I find chatting to my clients is a hugely enjoyable part of my work in clinic. You can still engage with your community in the same way but just online. On Instagram commenting with at least 4 words will have a positive impact on the reach of a post so if your client has a business of their own, leave longer comments on their posts. Get your highlights set up on your Instagram page with things like the most common stretches you give out in practice. Then instead of printing out exercises, you can refer people to your page to check the demo out and gain a follower at the same time!
However you spend your time in self-isolation as a business owner, you can make the most of this time to get ahead on those little tasks that are always clogging up your to do list. But just remember to make the most of every moment. Once we are all back to our usual working lives and routines, we will miss some of the stillness and solitude this crazy time has brought.
