COVID-19 UPDATE

As of May 29, 2021 fully vaccinated (completed vaccinations and waited the full two-week period) clients may remove their masks while working out. Masks are required at all other times while inside the facility.  Proof of your vaccination may be required.

We still require masks for anyone not working out, even if vaccinated.  Our coaches will be required to wear masks, unless vaccinated coaches are working with other vaccinated clients.

As of right now, Health Forms are no longer required.  However, if you are feeling unwell, please stay home! 

Action Athletics wants to ensure that everyone in our community is comfortable with these changes, so we will continue to open back up slowly and safely.  We thank everyone for your support and cooperation as we are adapting back to a mask-less and fully-functioning world!

COVID policies that are still applicable:

• Sanitization upon entry to the facility.
• Continued cleaning of high touch areas.
• No food or beverages available for purchase.

Local stars like Casey Rothschild, Alex Goodwin, Conner Claffey,  Paulina Sterpe, and Josh Shriber as well as All-Star competitors like Jon "The Giant" Alexis, Jesse "Flex" Labreck, Allyssa Beird, and more helped build us into one of the country's finest obstacle training facilities.
