@Whispered_Freedom There's no such thing as becoming a good martial artist with minimal effort. You must train hard to be good. No magic, just training. However, there are some arts which you might want to look into: First off, boxing. Learning movement, range, and timing in addition to making the most of what a small frame can deliver impact-wise is always good. Plus, the limited number of tools used makes for the best ratio of time in to fighting effectiveness I can think of. It's also really fun. Secondly, MMA training. You'll learn a little bit of everything, so very little an unarmed person can throw at you will be a surprise. By being exposed to fairly wide range of disciplines, you'll be able to figure out what you're naturally good at too. Lastly, I'll chime in for one of the arts i train in, Judo. Learning how to manipulate someone via their clothing is pretty handy. The ground work is similar to, but different than BJJ. In judo, ground fighting has a time limit, so it tends to be more focused on what works quickly. It's less of a chess match, in other words, and more of a scramble. Not do discredit BJJ or Catch Wrestling, since the ground game of both those arts is much broader than what the average judoka learns. The judo ground game is perfectly effective and functional for most purposes though. Also, judo's use of pins might be useful for restraining of recalcitrant clients. Just my two cents.
