What self defense classes do you recommend?

I trained Krav Maga for several years. It is very effective, because it uses quite cool "reflexes" and the physics of the attacker's body. Simple moves can "turn off" the attacker for a few or even several seconds, which gives an effective time to escape or call for help. Personally, I recommend.

Krav Maga is definitely a good option because it is a system focused on self-defense, it teaches you to neutralize your opponent as quickly as possible and escape. The system focuses on simplicity and ease of implementation, i.e. the best effect with the lowest possible expenditure. Of course, in order to acquire fluency and efficiency, you need to practice regularly. However, after just a few months of training, you can learn useful techniques that can help us in a crisis situation. Certainly, the training will help increase self-confidence, tame the situation when someone attacks you and show you how to react. In addition, usually most of the trainees are men, so in the case of women it helps to get rid of mental barriers related to confrontation with a man.

By definition, the most effective sport is MMA. It is a combination of different sports to increase their effectiveness. If you want to train 2-3 times a week I would focus on grappling (wrestling and Brazilian Jiu Jitsu).

But I wouldn't count on miracles. A man gains a nice level after 2-3 years of systematic training. In women, due to the fact that they are much weaker, this time is longer.

He suggests pepper spray and taking care of your own safety. I highly recommend MMA, but as an addition to myself.

Currently training Krav Maga. Low entry threshold - anyone can start with no skills. Focused training has a specific action on how to effectively repel the attack. During training, various attack and defense scenarios are worked out. We learn to use objects and things that surround us on a daily basis for effective defense (e.g. a chair, a backpack, a hoodie, a knife, etc.). In addition, there are also classes in the military version of Krav Maga, where we learn techniques of fighting with firearms. Clubs sometimes organize special events, e.g. training and defense in a moving bus, bar fight, etc.

Cool story

Just be aware that you won't learn it over a weekend or a month, you have to practice systematically for years. We can list different martial arts here, which one is better etc., find out more about what is in your area, what are the activities and then choose something from it.

Not enough data. It is not known whether you are 155 cm and 45 kg or 180 cm and 75 kg.

I knew 2 people who trained Krav Maga. One of them was a petite woman, she learned various tricks, effective regardless of the body weight of the opponent. Gouging eyes, crushing testicles, tearing lips, tearing off ears can very effectively discourage evening lovers ;) Stay safe.

You really have to be careful, especially at night

I am a martial arts and self-defense trainer with 34 years of experience. I think that's enough to confirm my competence ;)
When someone asks me what martial art is suitable for self-defense, I answer - any and none.
Each, because systematic training "builds" us not only physically but also mentally - we develop in technical and motor terms and this affects our attitude, which sends feedback to a potential attacker: "I am not an easy target".
None, because often in the arsenal of martial arts there are techniques that are not suitable for self-defense. For example, they are too complicated and the physiological reactions occurring in a dangerous situation cause us to lose the ability to perform precise movements. Techniques can also be too dangerous - both for us and for the attacker (and this raises the possibility of legal consequences).

Krav Maga is not a system that can be judged "zero-one". It all depends on the instructor. Unfortunately, there are many who give up baja-bongo. I also know people who are great.

If I were to advise you on what to choose, I would need some additional information.
First of all, should it be systematic training or not?

If you are looking for self-defense classes, then it is definitely worth taking an interest in different fighting styles that are effective in emergency situations. Krav Maga is one such style that is used by the Israeli military and security agencies around the world. It is a combat system that focuses on simple, intuitive movements and techniques enforced in real-life situations to quickly and effectively neutralize the threat. When it comes to other fighting styles, it is worth getting interested in such systems as kickboxing, boxing, judo or karate. All these styles have their advantages and effective techniques that can be useful in emergency situations. In conclusion, the choice of combat system depends on your preferences, goals and expectations. However, it is worth realizing that self-defense is not only physical skills, but also knowledge of how to avoid potential threats and how to act in emergency situations.
