Kalaripayattu is practiced in a special building called kalari. In the past there were several types of kalari. To this day, only two of them have remained popular – ceru (used for traditional medicine purposes) and kuzhi (training place).
Traditional kalari were built around a rectangular pit with dimensions of 12 x 6.5 meters. The bottom was encircled by clay walls and these on the other hand were strengthened with wooden beams. The 9 meters building was topped with a gable roof made of coconut leaves. This specific construction helped keeping the temperature as low as possible in very hot Keral climate. It was thanks to the light roof which made it possible for the cool wind to get inside at the same time blocking sunlight. What is more the high ceiling facilitating the circulation of air and the way kalari was build into the ground helped keeping the inside temperature low.
It is worth mentioning that even in Kerala, many masters transfer their kalari from traditional huts to modern buildings. One of the reasons is, paradoxically, the costs - the roof of coconut leaves must be renewed each year, and the professionals are very few.
Training
Before going down to the kalari, you should take off your shoes. At the entrance, a ritual follows. The student enters the kalari with his right foot, kneels and successively with his right hand touches the earth, then the head, and the heart. It has a symbolic meaning - what you learn in a building is understood by the brain and then - by the heart.
When we are in the kalari, the training begins. It is divided into three parts. The first one is preparation - the participants dress in langutti, it is loincloth covering the genitals and buttocks. This skimpy outfit is associated with the Indian climate, in which practicing sports in many layers of clothing is impractical. Next, the participants apply oil on the whole body. Oil helps the body to cool down when it is heated up due to ardent practise or protect the body from cold during the monsoon season but what is most important, oil increases flexibility of the body. Then comes the time for religious rituals. Hindus pray for their gods while Muslims look towards Mecca. After that, there are rituals of thanksgiving addressed to the gods, to the weapons, to the teacher, and many others. Finally, the exercises begin.
Warm up and repetition of the fight forms and kicks (more on that later) are followed by four sections of fighting - unarmed, fighting with sticks, fighting with white weapons and unarmed fights with special emphasis on marmas (by Tamil Medicine key points of the body used in Kalaripayattu during massage and fighting). When the first section ends, less advanced students have to leave the kalari. This elimination process is repeated after subsequent sections. Weaker and less advanced students can not look at the next stages of fighting so that they do not get bad habits out of them.
The section that exercises unarmed combat begins with mudras. These are Hindu and Buddhist symbolic gestures that strengthen the body (also used in yoga). Then, adavu exercises are performed (shifting from one fighting position to another, push-ups, squats and jumps). Mudras are repeated 6 times and adavu 18.
All the excercises are followed by armed training. In that section students practice using sticks, white weapons and emphasis on marmas. Both white weapons and ordinary sticks are highly respected. Grabbing a weapon, the warrior must apply it to his head, and then to the heart - a gesture analogous to that which he performs while entering to the kalari.

Some of the techniques:
• Six basic kicks:
-Nerkal – the kick is delivered above the head, with a straight knee and the toes extended.
-Vitukal – circling kick, from outside to inside; the stretched leg is circled in front of the body, with the foot reaching above the head.
-Akamkal – circling kick, from inside to outside; the stretched leg is circled in front of the body, with the foot reaching above the head.
-Konkal – similar to nerkal, but the right kick now goes towards the left shoulder, and left leg to the right shoulder.
-Tiriccukal – three straight kicks thrown by the same leg, while pivoting two Times 180 degrees on the other leg.
-Iruttikal – after having thrown a straight kick, the kicking leg sweeps back a bit behind the body. At that moment the practitioner shifts body weight to the hind leg, and squats down on that leg, while the inactive leg is kept forward.
• Vadivu, or the body positions during the fight (together with the cuvadu, that is feet positions during the fight form adavu):
-Gaja vadivu – pose of the elephant – feet parallel at shoulder width while crouching in a way that the knees are bent at 90 degrees.
-Simha vadivu – pose of the lion– similar to the position of the elephant but feet are put perpendicular and a bit than shoulder width apart.
-Asha vadivu – horse stance – one leg straight put behind, the other with the knee bent at 90 degrees put in front
-Kukkuda vadivu – stance of the cock – right leg raised with the big toe pointing up.
-Sarpa vadivu – stance of the serpent – similar to the position of the horse but upper body is more upright. In that way it is easier to turn 180 degrees.
-Marjava vadivu – pose of the cat – a crouching pose.
