Warming up for any sport should be active and dynamic so that the body builds core heat which helps warm the muscles and the connective tissue, increases synovial fluid (for joints), nerve conduction (coordination and balance), and oxygen exchange. Heated movements (mostly full range of motion) keeps the elastic spring that helps add power to a swing.
