Well Whitty and Valance were very positive about exercise during this pandemic on a select committee this afternoon but, as they had to point out numerous times, they don't create policy, they just inform those who go on to create policy.
If everyone did enough exercise then the pressure on the NHS would be quite significantly less, although anyone doing Audax is almost certainly doing more than enough exercise not to be lumped in the 'unhealthy' bucket so they're not really going to be the target audience for "more exercise".
