Three minutes on. Rest. Three minutes on. Here's why it works.

Round structure on BOX12

Three minutes on. Rest. Repeat.

Three minutes on. Rest. Three minutes on. Rest.

It's a simple structure — but it's the one that's powered boxing training for over a hundred years. And it's what makes a session on BOX12 feel completely different to anything else in the gym.

Each round, you go hard. The timer tells you when to push and when to recover. Then you reset and go again. No guesswork about how long to work. No fading halfway through because you went too hard too early.

The structure does the thinking. You just bring the effort.

36 minutes. Round after round. Every session.

Step into BOX12 and feel the difference.
