Fort Worth Fit Body Boot Camp Fort Worth, TX

Pay: $14.00–$16.00 per hour

Job Type:

• Part-time
• Paid Internship

Expected Hours:

• Approximately 9–15 hours per week

Availability Needed

Our immediate need is within our growing Fit Body Forever program, which serves adults primarily 60+.

We are looking for an intern with consistent availability during some of the following daytime hours:

• Monday, Wednesday & Friday: between 9:00 a.m.–1:00 p.m.
• Tuesday: between 10:00 a.m.–11:45 a.m.

You do not need to be available for every hour listed. We're looking for someone who can consistently work within some of these timeframes.

As you progress through our internship and coaching development program, you will also be cross-trained to coach our Fit Body Boot Camp program. Additional early-morning and evening coaching opportunities may become available as you develop.

About the Internship

At Fort Worth Fit Body Boot Camp, we believe fitness changes lives, not just physically, but mentally and emotionally.

Our Coach Internship Program is designed to develop well-rounded fitness professionals through hands-on coaching, mentorship, leadership training, and real-world experience.

You'll begin your coaching development primarily within our Fit Body Forever program, an ever-growing program designed to help adults 60+ build strength, improve mobility and balance, maintain independence, and age with confidence.

As your skills, confidence, and coaching ability grow, we'll cross-train you within our Fit Body Boot Camp program, giving you experience coaching different ages, abilities, fitness levels, and training styles.

Our goal isn't simply to teach you how to run a workout. We want to develop you into a confident, knowledgeable coach who can connect with people and make a meaningful difference in their lives.

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, dependability, and a genuine passion for helping others matter even more.

What You'll Learn

During your internship, you'll progressively learn how to:

• Coach small-group strength and functional fitness sessions
• Work with adults 60+ through our Fit Body Forever program
• Help members improve strength, mobility, balance, and confidence
• Demonstrate and modify exercises for different abilities and fitness levels
• Coach safe, engaging, and encouraging training sessions
• Build genuine relationships with members
• Improve your communication and leadership skills
• Motivate and hold clients accountable
• Understand client retention and the member experience
• Coach our signature 45-minute Fit Body Forever and our 30-minute Fit Body Boot Camp workouts
• Work with a broader range of ages and fitness levels

You'll start by learning the Fit Body Forever side of our business and, as you progress, be cross-trained into Fit Body Boot Camp.

By the end of the internship, our goal is for you to have experience coaching both programs and the skills needed to continue growing as a fitness professional.

• Is eager to learn and grow
• Works well as part of a team
• Enjoys building relationships
