One of the best known, and slow to be associated with the martial arts, is the art of wrestling. Hands down, the best way to take an opponent to the ground without using clothing is by using wrestling. Greco-Roman (under body) wrestling and freestyle (entire body) wrestling techniques are extremely valuable skill sets to possess or add to your arsenal, whether you are a kickboxer or Brazilian Jiu-Jitsu practitioner. Wrestling will allow you to dictate where you want to fight to take place. If you are a kickboxer, you can prevent your opponent from taking you down or if you are grappler, you can use wrestling to take the fight to the ground. Wrestling also has a tremendous amount of techniques on the ground.
