All Out for breast cancer awareness. 💕🧡

Four years ago, Heather R. walked into OTF for the first time, and what started as a workout quickly became something more — a second family, a support system, and a source of strength.

At only 38 years old, Heather received a breast cancer diagnosis and underwent a double mastectomy. Because she chose surgery, she was able to bypass chemo and radiation — but her journey was far from easy.

"I will say that one of the first things that crossed my mind was how long I would have to take off from OTF. When I got back, I was super nervous and had no idea what I could and couldn't do. The coaches were amazing and gave me alternatives. I shed a lot of tears those first several classes after realizing my body was different now. The coaches were very attentive and encouraging when I was feeling defeated." But she found her strength again.

Heather also leaves us with an important reminder: “If you’ve been putting off your mammogram, consider this your sign. Make the appointment. Do your self-exams. Take care of you.” 💗

This Breast Cancer Awareness Month, we honor Heather — and everyone fighting, surviving, and thriving. Heather, we’re so grateful for your courage, your voice, and your presence in our OTF family. 🧡

Day 5 of Hell Week: Chains of the Coven. 🧙‍♀️ From the very first second, the witches had us bound. ⛓️ The Spell of Restriction held us tight — inclines stealing our speed, bands clipping our range, rows stalling us like a red light. But every break in the chains was a reminder: Freedom never felt so good.

Tick… tock… the Spell of the Clock was cast. ⏳ Day 4 of Hell Week: Omen of the Hourglass became a race against the witches’ cruelest weapon — the clock itself. Time is ruthless under their spell. 🪄

10/26/2025

Day 3 of Hell Week is a cruel balancing act. Stability shattered. Spells cast. Balance bewitched. 🧙‍♀️ The witches have brewed instability — surges, wobbles, and no safe footing in sight. 🔮

Day 2: Draw of the Deep 🌊 — we dove headfirst into the challenge and came out stronger! Hell Week isn’t for the faint of heart 💪 P.S. sock game crazyyyyyy 😉

10/25/2025

Gravity never plays fair, especially when witches are in charge. 🪄Day 2 of Hell Week and the Spell of Gravity has us in its grip — inclines that won’t quit, weights that feel possessed, and no way out but through. 🖤

The witches didn’t waste any time — Day 1 of Hell Week and Havoc’s Hex was unleashed. 🪄 The chaos swirled, the order shattered, and the Spell of Chaos tried to take us down. But you? Unstoppable. 🧡 Drop a 🕸️ if you made it out alive.

Stronger than cancer. Stronger every day. 💕

In honor of Breast Cancer Awareness Month, we’re celebrating Jean from OTF Altamonte Springs — a fighter, a survivor, and a true inspiration to our OTF family.

At 48, Jean was diagnosed with invasive breast cancer and underwent a mastectomy, chemo, and radiation. Determined not to let cancer define her, she refused to become a victim. Years later, she discovered Orangetheory and hasn’t looked back.

Now at 67, Jean works out 5-6 days a week, takes on every benchmark and challenge she can, and has crushed incredible milestones — from completing her first DriTri Sprint to winning her studio’s Transformation Challenge to finishing the Ultra 31.1 Marathon with 47.89 miles. ​

"I’m not a victim to cancer — Orangetheory Fitness is my therapy every day." 🧡 Jean, your story reminds us of the power of resilience, community, and showing up for yourself — at any age, in any season of life.
