Hosting a socially-distanced stretching session in a large open space would be a great group activity for residents who've been help up in their rooms and miss seeing others! Stretching is an stationary activity too, allowing significantly improving safety as residents get their exercise in. A stretching session or class can be short or long as well, as time permits. Consider switching up the mood of sessions as well, one being relaxing with low light and gentle music. Another could be brighter, with more active music playing to get resident's alert and energized! Proper precautions must be taken of course, like masks, proper ventilation and diligent disinfecting of materials.
