Sometimes when battling ninjas I like to jump from the roof of my chinese house with my robes making a pleasant flapping sound in the wind and land improbably on the top branch of willow tree- it offers NO tactical advantage, but it makes me look DAMN cool and the ladies like it
sometimes a little jump will add some power whilst sacrificing your base to a degree, use conservatively...
in other words, yes you may fly, but not too high Icarus, not too high...
flopping around like the guy in the video from soft gay porn fantasy flick "Never bite down" is not recommended
its a whole funky skillset all of its own delivering punches, knees, elbows and kicks with a little "skating" jump, attend your nearest traditional muay thai class for more details
