Butterfly Twist
The Butterfly Twist, or commonly called B-Twist, is a Buttefly Kick with a 360 degree rotation.
The B-Twist will be the first twisting trick for a lot of people and can be a bit of a challenge to learn. However there is an easy way to progress into it, using the tsunami.
01 Tsunami Kick
Also known as stepover hook kick. It's such an useful trick. You should learn it. It can also be used to learn the B-Twist.
If this is your first twisting trick
The move you just learned is not much by itself, but it can help you a lot with learning how to twist. This "Tsunami-no-kick-hyper"-thing is already a full 360 degrees of spin. You can drill this move to get used to twisting from one leg.
04 Add a Setup
Now you are going to add the momentum steps, which are also used for butterfly kicks. You can do this slowly if you want to. It starts to look like a b-twist, doesn't it?
05 Slanted B-Twist
Next step add the dipping motion that is also part of the Butterfly Kick. This will make you go a bit more horizontal. Also spot the floor now. Practice these two progressions a lot! So now we went from vertical B-Twist to a slanted one.
Tips
Swing your arms wide as you setup and then bring them close to your body for the twist.
This is a very safe method of learning this trick but can still be unpredictable if you are unfamiliar with twisting. Either practice the prerequisites over and over again (which you should do anyways) or learn this on a safe surface.
