Chris: How can a soccer goalkeeper keep practicing during the cold winter seasons?
Soccer seasons over for the Fall but I really want some advice to keep on my game and keep getting better in goal. Indoor soccer is out of the question because their season has already started. Also, how can I practice on my own during season outside.
