For many cancer survivors, the suggestion of “going to the gym” doesn’t exactly spark joy. After months or years of clinical appointments, scans, and treatments, spending free time in another body-focused environment can be intimidating.
Marian McDonald shared that hesitation. In addition to recovering from breast cancer treatment, Marian was also navigating the complexities of living with multiple sclerosis. But her story is proof that with the right support, you can do hard things—and you might even find a new calling along the way.
Finding the Right Time to Heal
Marian’s journey began in July 2022 when she was diagnosed with breast cancer. Her path to recovery was long and grueling, involving a double mastectomy, reconstruction, chemotherapy, and eventually a hysterectomy. Because of MS, her body required a slower, more intentional pace for healing from cancer treatment.
She first heard about Survivor Fitness in late 2023, but she wasn’t ready yet. She still had surgeries on the calendar and needed time to process the weight of her diagnosis. It wasn’t until late 2025 that the opportunity resurfaced in what she calls “perfect timing.” In mid-December, she took the leap and began her intake process.
Overcoming the “Gym Hurdle” and Other Health Conditions
Marian didn’t hide her feelings when she met her trainer, Bree, at Tri-Fit Athletic Club in Murfreesboro. “I told her that I hated the gym,” Marian recalls telling her during their first meeting. “I’m sure that made a great impression.”
Beyond her mental hesitation, Marian’s MS caused weakness on one side of her body, creating constant balance issues. The reconstruction surgery had left her feeling physically limited and fearful that she might hurt herself if she pushed too hard.
However, Bree met Marian exactly where she was. She pushed her gently, encouraged her constantly, and taught Marian about a strength she had hidden away.
“There were things Bree said we were going to do, and I replied, ‘Yeah right,’ Marian remembers. “But I always said I would try, and usually that was all it took. I did hard things—things I never imagined I could.”
Finding a Community for New Hard Things
As the weeks passed, the woman who “hated the gym” found herself looking forward to her sessions. She began combining her Survivor Fitness exercises with her physical therapy to build a foundation of strength that helped combat fatigue and muscle weakness.
She also found vital support through her nutrition coach. Together, they tackled the difficult battle of weight gain caused by hormone blockers and medications for depression and anxiety. For Marian, having these tools made her feel prepared for the battle rather than overwhelmed by it.
Her experiences also gave her a new sense of purpose.
“After years of fighting to live, fighting to be a better version of me was a welcome change,” she shared.
Her nutrition coach even encouraged her to consider going back to school to become a Registered Dietitian specializing in oncology nutrition. It’s a big goal, but Marian isn’t backing down. “It’s a hard thing, but I can do it. I just have to find a way.”
A Message for Other Survivors
Marian’s journey is a reminder that self-confidence doesn’t always return the moment treatment ends. It is something that must be rebuilt, one step at a time. She encourages other survivors to talk to their oncologists, get a referral, and accept the opportunities that come their way.
“Becoming physically stronger was a huge accomplishment, but learning that I can do hard things was a great confidence builder,” she explained.
Marian’s trainer and coaches have become a permanent part of her circle. She stepped into the program looking for health, and she walked away with a support system, a new career path, and the knowledge that she is capable of more than she ever imagined.
