  • “Thank you, Big C, for bringing La Blast to the early mornings! I did the Hustle, The Tush Push, and the Electric Slide all before 6:30 am! What a great start to my weekend.”

  • “Karen James is what makes me come to the gym every morning. She's so encouraging, so helpful. She's quite simply the best! She's what makes the Big C so good.”
