We had Inchworms in our Reborn WOD today, with the option to do partial Wall Walks, if you can. We warmed up real well, then practiced getting on the wall. I heard:

“The first time I did Wall Walks was in the Open. But I could only get my feet on the wall. Now, I can lift my hands.”

“I’ve never been able to do that before!”

It’s so fun to see the progress our athletes make because they’re showing up and putting in the work. We are all starting at different points on the fitness and mobility scale, and we progress at different speeds. But the point is, we are progressing!

We’re getting fitter. We’re getting stronger. And we’re having so much fun!

Memorial Day is a time to pause in gratitude and remember the brave men and women who gave their lives in service to our country. Their courage, sacrifice, and unwavering commitment created freedoms and opportunities that continue to shape our lives every day.

Today, we honor those heroes. May we live with gratitude, lead with kindness, and never forget the cost of the freedoms we enjoy. ❤️🤍💙

Wishing everyone a meaningful Memorial Day filled with remembrance, reflection, and thanks. 🇺🇸
