• Represent the MRT brand professionally on and off the floor
• Contribute to gym growth through referrals, visibility, and quality coaching

Ideal Candidate

• Prior group fitness coaching experience (F45, OTF, CrossFit, Burn, etc.)
• Strong understanding of movement patterns, cueing, and injury prevention
• Certified in CPT, CF-L1, NASM, ACE, ISSA, or similar (or actively pursuing)
• High energy, dependable, and coachable
• Team-oriented with a growth mindset
