Karate is for everyone, but individuals and groups tend to differ as to how and what they wish to learn.
is without a doubt the best way to go. Traditional in this context simply means that the class is taught in a dojo, where the instructor is referred to as sensei. Students wear black gis (karate uniforms) and white hachimakis (headbands). There is a belt system. There is a strong focus on discipline and courtesy.

"Traditional" is a controversial word. An Okinawan stylist might view traditional as focused on kata, with no sparring component. Some school might frown on the amount of self defense taught. In this context it is only used to differentiate from the other types of classes taught in Tampa.
classes dispense with many traditional aspects of karate, including kata and sparring, and focus solely on learning techniques and behaviors to escape being hurt in a street fight or domestic dispute. Self defense classes are a hands-on opportunity to learn self defense. Participants also get used to yelling, and hitting a bag, since many people have never tried that before. Most importantly, students learn simple rules to escape harm, and how to keep a level head.
Self defense classes are an option for someone who lacks the time for karate training, although in the long run, karate training provides the self defense benefit, and added fitness and stress relief benefits.
In some settings, even the contact involved in a self defense class is too much. Also, recently aerobics classes have started to include martial arts techniques in their training. While it is possible to learn zero contact self defense, it loses most of its potency.
