I am a freshmen in high school, I'm about 5'3'' and 110 lbs., I have never been a fast sprinter, yet my endurance is good because I have been playing soccer. I can run a sub 6 min. mile easily, however, I want to be quicker and a better sprinter because baseball is my favorite sport and I need to have fast times. What would you recomend, workout wise, I have access to the local Lifetime(Health club).
