Voluntary activities is a defined item.

The two basic things to know are that any activities must be initiated and requested by the player, and coaches cannot be present at all (even if a player asks a coach to rebound for them).

Basically, this permits voluntary weights and conditioning run by the strength staff. A decision on summer access won't be made until later this week, probably. It seems unlikely that summer access will start before July 1 for basketball, if at all. Football will likely forego summer access, and just start preseason a few weeks earlier.

That being said, the waiver for virtual non-physical activities was extended through June, so basketball and football coaches can still require eight hours of virtual film and team meetings.

As mentioned below, it's going to be up to schools how to manage bringing players back to campus and what they're allowed to do, if at all.
