Oh,ouch. Probably wouldve been a better idea to tie this guy up and go for the takedown then give him distance to generate those powerful capoeira spinning kicks... Nice K.O.
Meia Lua de Compasso (Rabo de Arraia): Staple move. When you step behind during the Ginga, keep your feet where they are and shift your weight over your front leg (by stretching your rear leg). Bend your upper body inwards and down. Reach down with your hands until your hips can't get twisted any further; drop your head so you can keep constant eye-contact with your partner. By now great energy should be created by the tension you built up. Unleash this power by taking off your rear leg; it should fly around in a quick half-circle without any muscular effort. Always hit with the heel! Once your kicking leg is aligned parallel with your upper body, finish the motion by rotating your entire torso until you face your partner again. Watch out that you don't get hit because of raising your head too early - Meia Lua de Compassos are often answered with further Meia Luas.
This is one of the most common yet difficult moves, but with constant training you will be able to deliver fierce single-handed Meia Lua de Compassos within fractions of a second.
