When you review a product like movies, book, music, etc, it is easily distinguished as a review. However, when you talk about martial arts techniques and its different aspects, it seems difficult to understand. For example, in this post, I talked about how to defend yourself against collar grab.
When someone grabs your collar and his hand is straight and elbow is not bend, you can use the first technique. If the attacker's elbow is bend, the first technique will not work, you can try, but you will not be able to release his hand from your collar. So in the situation, you can use the second technique that I said in the post. If there is a group of attackers, you have to deal with multiple attackers, you can deal with this situation in many ways. I gave my opinions about how you can make some change in the technique and use the first attacker as a shield to defend against multiple attackers.
Hope there will be a platform in the future where we can talk about different self defense techniques and give our opinions how realistic that is as a review. Thank you so much @knowledges for taking the time to read my posts and giving your feedback. I wish you good luck and success! :)
