Double leg takedown is probably the most utilized and high percentage takedown in MMA. And it is not only used in that sport, but also in many others like freestyle wrestling, BJJ, grappling, sambo, sanshou…etc.
First lets look at the key principles needed to execute a double leg takedown. First you need to be within arms reach before shooting in. Any farther and its telegraphed to the point that even a boxer can sprawl out of it. Second, you need a level change where your going lower then your opponents mid section, but with good straight aligned posture. This means not making your back look like it has a camels hump. Third, you need a deep penetration step where your foot steps between your opponents feet. Way to often the penetration step is far to shallow. Once you get to this point the variations start to kick off.
The blast double leg is the same thing as the regular double leg, except that your head goes in your opponent’s chest instead of the side of the body. You basically run them over and since you are going straight and holding their legs, they are unable to sprawl.
