Personal trainers work directly with clients' bodies, creating significant injury liability. Even with waivers, a client who suffers a serious injury during training can sue you personally. An LLC protects your home, car, and personal savings from these claims while also providing the structure needed to rent gym space and hire employees. Saint Paul is home to ~22K businesses and has a population of 311K, making it a thriving market for personal trainers. Forming your LLC in MN provides personal asset protection and positions your personal trainers business for growth in the Saint Paul metro area.
