Will this workout plan build my physical fitness?

I'm 13 years old and I play on a competitive soccer team in W.A.G.S. My coach said that our team's weakness is our endurance, and I'd like to build my fitness over the summer. I've decided to start off by running 20 minutes on an eliptical machine at about 60 RPMs, for about a week. Next week, I'll go for 30 minutes. I'll gradually work my way up to an hour. Do you think this will help build my endurance?Will this workout plan build my physical fitness?Sure it will help, but I would recommend mixing in some treadmill running and biking. Also work on your basic strength would help.



How about the hundred push ups plan too?
