Failure to conduct thorough pre-participation screenings with members puts the personal trainer at increased risk of being sued for ______.

Negligence in a professional context requires four elements - duty, breach, causation, and damages. A personal trainer has a duty to screen clients for health risks before exercise; failing to perform that screening constitutes a breach of that duty. If a client is then harmed by exercise that the screening would have flagged as contraindicated, the trainer is exposed to a negligence lawsuit.

Discrimination involves treating individuals differently based on protected characteristics such as race, gender, or disability - it is not related to the omission of health screening procedures.

Breach of contract arises from failing to fulfill specific terms agreed upon in a contract, which is legally distinct from the tort of negligence arising from a failure to meet a professional standard of care.

HIPAA violations relate specifically to the unauthorized disclosure of protected health information and are not triggered by the failure to conduct pre-participation screenings.
