Millions will gather with family or friends on Thursday to celebrate Thanksgiving, but some may want to work hard or exercise in the hours before the holiday.

The best way to make sure you can lift some weights for Turkey Day is to find out when your gym will be open, or if it will be open at all.

Some gyms may be completely closed, while others may offer members the opportunity to work out at adjusted times. Many grocery stores, retail stores, restaurant chains and even pharmacies tend to close or implement limited hours in honor of Thanksgiving.

Here’s what you need to know about major gym chains like Planet Fitness, LA Fitness, and YMCA and whether or not they’ll be open on Thanksgiving this year.
