Fitness. Focus. Fun. That's what you'll get at Studio 4 Martial Arts, which is focused more on helping people develop excellent character and self-esteem and less on getting all "hi-yah!" on a stack of bricks. (Stay long enough, though, and you'll learn cool tricks like that too.) The cool moms are opting out of soccer practice and instead bringing the tots here to the instructors, who instill respect, focus, and positive attitudes in kids — without costing their parents an arm and a leg. No contracts are required at Studio 4, so you're free to check it out with no strings attached.
