Certified Fitness Instructor and Group Exercise Leader
Domstad Health & Fitness
Dear Hiring Team,
I am writing to express my enthusiastic interest in the Fitness Instructor position at Domstad Health & Fitness. With formal vocational qualifications in Sport en Bewegen and hands-on experience delivering gym floor instruction and fitness evaluations in Utrecht, I am eager to help your members pursue their exercise goals safely and consistently.
In my current role as a Junior Fitness Instructor at PolderFit Health Club, I conduct comprehensive gym inductions and baseline fitness assessments for new members, translating their individual targets into structured introductory training routines. I also supervise floor activities to coach correct lifting mechanics and lead bi-weekly small-group circuit training and core conditioning sessions for cohorts of up to 12 participants. These duties have strengthened my ability to communicate clear exercise cues, adjust movements for diverse physical baselines, and maintain an orderly, welcoming gym environment.
Previously, during my internship at Kromme Rijn Sports Center, I assisted senior trainers with movement screenings and dynamic warm-ups while demonstrating proper resistance machine and free-weight execution for beginner members. Additionally, I supported staff in coordinating a 30-day community mobility challenge completed by over 60 active club members. Combined with my Fitness Trainer A qualification from NL Actief, this foundation enables me to guide members through foundational movement patterns and encourage steady adherence from day one.
Domstad Health & Fitness provides a community-oriented approach to daily physical activity that closely aligns with my instructional practice. I would welcome the opportunity to discuss how my practical assessment skills, circuit training experience, and commitment to member safety can contribute to your fitness team. Thank you for your time and consideration.
Sincerely,
Sanne van Leeuwen
