Hi Christina! I'm not a gym person either and prefer the outdoors (swim, hike, cycling etc)
I sometimes do free online yoga/workouts, but those can get boring and it's not always easy to make the time for when you've got housework and kids running around in the background.
However, once in a while I need to change up my fitness routine and will do indoor stuff that pushes me in a different way.
I take a look at the different in-studio options I have in my neighborhood or workplace that are easy to access. Then I check out if they have a sale or promotion. Typically,I'll sign up for a 10-class pass to see if it's something to give it a good try.
If it's something I love, I'll stick with it or at least incorporate it into my regular routine. If not, I drop it. At the end of the day, for me, it needs to be something I love doing...or push myself to keep at it until I love it!
Best of luck, Christina...I'm sure you'll get there! Take those fitness instructor muscle memories you still have in your bones and take those baby steps towards change...one class/session at a time...you got this! Mary:)
