Humans and the T-Rex dinosaur have a lot in common: for our size our upper body strength leaves a lot to be desired. As a result we have to work hard to maintain speed, dexterity and build strength. World Breaker is an upper body combat moves (that make you smart) workout. It will make you sweat (which is also good for you), and it will make you feel more powerful, more capable and stronger than before.
