Leida, after your last response of not wanting to spar, I highly, HIGHLY recommend Gracie Jiu Jitsu if you can find an awesome location that.
1. Is full of kind, considerate easy going people. Watch the class and be on the lookout for warning signs like LOTS of health tape, if its really typical you might even hear someone yelp or get injured right then! Good Jiu Jitsu is gentle and technical.
2. People should be smiling and having fun before, during, and after training
3. The little guys or gals should get the better of bigger beginners (who usually struggle like crazy) pretty easily while still smiling.
4. Look for a women's only class if that'll help you feel more comfortable, but try to go co-Ed ASAP. Any place that can retain plenty of women AND teach Jiu Jitsu is usually a comfortable place to train.
I don't like to speak out against any other types of classes, however I can't urge you enough to NOT SWTICH from Hapkido to Tae Kwon Do, or something else in every strip mall. I have personally tried nearly everything under the sun, And have tight countless adults who have regretted taking something less credible under the illusion it provides self defense. Some things are just naturally more effective than others. Some classes are more sport oriented, and some have a balance of both.
If its for fun, have fun, if its for self defense be certain you're getting your money's worth.
