This allows an athlete to work on agility and explosiveness. In limited action as a gadget player he showed his pure speed and explosiveness. His teams were known for their fast tempo and offensive explosiveness. Speed and explosiveness is obtained by rolling at faster paces, easier with lighter weights. He also cited concerns about his lack of explosiveness and pass-rush moves. Laver described Hoad's strengths of "power, volleying and explosiveness" as justification of his accolade. Conditioning improvements included emphasizing free weights over Nautilus machines, to improve explosiveness. Increasing silica levels increase the viscosity of the magma which means increased explosiveness. Long-distance runners use the exercise to develop explosiveness. The proportions of these components vary depending on the desired explosiveness of the water gel. Potential hazards with chlorine dioxide include health concerns, explosiveness and fire ignition. He's known for his explosiveness and work rate. The Volcanic Explosivity Index (VEI) is a relative measure of the explosiveness of volcanic eruptions. This, despite being an event with a relatively low rate of explosiveness. He has been described as having "the explosiveness of James Cagney".
