I’m trying out for the soccer team this spring and I need some ways to practice and get in shape.

Hi! I want to try out for my high school’s soccer team this spring. There are three teams–the freshmen team, JV, and Varsity. Because of my age, I would have to make the JV team to be able to play. In other words, I’m not a freshman. I have played soccer for 6 years, so I do have experience. However, I am very out of shape right now and my ball skills aren’t too fabulous. They never have been. My fortes are speed and aggressiveness. I am currently in a league playing for my parish, so I will be fully in shape by November, when we end. What can I do, starting now, to become a better player AND prepare myself for Spring tryouts? Also, what can I do over the winter to stay in shape?
When I say "become a better soccer player," what I mean is, how can I improve my stamina, speed, and ball skills?

Thanks a bunch!

Does anyone have any ideas or tips for how to train/get in shape/stay in shape for tennis during the winter? I can’t actually play tennis due to snow and lack of indoor courts, but are there any workout routines that people know of?
Thanks!
There is no YMCA or indoor courts available- I live in a rural, poor, and very snowy area.

I am certainly interested in trying out for a local volleyball team in January. I have had a couple years previous experience, but I haven’t actually played in a long time. What are some things I can do to get in shape and prepared for volleyball to make the team? Thanks in advance for your help!
