ex.science fitness goal

For my fitness, the goal I want to reach is to keep getting higher throughout the year on my beep test score.I usually get around 11-12. My goal is to reach 14 by the end of this semester. I want to keep getting better and improving my score each time we do the beep test and at the end of the semester i want to achieve my goal. A work out that will help me with this, will definitely be running/ jogging regularly and working on my stamina by doing running long distance. An app that I could use to create a routine for me is 'bleep fitness test' where it lets me do the beep test and calculates my vo2 level which is great!
