Ever since we heard the news that Shannen Doherty’s breast cancer spread to her lymph nodes, we’ve been rooting for the actress with all our hearts.

And People let us know that she’s giving this fight everything she’s got. Literally the day after Doherty underwent chemo – which is known to make patients feel like they have a bad case of the flu – she went to the gym.

On the way there, Doherty posted this inspiring message on Instagram.

Of course, it didn’t end there. Just to ensure that you feel appropriately encouraged to get out of bed and SEIZE THE DAY, Doherty posted this video of herself moving and shaking in a fitness class.

We love that Doherty is still having fun and engaging in physical activity during what’s got to be a grueling treatment. We are so incredibly inspired.

Now, excuse us while we plan a full day of action-packed activities!
