My DD plays 12U for a good sized organization with numerous teams from 10U to 18U. We have never practiced with other age groups. Is practicing with different ages groups or teams of same age a common thing? DD has been playing travel for a while and we've never done it. During the peak of covid, some of the older girls ran zoom speed and agility classes for our players but we've never mixed up ages in a practice. I could see the younger players really liking to practice with the older players. Wonder if older players truly enjoy having the younger players around while they're trying to workout.
