Self-isolation helps stop coronavirus spreading
Do not leave your home if you have symptoms of coronavirus (COVID-19) or live with someone who does.
This is called self-isolation.
If you are self-isolating, you must:
not leave your home for any reason, other than to exercise once a day – but stay at least 2 metres (3 steps) away from other people
Not to derail but this is directly pasted from the NHS website, you CAN leave your home to exercise as long as you physically distance yourself from other people
