Cardio boxing
Let's start with the most popular one: cardio boxing. A US import in the early 90s, this variant is based on kickboxing, boxing and Muay Thai movements, with the aim of exerting yourself and burning calories. That's lucky, because that's exactly what you're after.
The aim of cardio boxing isn't to perfect your technique so that you can do fights, but instead to use boxing exercises and movements to train your cardio and channel your energy.
And to mix business with pleasure (and to help squeeze out that extra drop of motivation when you're starting to flag during the class), everything's done to music! Whether you're at a boxing club or gym, classes are run by a coach against a backdrop of funky lighting and music.You won't be able to resist letting off steam and working up a sweat.
And that's exactly why cardio boxing is a great way of expending energy. What with movements where you're punching the air (shadow boxing), exercises where you hit a target (punching bag or focus pad), fitness exercises and skipping sessions, you're sure to burn off calories: 600 per hour, on average. It makes perfect sense when you think about how intense boxing training is.
In a nutshell: Cardio boxing is a chance to take advantage of the intensity and quality of boxing training - both cardio and muscular - in a fun environment that focuses on fitness rather than fighting.
