Semi-Private Strength Coach (Part-Time)

About Devilfish Athletics

Devilfish Athletics is a semi-private strength gym in Brooklyn focused on helping adults become stronger, move better, and feel more confident in their bodies.

Our members are primarily adults in their 40s and 50s. Many are new to strength training, returning after time away, managing chronic aches and pains, or looking for a sustainable approach to fitness that fits into a busy life.

Position Overview

We are seeking a part-time Semi-Private Strength Coach to lead semi-private training sessions, support member progress, and contribute to a welcoming, professional training environment.

Our coaching team is not responsible for sales, scheduling, or writing individualized training programs. Those systems are already in place, allowing you to focus on delivering exceptional coaching and building meaningful relationships with our members.

Because every member follows an individualized training program, preparation is essential. Coaches are expected to review each member's program before every session, understand the goals, progressions, and modifications for each individual, and arrive ready to deliver thoughtful, professional coaching. Session preparation is required! 

As coaches gain experience and become familiar with our members and coaching philosophy, they'll have opportunities to contribute feedback on member programming. We believe the coaches who work with members every day provide valuable insight into what's working, what isn't, and when adjustments may be needed.

Responsibilities

Coaching

  • Lead semi-private strength training sessions of up to five members

  • Prepare for every session in order to execute programming effectively 

  • Coach exercise technique, movement quality, and training execution

  • Provide modifications and progressions when needed and appropriate 

  • Create a positive, supportive, and focused training environment

  • Build strong relationships with members and help them stay engaged with their training

Member Support

  • Implement individualized training programs designed by our head coach

  • Help track member progress and communicate observations

  • Help members navigate setbacks, injuries, and life events that impact training

  • Contribute to a high-quality member experience

Facility Operations

  • Arrive prepared and on time for scheduled coaching hours

  • Maintain a clean, organized, and professional training floor

  • Follow facility procedures and safety standards

  • Assist with basic opening, closing, and operational tasks as needed

  • Current nationally recognized fitness certification (NSCA, ACSM, NASM, ACE, or equivalent)

  • Current CPR/AED certification

  • Experience with personal training, preferably in a professional setting

  • Strong communication and interpersonal skills

Preferred

  • Experience coaching beginners and general population clients

  • Experience in semi-private or small-group coaching environments

  • Familiarity with fundamental strength training movements and equipment 

  • Some experience modifying exercise for clients managing pain, injuries, or movement limitations

Hours & Compensation

  • Part-time position 

  • Approximately 10-15 coaching hours per week initially

  • Opportunities for additional hours

  • Compensation: starting at $25–45/hour with opportunities for increases as responsibilities and hours grow

Growth Opportunities

Devilfish Athletics is in a period of growth, and we are looking for someone who is excited to grow alongside the business.

While this position begins as a part-time coaching role, we anticipate opportunities for increased hours and responsibilities as membership expands. For the right person, there may be a pathway toward a larger coaching role and potentially full-time employment in the future.
