Muay Thai Roundhouse Kick: Swivel vs Step
 

Im Starting MT in Jan and have been home training for 6-7 months and have spent alot of ime on strength, cardio and conditioning.
My friend who trains MMA (Kickboxing, Mt and Judo) has been teaching me some Mt techniques as i am totally in love with it, and i have not any problems at all apart from the roundhouse kick.
When watching videos on the web, some say to step at a 45 degree angle and then kick whereas some say to just swivel on the ball of your foot which it seems Ramon Dekkers does.

so my question is should i swivel or step because i am aiming all my kicks to the knee/thigh and have decided that my tatic would be that if im to far top just swivel on he bal of my foot then to step and kick.
is this a good idea?

thank you for taking the time to read this.

Whatever is most comfortable. FWIW I pivot for quicker kicks, step for power kicks.

well the first thing is do not aim a kick at someones knee in training or sparring, you will become very unpopular very quickly...
kicking the thigh is fine but don't hit the knee

as far as swivel or step honestly it's more preference/situation then to say one is always superior to the other
in my experience honestly I use both depending on the situation and my opponent
the swivel is quicker and gives less warning to the other guy, but the step is a harder impact
