When a plaintiff fully understands the risks associated with an activity or situation and voluntarily chooses to engage in it anyway, the defendant may have a valid defense against a negligence claim. This concept is particularly relevant in environments such as CrossFit, where participants are often made aware of the potential dangers involved in high-intensity workouts and physical challenges. By acknowledging that they understand these risks, participants may limit the liability of the coach or facility should an injury occur.

In practical terms, this defense implies that the plaintiff cannot reasonably claim that they did not foresee the potential for injury when they have been adequately informed about the dangers involved. Understanding and accepting these risks means they had a choice and cannot place full blame on the provider—a key consideration in negligence lawsuits.
