That’s a very good question. But it’s also a very individual question.
The articel provides a good overview…
If you still have symptoms, also if it’s just a slight cough, you should not do any exercise!
If you don’t have any symptoms (and are not in quarantine) anymore you could start with some light walking and see how you feel.
But it’s recommended to wait at least a week, afer your symptoms went away, to start with exercise.
As covid-19 is different for every patient I would recommend that you see your primary care physician, before starting true training. This way you make sure that you don’t miss anything and are truly healthy.
Always listen to your body and stop, if you notice any symptoms.
If you are carefull, I think you will be back to normal activity soon!
all the best!
