoy paddle boarding, kayaking and backpacking (especially in Yosemite) and live in Sonoma, CA.

Dawn’s career in fitness began in 1993 at Mill Valley Personal Fitness. While attending Sonoma State University she continued her fitness path and was certified in Spinning with Johnny G and took her bicycling expertise and completed the 520 mile AIDS ride from San Francisco to Los Angeles where she discovered a need for a stronger core.

This led her to Pilates Mat certification from the University of Phoenix. Discovering Pilates changed her teaching style to more functional and sustainable workouts. She opened her own gym, Form Body Studio in San Rafael in 2001. Form offered an array of classes and trainings, including The Fundamentals of Pilates, which she taught for the College of Marin.

In addition to her studio offerings, Dawn taught Pilates and correct ergonomics for the employees at AutoDesk and Kaiser Permanente. She also spoke at the Young Woman’s Conference in San Francisco to inspire high school girls to become small business owners.

In 2005, Dawn moved to Sonoma and began teaching workshops, personal training and leading hikes for The Sonoma Mission Inn and Spa where she remains today.

In 2019, Dawn created her own fitness style and branded it Infinite Method. Infinite Method is a blend of light weights, core, balance combinations, stretching and light cardio and TRX when available. She teaches Infinite Method at the Fairmont, zoom classes and with personal clients. You can also find her on YouTube.

Dawn’s clients would describe her as an expert in her field. She uses an intuitive approach and thrives on assessing bodies and helping them transform into a sustainable, strong vessel. Her energy is light hearted and full of compassion, but she has an eye for form and is no nonsense when the work needs to be done.

Moxy was created when Dawn’s clientele were having negative symptoms from wearing weighted vests and she began hearing complaints about how unattractive the vest were. She realized that shoulder-loaded weight compressed the spine and rounded the shoulders forward making you look slumped. So she designed the Moxy weighted corset, which has hip-loaded weight (where it belongs ) and creates space between the ribcage and the pelvis making for correct posture and a sexy look.
