A woman advertises to do home massage ( Yes, I know, but she claims she is a physiotherapist. ) It would/wouldn't break lockdown? It would/wouldn't help building strength?
Normal physiotherapy would ideally be extensive, frequent and prolonged following extensive loss of condition.
In isolation, there's no motivation to find some u tube video and wave arms around a bit, especially if it's doubtful it will be done correctly, or that it will do the slightest good.
If you can go out walking/swimming/running, results are measurable, and there is little likelihood of doing something so incorrectly that it's damaging, so there's an incentive to keep it up. A qualified physiotherapist would seem ideal, but oddly she seems only to offer massage. Any thoughts, please?
