Happy 250th Birthday to America! 🇺🇸
🇺🇸Today, as we gather under the stars ✨ and stripes for parades, backyard barbecues 🌭 , and fireworks 🧨 , let’s take a moment to celebrate the rich history, the vibrant diversity, and the indomitable spirit of this great nation.
From sea to shining sea, America has always been a beacon of hope, opportunity, and liberty. It is a country that continually grows, learns, and strives to live up to its founding ideals of a “more perfect union”.
Whether you are celebrating in your hometown or enjoying a getaway, we hope your holiday is filled with joy, laughter, and quality time with loved ones.
As the fireworks light up the sky, let us also remember to express our gratitude to the brave service members, veterans, and homeland heroes whose sacrifices make our everyday freedoms possible.❤️🤍💙

Our Reborn class sadly lost one of our athletes a couple weeks ago, so on Friday morning we put on her favorite color and did a workout in her honor.
Levon was one of our original Reborn members, and she always came in with a happy attitude, willing to try anything. (She even kept trying to do bear crawls, even after we told her not to because they made her light headed and almost pass out.) She was our first Reborn athlete to actually run instead of walk during a 100 meter run, which meant from then on out, we were all out of excuses not to run, too.
Not only was Levon an amazing athlete with a can-do attitude, but she was a great friend. She wanted to make sure everyone felt needed and loved. She brought in birthday cards for everyone to sign on our special day. She took time after class to sit and visit while we were all wiped out from the workout. And she always came in with a bright, happy smile that could totally make your day.
We love you and already miss you, Levon!
