For sure in the US there is a traditional method of training for soccer, which resembles playing games, and running cross country style fitness sessions. I have seen this recommended at nearly 15 different colleges, male and female programs.
I will post some “speed” sessions from several schools. This will be good for a laugh. the sad part is, one school who does (or did ) this, is probably the most successful team of any sport. More comments to be posted later…
