BOXING KEEPS IMPROVING YOUR BODY
Boxing will keep you on your toes. Unlike running on the treadmill, there's always something new to learn.
"Boxing is a never-ending fitness challenge," Karina says.
No boxer has mastered all aspects of boxing, so when given a knowledgeable boxing trainer, it will never get boring. And that means your muscles will never know what to expect, so your body will continue improving too.
