Provide hands-on coaching during sessions to teach, demonstrate, and correct exercise technique, ensuring clients perform exercises safely, efficiently, and with proper form to reduce injury risk and maximize outcomes.
Monitor and document client progress using objective metrics (strength metrics, body composition, endurance tests, performance benchmarks) and subjective metrics (RPE, sleep, readiness), and update programs accordingly to sustain progression.
Deliver motivational coaching and behavior change strategies, applying client-specific communication techniques, goal refinement, habit formation, and accountability systems to improve adherence and retention.
Create and implement corrective exercise protocols for clients presenting muscular imbalances, mobility restrictions, or postural deviations, collaborating with physical therapists when appropriate and referring out when red flags are identified.

Onboard new clients with clear expectations, intake forms, waivers, goal plans, and scheduling protocols; manage trial sessions and conversion of leads into long-term clients through consultative sales conversations.
Use digital platforms and training software (e.g., Trainerize, TrueCoach, Mindbody, WellnessLiving) to deliver remote programs, log workouts, communicate, and maintain accurate training notes and client calendars.
Build and maintain professional relationships with internal teams (front desk, management, recovery staff) and external partners (physical therapists, sports teams) to support client outcomes and cross-referrals.
Maintain facility safety and cleanliness, ensure equipment is set up correctly for sessions, perform basic equipment checks, and report or escalate maintenance issues according to facility procedures.

Create progressive and periodized plans for special populations (youth, prenatal/postnatal, older adults, clients with chronic conditions such as diabetes or hypertension), ensuring programming follows current clinical guidelines and scope limits.
Drive client retention initiatives by scheduling follow-ups, running progress reviews, introducing new programming techniques, and implementing re-engagement strategies for inactive clients.
Deliver educational workshops or seminars on fitness topics (strength training basics, mobility, injury prevention, recovery strategies) to members and staff to elevate client knowledge and facility programming value.
Maintain current professional certifications (CPT, CPR/AED, specialty certifications like corrective exercise or sports performance) and complete required continuing education to ensure best-practice application.
Achieve individual revenue and retention targets by offering packages, retail products, nutrition add-ons, and upselling appropriate services using consultative, client-first sales approaches.
Document all client interactions, program changes, and incident reports accurately and promptly within the facility’s CRM or training software to ensure continuity of care and legal compliance.
