The blast double leg is a great takedown for non wrestlers and sub wrestlers 1) it's near impossible To thedo this version of the double leg bent over or in a wrong position so it re inforces good mechanics for the other double leg variations 2) head in the centre allows for a higher position which makes the sprawl as a defence harder and allows you to hit it without going to the knee on the penetration step great for those of us that are older 3) head in the centre takes the guillotine out of the equation allowing you to go straight backwards into guard if you want to.
That's how I was taught in freestyle wrestling to do a double, didn't know it was called a blast double recently had someone from another BJJ club doing his doubles that way, I always wondered why it was taught differently.
We call it a Japanese double. Well, the Japanese Double is normally with a bit more of a headbutt....
Same. Straight back, forehead up and into the middle of body and drive knee past and between the legs. I suck at that one lol! I'm more of a single leg and collar x tie guy.
