From what I've heard, all the basketball coaches are on their way to Brazil. None stayed behind.
We'll try to get an answer to your question. But I am sure the new guys who aren't on the trip, have a strict schedule for them to be working out during this stretch while the rest of the team is in Brazil.
But realize that if not for this trip, this is a period where the coaches would not be allowed any coaching sessions, and minimal contact with the players anyway. So I don't think this is a problem.
