Volleyball, with a traditional volleyball or with a lighter object like a beach ball or balloon, is a perfect activity to have residents be active! Traditional volleyball is suited for warmer weather and for the outdoors. So, if the weather limits your activities to indoors, try volleyball with balloons! They float more gently and more slowly, and are drastically reduce the chance of being hurt or causing damage. Be cautious of keeping adequate social distancing measures during the activity however!
