You can't really take any shortcuts when you want to improve your vertical jump. That's why you need to get a clear understanding of creating a program with a variety of muscle-building exercises that vary both the muscles and they days on which you train for each muscle. Working the same muscle groups continuously or back to back will not work. Your muscles will not perform well for you, if you do not very the intensity and the variety that are used. You also need to rotate groups from day-to-day to allow them to repair themselves and grow stronger.
