Also doing sport specific drills. "Train how you play". Google "training drills" for whatever sports you want to focus on, and maybe spend one day a week doing drills, or add 1-2 of them to the end of every workout. By repeating movements in an explosive way one usually becomes better at these movements. Its hard to focus on "being explosive" while playing and sometimes I find a person simply is not using full potential in game. Repetition can help with this.
