Indoor group activities and exercise classes are not allowed to take place under Tier 3 rules. However, Madeline Diaz and fellow instructors believe that yoga classes should remain open, as it is a meditative practise rather than a physical exercise class. The petition has already received over 8,500 signatures. Madeline operates The Mill Studios in Halliwell business park, as well as sites in Preston and Chorley. The Bolton studio only opened in January this year but it was forced to close on March 16. The studio reopened in August until the start of the second lockdown in November. Since then it has remained closed.
