As many of you probably already know, Governor Newsome has scaled back his plans on how he will reopen California and has even taken a step backwards in several counties. Most of these did not affect Alameda County as we were not allowed to open the things he has ordered to close again. It has, unfortunately, had a great effect on us in terms of when gyms will be allowed to open by drastically slowing down the process to get to those sectors in the community open for business.
