Ok, who are we kidding. Jiu-Jitsu is work. In many ways it is one of the most complete workouts you will ever discover. When you are done you will feel muscle aches where you did not know muscles existed and you will be covered in sweat.
But if you are like the majority of people who practice the art, you will not even be able to tell that you were working. Taking the time, learning the maneuvers, then putting them into motion against your classmates. Quite frankly, its fun. You are engaged mentally as well as physically so the time does not drag by, and you are working closely with a group of people that are as enthusiastic about Brazilian Jiu-Jitsu as you.
If you don’t believe me then try a class for free and see if it isn’t exactly what you have been looking for in a workout program.
