Job Title

Personal Trainer & Small Group Strength Coach – RockBox Fitness Summerville

About the Role

Are you an ambitious, forward-thinking Personal Trainer looking for a premium space to build a high-income training business? RockBox Fitness Summerville is launching a dedicated initiative to maximize our studio space during non-class hours. We are seeking an entrepreneurial, results-driven Personal Trainer & Small Group Strength Coach to build and lead our private and semi-private functional strength program.

The modern fitness landscape has evolved. We aren't just looking for someone to count reps; we need a coach who understands the intersection of strength training, metabolic health, and nutrition. With the massive rise of GLP-1 weight‑loss medications, our clients need an expert who knows how to pair these therapies with targeted resistance training to preserve lean muscle mass, optimize metabolic rate, and drive long-term lifestyle success.

While you will have direct access to our active member base to source clients, the expectation is that you are a true business builder hungry to market your skills, convert leads, and aggressively grow your own book of business within our facility.

Note: While RockBox is famous for boxing and kickboxing, the primary focus of this specific role is dedicated functional fitness, nutrition coaching, and strength training—no boxing required for these sessions.

Key Responsibilities

• Build Your Book of Business: Proactively market, sell, and retain clients for 1-on-1 personal training and small group (semi-private) strength sessions during off-peak hours.
• Metabolic & GLP-1 Coaching: Design custom training programs tailored specifically for clients navigating weight-loss journeys, including those utilizing GLP-1 medications. Focus heavily on lean muscle preservation, bone density, and structural strength.
• Nutrition Guidance: Provide actionable nutrition coaching, tracking protein targets, caloric intake, and hydration to support metabolic health and body composition goals.
• Leverage the Community: Actively engage with existing RockBox members on the floor and via digital outreach to introduce them to our strength and nutrition programs.
• Track Client Results: Conduct initial fitness/metabolic assessments, set precise goals, track biometric data, and adjust programming to ensure clients hit tangible targets.
• Versatility (The Plus Factor): Step into the ring to run or sub our signature large-group boxing/kickboxing fitness classes from time to time when needed.

What We Are Looking For

• Proven Client Acquisition: A track record of successfully building, managing, and retaining a private personal training or small-group client book of business.
• The Entrepreneurial Mindset: You want to hunt for leads, close training packages, and directly control your earning potential.
• Certified Experts: A current, nationally recognized Personal Training certification (NASM, ACE, ACSM, ISSA, etc.).
• Nutrition Credentials: A verified nutrition certification (Precision Nutrition, NASM-CNC, or similar) is highly preferred.
• Modern Health Literacy: A strong understanding of modern metabolic health and the physiological impact of GLP-1 medications (e.g., managing muscle loss risks, navigating severe caloric deficits, and maintaining training energy).
• Strength Specialists: Deep knowledge of exercise mechanics, hypertrophy, and functional training using kettlebells, dumbbells, barbells, and TRX straps.
• Boxing/Kickboxing Skills (Nice-to-Have): Experience coaching striking is a bonus for subbing regular classes, but your main passion must be functional strength and wellness.

Benefits & Perks

• Uncapped Earning Potential: We offer a high-upside, hybrid compensation structure built for growth.
• Premium Studio Access: Use a fully equipped, top-tier boutique facility during off-peak hours to run your private sessions.
• Built-in Lead Pool: Direct access to hundreds of fitness-focused local members who already know and love the RockBox brand.
• The Perks: Free studio workouts, official gear, and a highly supportive, growth-oriented team culture.
