Essential components of an effective warm-up routine include dynamic stretching, mobility exercises, and light cardio. Warming up prepares the body for physical activity by increasing blood flow to muscles and enhancing joint flexibility. Moves like leg swings, arm circles, and bodyweight exercises activate the muscles used during the workout, preventing injuries. A well-structured warm-up typically lasts 5–10 minutes and gradually elevates the heart rate. Prioritizing this routine can improve performance and ensure a safer, more effective exercise session.
