As any martial artist will tell you, there are multiple benefits in martial arts training. Of course, the most obvious benefit is a knowledge of self defense which is one of the major reasons why systems were developed in the first place. Knowing how to defend oneself and loved ones in a potentially dangerous situation is an asset in today's world just as it was hundreds of years ago. Unlike often portrayed in the movies, training is not just about fighting. Many people take up martial arts for the fitness benefits as well. Training in Taekwondo and/or Krav Maga, will improve one's cardiovascular fitness as well as tone the muscular system. Strength will increase from the calisthenics usually employed within training but perhaps not to the same extent as working out with weights. But overall power of one's body will definitely increase since the techniques teach how to use strength effectively. Most people will also improve their flexibility significantly while training since entire ranges of motion from the body are exercised. All martial art styles will result in an improvement of one's coordination as well. Unlike many other forms of physical activity, martial arts also have a mental and sometimes spiritual element which not only improves the mind's focus but also helps in self control. Emotions such as anger and fear are better controlled through training.  Many martial artists can find an inner peace through their training.
