Imagine for a moment you are out with your friends and some big, obnoxious, drunken fool decides he wishes to dance with you. After you politely turn down what he considers a generous offer, he becomes belligerent and wraps a big meaty hand around your wrist. This is called a wrist grab and when it comes to brute strength you know you will probably lose.

A wrist grab is  easy to escape when you combine the twist your body with a sudden twisting movement of your hand against your captor’s thumb. You wish to work against the thumb because it is the weakest point in his grip. Wrist locks are a horse of a totally different color.

A wrist lock is a submission technique that often involves an opponent bending or twisting your hand in such a way pressure is placed on the nerves and bones of the wrist. A small amount of pressure can cause severe pain in the person being held while the appliance of more pressure can actually break the wrist itself.

Surya Namaskar, the Sun Salutation, is a series of 12 postures performed in a single, graceful flow. Each movement is coordinated with the breath. Inhale as you extend or stretch, and exhale as you fold or contract. The Sun Salutation builds strength and increases flexibility. Different styles of yoga perform the Sun Saluation with their own variations. However, the flow presented below covers core steps used in most styles.

Wujimon started to incorporate Yoga’s Sun Salutation into his morning routine. His goal is to do 2 sets of the sun salutation every morning as a way to increase overall flexibility and strength.

Sanseru means “36 hands”, and is also referred to as the dragon kata. It also focuses on fighting in all four directions.

It begins by sliding the right foot forward into Sanchin Dachi and performing Morote Chudan Yoko Uke. Pull the left hand back into chamber and throw a Chudan Seiken Tsuki, followed by a Chudan Kake Uke with the same hand. Slide the left foot forward into Sanchin Dachi and repeat with the opposite side, followed by stepping forward with the right foot and repeating the punch.

The omoplata is a commonly featured shoulder lock in Brazilian Jiu-Jitsu. The locking mechanism is similar to the kimura lock, but instead of using a figure-four, it is applied using a leg. The omoplata can be applied from the guard, by placing one leg under the opponents armpit and turning 180 degrees in the direction of that leg, so that the leg moves over the back of the opponent and entangles the opponents arm.

At aesopian.com posted a tutorial for the reverse/inverted omoplata:

If the crucifix is underused, then the reverse (or inverted) omoplata is almost unknown or at least considered an exotic novelty. Hopefully, this instruction will help change that.

A possible reason for this is that one of the hardest parts of the reverse omoplata is simply having faith in it. When most people are taught it, they blow it off as some impossible technique without even giving it a chance.

A Japanese sword is one of the traditional bladed weapons of Japan. These are categorised in several types according to size and method of manufacture.

The most commonly known type is the katana, which, like the similarly formed tachi, is a single-edged and, usually, curved long sword which was traditionally used by samurai from the 1400s onwards; Wakizashi is the shorter sword; Tsurugi are double-edged long swords; Ōtachi or Nodachi are older but longer single-edged versions.

Japanese swords are still commonly seen; antique and modernly-forged swords can easily be found and purchased. Modern, authentic nihontō are made by a few hundred swordsmiths. Many examples can be seen at contests hosted by the All-Japan Swordsmiths Association.

At the taijiquestion-blog he writes about the the Japanese curved sword:

In my last post I mentioned that curved swords are considered to have certain advantages over straight swords.  I then immediately started talking about sickle-shaped weapons of a type that are distinct from the general run of “swords”.  This was confusing, I now realize…

I really enjoyed reading his thoughts on the matter and loved his blog in general.
