What is NOT recommended when preparing to exercise?

Static stretching is not recommended when preparing to exercise because it can reduce muscle strength and performance if performed when muscles are cold and not adequately warmed up. This type of stretching involves holding a position to elongate the muscle, which may lead to temporary muscle relaxation and decreased muscle readiness for the demands of vigorous activity.

In contrast, gradually increasing intensity helps prepare the body for the physical demands of exercise by warming up the muscles and increasing blood flow. Similarly, sport-specific warm-ups engage the muscles that will be primarily used in the activity and enhance neural pathways related to those movements. Walking at a slow pace serves to gradually elevate the heart rate and warm up the legs, making it a beneficial component of a pre-exercise routine. Therefore, while the other options enhance readiness for exercise, static stretching is best reserved for after the workout to aid in flexibility and recovery.
