I'm in between but I think unless your dc is unsuited to Extracurricular activities you are doing then a disservice to do nothing.
Mine both do swimming (rookie lifeguard for the eldest) and cubs/scouts. One does violin and they both do piano. I think music is good for brain development regardless of achievement and it lays down musical ability so they can pick it up as adults. Otherwise it's really hard to learn when older.
Then the eldest is really into football. We "only" do practice + weekend matches and not a separate training sessions like a lot of teams round here where football is a 3x week activity.
He's just started a new school which is big on extracurricular so he also does rugby, basketball, water polo and choir!!! That's mostly in school time. Apart from Saturday rugby and midweek evening water polo.
I think its good for them to be able to do the activities they want to do. Some activities do need to be forced a little (I don't know many willing musicians) for their own good. It's not about university applications. Its about enjoyment mainly.
I have a demanding job but dh and I split it between us to take dc to their different activities.
