What is a Warm-Up's Primary Goal?
The goal is to prepare your body for the physical stresses to come by creating specific physiological changes:
1. Increased Core Temperature: A light aerobic activity (jogging, jumping jacks) increases blood flow. Warm muscles are more pliable and elastic, like a warm rubber band, reducing the risk of strains and tears.
2. Enhanced Blood Oxygenation: As your heart...
