AFAA Certified Personal Trainer | Endurance Athlete | Lifestyle & Transformation Coach

Joselyn Kirstein is a dedicated fitness professional with a lifelong passion for movement, health, and helping others build confidence through fitness. With a background in Exercise Science and a minor in Wellness & Fitness, she brings both education and real-life experience to her coaching approach.

As a military spouse and mother of three, Joselyn understands firsthand the challenges of balancing life, health, and personal goals. After her second pregnancy, she found herself over 200 pounds—facing, for the first time, the reality of not recognizing herself and needing to rebuild both physically and mentally. Through consistent exercise, proper nutrition, and determination, she transformed her health and regained her strength in just over nine months.

That experience became the foundation of her coaching philosophy.

Since earning her AFAA Personal Training Certification in 2013, Joselyn has expanded her fitness journey into endurance sports, completing multiple half marathons and triathlons. Her accomplishments include finishing the Chattanooga Half Ironman and the Rocket City Marathon—each representing her commitment to growth, discipline, and stepping outside of her comfort zone.

She specializes in:

• Weight loss and body transformation

• Endurance training and race preparation

• Lifestyle-based fitness coaching

• Beginner-friendly program design

• Motivation and accountability coaching

Joselyn is known for her ability to connect with clients, meet them where they are, and help them build sustainable habits that last. Her coaching style is encouraging, adaptable, and rooted in the belief that every person is capable of more than they think.

Clients can expect supportive, engaging sessions that challenge them appropriately while building confidence, strength, and long-term consistency.

TRAINING PHILOSOPHY

Joselyn believes fitness should be something clients look forward to—not something they dread. Her approach focuses on creating a positive experience while delivering real, sustainable results.

Her coaching emphasizes:

• Creating enjoyable, engaging workouts that build consistency

• Tailoring every program to the individual’s goals and starting point

• Prioritizing proper form and safety at every stage

• Progressive programming that builds confidence and strength over time

• Encouragement, accountability, and long-term habit formation

She is passionate about helping clients step out of their comfort zones, build confidence, and realize that lasting change takes time, dedication, and support.

Her sessions are uplifting, personalized, and designed to help clients feel stronger—not just physically, but mentally and emotionally as well.
