Which of these is NOT one of the Six Sins in the TRX format?

The correct answer is that "Hitching" is not one of the Six Sins in the TRX format. The Six Sins are common movement faults that instructors look for during TRX training to ensure proper form and effective training outcomes.

Hitching refers to an undesirable movement pattern where an individual may use their upper body or legs inappropriately to lift themselves during a suspension training exercise. While it is a movement fault that can appear in various fitness contexts, it's not categorized as one of the primary Six Sins in the TRX framework.

The Six Sins—such as Slacking, Scraping, and Twisting—highlight specific ways that form can break down, leading to ineffective workouts or increased injury risk. These concepts are vital in helping instructors and participants maintain integrity in their movements and achieve optimal results from their training sessions. Understanding the official terminology and categorization helps ensure that participants focus on correct form and mechanics while using the TRX system.
