💗 Honoring Breast Cancer Awareness Month: Alma’s Story 💗
In May 2024, I was diagnosed with breast cancer. From the very beginning, I knew I wasn’t going to let it stop me. My faith in God gave me the strength to believe I would be okay and that my story could help someone else going through the same thing.
My journey included six rounds of chemotherapy, a double mastectomy, 11 rounds of immunotherapy, and reconstructive surgery. Today, I’m incredibly grateful to say that I am cancer-free.
Throughout it all, HOTWORX gave me something to look forward to. I kept working, kept showing up when I could, and was surrounded by an amazing community of franchisees, team members, Performance Coaches, and members who supported me every step of the way.
Sharing my journey also encouraged other breast cancer survivors in our studio to share theirs. We supported one another, checked in on each other, and reminded each other just how powerful community can be.
My message to anyone facing breast cancer is simple: You will get through this. Focus on the positive, take it one day at a time, and never underestimate the importance of early detection. 💗🔥

🌟 September Warrior of the Month: Dione 🌟
If you had told me a few years ago I'd be healthier at 50 than ever before, I wouldn't have believed you.
My doctor recently told me, "You have the healthiest numbers I've ever seen in a 50-year-old," and said I've likely added years to my life. Those words meant everything to me.
This journey has been about so much more than weight loss. After years of pain, inflammation, obesity, and depression, I finally feel AMAZING.
HOTWORX has given me more than workouts, it gave me my health, confidence, and a community that makes me excited to show up every day. I'm so thankful for this journey and everyone who's been part of it. ❤️🔥
