Why We Built PEAKFIT.
In 2020, PEAKFIT. founder Katja Raab was diagnosed with breast cancer. She chose a double mastectomy — and then made a decision that changed everything: instead of following the conventional path alone, she put her faith in the power of fitness and nutrition to rebuild her body and her life.
That experience became the foundation of this studio. Not a gym built on vanity metrics and loud music, but a quiet, private space where real people do the hard, meaningful work of getting stronger — physically, mentally, and emotionally.
Katja’s son Alexander, a certified personal trainer with a degree in exercise and health science from Florida Atlantic University, co-founded the studio and leads the training team alongside Franklin Pierce, a corrective exercise and mobility specialist.
Together, they built PEAKFIT. around one belief: your body is capable of more than you think, and it’s never too late to prove it.

Private 1-1 Training
No shared equipment. No distractions. Every session is just you and your trainer in your own private station, following a program designed specifically for your body. Build strength, improve mobility, prevent injury — at your pace.
Small-Group Personal Training
Our Small Group Personal Training program brings together like-minded individuals, delivering expert coaching and personalized programming in a fun, results-driven environment
Nutrition Counseling
Your trainer can’t out-train a bad diet, and neither can you. Our coaches use the PEAKFIT. 360 Workbook to build an eating strategy around your real life — not a fad diet you’ll quit in two weeks.
Corrective Exercise & Mobility
Have a bad knee? Stiff shoulder? Chronic back pain? Our corrective exercise specialist doesn’t work around your limitations — he works on them. Move better first. Get stronger second.
Juice & Smoothie Bar
Fresh-blended smoothies and cold-pressed juices made with whole ingredients. The perfect post-workout recovery fuel — or just a healthy reason to stop by. Open to everyone, no membership required.
Infrared Sauna & Red Light Therapy
Our full-spectrum infrared sauna penetrates deep into muscle tissue to reduce inflammation, ease joint pain, improve circulation, and speed recovery. Pair it with red light therapy for cellular-level repair. It’s not a luxury — it’s how your body heals.
InBody Body Composition Analysis
Step on our medical-grade InBody scanner and see the truth in 60 seconds: muscle mass, body fat, hydration, visceral fat. No guessing. No hoping. Just data that shows exactly where you are and tracks where you’re going.
This is not a Gym!
PEAKFIT. Studio is a private strength and wellness studio in Arden, NC, built for adults who are done with crowded gyms, generic programs, and guessing whether anything is actually working. Here, you train in your own private station with a certified personal trainer who knows your name, your body, and your goals. We combine one-on-one strength training with personalized nutrition coaching, medical-grade body composition tracking, infrared sauna recovery, and a fresh juice bar — all under one roof. Whether you’re 45 or 75, recovering from surgery or training for the next chapter of your life, we meet you exactly where you are and build from there.
This is personal training the way it should be: private, expert, and designed to change your life not just your afternoon.
