After training in BJJ and kickboxing for several years I was handicapped eleven years ago, an unrelated issue. Then I found Krav Maga! BJJ is great for a workout along with dominating someone while you are on the ground too. Krav Maga teaches you to dominate attackers (plural!) all while standing up. Now this is just my opinion and experience. Yet Krav Maga was born from Israel as a real world self defense in the toughest portion of the world today. BJJ is an art from Brazil born in the world of MMA.
