Hello, I would like to ask for help with translating one word or maybe a collocation: "Every summer I go to a basketball/music/yoga ???." In Czech we call it "concentration" and it means the following: you normally play basketball / a musical instrument / do yoga for example once/twice a week throughout the year but in summer (or any time) you go to a place with other basketball players/violinists/people who do yoga to spend the whole week concentrating on this activity. It helps you to improve in that particular activity or you go there to get ready for a competition/match. Also sportsmen go to ??? before important sports events, for example Olympic Games. Could I use the word "camp" in this case? I hope I explained it enough. Thank you very much for help.
