Hello, Consider this example, please. "Some months ago I went on a trip to one of Austria's ski resorts. I had a lot of skiing practice there and really enjoyed my stay there. Since that time I've gone skiing every weekend. I'm really keen on this kind of sport now." On the one hand, the Present Perfect Progressive ("I've been skiing") seems more likely here. On the other hand, "every weekend" requires a simple tense, not a progressive one. Is it correct to say "I've gone skiing every weekend" and is it also correct to say "I've been going skiing every weekend"? Note that we're dealing with an ongoing action here (= I've kept on going skiing since then). A similar example: "Since my last birthday I've played golf twice a week". Is "I've been playing golf twice a week" correct or not? Thank you!
