Everyone needs a way to blow off steam. MMA offers a variety of ways to do it. Boxing and kickboxing lets you hit pads and heavy bags. Jiu Jitsu lets you wrestle. Sweating, engaging in physical activity, learning something fun and new, meeting and working with friendly people of all ages, you forget about all the stressful factors in your life.
If just for a few hours a week, you can step away from the stressors in your life. Tests, homework, grades, your home-life, slip away. When you return to them later in the day or later in the week, you can do so with a clear head.
