Dynamic stretching is primarily utilized in dynamic warm-ups because it involves active movements that enhance muscle elasticity and prepare the body for physical activity. This type of stretching mimics the motions of the exercise about to be performed, helping to increase blood flow, elevate heart rate, and improve overall range of motion. During dynamic stretching, movements are performed in a controlled manner, allowing muscles to warm up gradually while improving functional flexibility.

In contrast, static stretching involves holding a stretch at a fixed position, which is not ideal for warm-ups as it can lead to a temporary decrease in muscle strength and power when performed prior to activity. Proprioceptive neuromuscular facilitation (PNF) is a more advanced stretching technique that combines stretching and contracting of the muscle, typically used in rehabilitation or advanced training settings rather than in warm-ups. Ballistic stretching employs momentum to force a body part beyond its normal range of motion, which can increase the risk of injury when done without proper preparation. Therefore, dynamic stretching is the most appropriate choice for warm-up routines as it effectively prepares the muscles and joints for the demands of the workout.
