Can you exercise outside during isolation?

[Fruitteatime]

I thought if you were self isolating then you wouldn't be allowed to leave your house. I just did the nhs symptom checker and it says you can still leave to do exercise. Can anyone explain why? Is it because everyone is staying 2m away from each other or perhaps because exercise helps your immune system?

I thought the same as you OP, that if you have symptoms you have to stay inside!

I suppose they're saying it's ok because you're staying 2m away from other people.

I think it would be better if people with symptoms just stayed inside personally!
