Join Our Community
When you join a program, you also join a private group of women who are working toward the same goals. The community is where you can share your progress, ask questions, and stay consistent with support from people who understand what you’re working through.
Inside, you’ll find active conversations every day, live calls to help you adjust and refine your training, and a place to stay accountable without feeling judged. Many women say that the community has been one of the most valuable aspects of their experience, as it keeps them focused and reminds them that they are part of something bigger than themselves.
You can log in at any time to check in, connect with others, and get feedback from me and the rest of the group.

“A big warm hug from someone who isn’t afraid to kick your ass.”
“Amazing… She’s supportive and challenging at the same time. Syd offers modifications for a wide range of abilities. I always felt successful even when I knew I was using much lighter weights than the rest of the group.”

About Sydney Rose Miller
Hi. I’m Sydney Rose Miller, founder of SBox Training.
I was born and raised in New York City and began my career as a high school English teacher before transitioning into fitness full-time. Over the past eight years, I have lived and coached in Los Angeles, London, Dubai, and New York. I help women train with strength, skill, and focus.
I am a lifelong athlete, a competitive boxer, and a certified personal trainer, nutrition coach, and breathwork instructor. My approach combines movement and mindset to help you feel strong in your body and clear in your mind.
Boxing brought me back to myself. It taught me to trust my instincts, own my strength, and stay grounded under pressure. I offer my clients a space where they can challenge themselves, build discipline, and feel fully present.
I am here to help you train with confidence, develop skills, and see what you are capable of. Let’s get started.
