About Us

At Fort Worth Fit Body Boot Camp, we believe fitness changes lives, not just physically, but mentally and emotionally. We're a high-energy, relationship-focused coaching team committed to helping people become the strongest version of themselves.

We're looking for someone who wants more than just a job. Our Coach Internship Program is designed to mentor and develop future fitness professionals through hands-on coaching, leadership training, and personal growth.

Whether you're studying exercise science, recently certified, or looking to launch a career in fitness, we'll give you the tools, mentorship, and real-world experience to succeed.

No Certification? No Problem.

Don't let that stop you from applying.

We're looking for the right person, not just the right résumé. If you're passionate about fitness, love helping people, and are eager to learn, we'll provide the training and mentorship you need. For the right candidate, we'll even pay for your nationally recognized personal training certification.

Experience is helpful, but character, coachability, and a genuine passion for helping others matter even more.

What You'll Learn

As a Coach Intern, you'll receive hands-on training to:

• Coach our signature 30-minute small-group HIRT workouts
• Lead safe, engaging, high-energy training sessions
• Build genuine relationships with members
• Demonstrate and modify exercises for all fitness levels
• Improve communication and leadership skills
• Learn client motivation, accountability, and retention
• Understand the business side of the fitness industry

You'll also have the opportunity to learn from nationally recognized fitness leaders including Bryce & Barrett Henson, Darrylynn Silva-Costa, George Vidosh, and Robert Linkul.

We're Looking For Someone Who

• Brings positive, contagious energy
• Genuinely loves helping people succeed
• Is coachable and eager to grow
• Works well as part of a team
• Enjoys building relationships
• Is dependable, professional, and self-motivated
• Believes fitness is about changing lives, not just counting reps

If you're simply looking for a job to clock in and clock out, this probably isn't the right fit.

If you're looking for mentorship, personal growth, and the opportunity to become an exceptional coach, we'd love to meet you.
