We're teaming up with 9Round, the global kickboxing fitness brand with 700+ studios across 17+ countries, for a Sunday session that's open to everyone. Grab your sister, your mister, your bestie or your gym buddy and come sweat it out together!

9 rounds. 3 minutes each. 30 minutes of pure fire. 🔥

🏋️ Rounds 1–2: Strength & functional training to fire you up

🥊 Rounds 3–8: Kickboxing HIIT. Punch it, kick it, own it!

💪 Round 9: Core finisher to seal the deal

A certified trainer has your back the whole way, counting you through every round and fixing your form. You'll wear a heart-rate tracker too, so you can see exactly how hard you're working, live.

Never kickboxed before? Perfect. Beginners are welcome, and pros are too.

How it goes: Say hi to the 9Round crew 👋, fill in a quick form, get strapped into your heart-rate tracker, warm up, and then it's go time!
