How powerful does?

Answer 1

power = speed x strength So to increase your power you must: 1) increase the speed at which you can perform the movement 2) or increase the amount of weight you can perform the movement with AND the speed at which you can perform the movement Generally speaking one will see improvements with any improvment in speed OR strength. Once you reach professional level competition with highly trained atheles it becomes a little more complex than simply increasing one of these variables.
