Which of the following is NOT a focus area of Pilates practice?

In Pilates practice, the primary emphasis is placed on developing core strength, improving muscle endurance, and enhancing spinal alignment and flexibility. Core strength is foundational in Pilates as it supports the body's stability and balance during exercises. Muscle endurance is also cultivated through controlled, repetitive movements that engage various muscle groups over time.

Spinal alignment and flexibility are vital focuses in Pilates, as the method promotes proper posture and movement efficiency, ensuring that the spine remains healthy and functional.

High-impact cardio training, however, is not a focus area of Pilates. Pilates workouts typically emphasize low-impact, controlled movements that enhance strength and flexibility without the sudden stress or jarring impact associated with high-impact cardio exercises. Thus, while Pilates can support cardiovascular health, it does not prioritize high-impact activities, making this the correct response.
