Kendra's goal of being able to bend over and touch her toes after completing 12 months of yoga training is primarily a performance-related goal. This type of goal focuses on improving a specific skill or physical ability, which in this case is flexibility.
While it may indirectly contribute to mental health benefits associated with yoga practice, it is not primarily categorized as a mental health goal. Additionally, since the goal is set for 12 months, it is not considered a short-term goal; rather, it's a long-term goal.
Therefore, the most accurate description of Kendra's goal is that it is a performance-related goal.
