The NBA announced last week that it would allow teams in markets with relaxed stay-at-home orders to start using practice facilities on May 8.
The restrictions regarding workouts are numerous. No group workouts are allowed, and head coaches and front-row assistants are prohibited from participating. There are also stringent health protocols in place including to temperature checks and cardiac screenings, how to properly sanitize basketballs and the floor, and mandatory use of face masks except when engaged in physical activity.
The basketball portions of these workouts appear to be limited to shooting around, working out with player development coaches, and potentially receiving treatment.
