We know you like to skip the active break. 👀 But what if we told you those 30 seconds could help you get better results? Active breaks give you a chance to recover while keeping your body moving and your heart rate up. That means you can make the most of all 30 minutes, burn more calories, and maximize your workout.

So next time your 9Round Trainer pushes you through that active break, just remember: they’re doing you a favor. 😉

What are you grateful for? We’ll go first: YOU. 🥊 Happy World Gratitude Day,  !

We had a blast at Training Camp this week with some of our Canada crew! 🥊 They put our core value of Kaizen—continuous improvement—into action by learning more about the brand, building their business skills, and mastering the 30-minute workout experience. We're so proud of them for all their hard work and can't wait to see them making members stronger, physically and mentally, back at their home studios. 💪

The speed bag (a fan favorite) is one of the best tools for improving timing, hand-eye coordination, and rhythm. Every hit challenges you to stay focused, find your flow, and keep your combos moving. It may look simple—but mastering the speed bag takes practice and patience. 🥊
