When doing a roundhouse kick, is there a rule for what angle the knee should come out at ? My coach says to bring the knee over at straight vertical angle 0 deg, and rotate the leg over while you extend.
In this angle below, the knee is out at a 45 degree right, while he extends the leg. My coach says not to do this. Is there a general rule for kicking? Or is each variation okay? green line below for reference
Another angle question, last question (Muay Thai Roundhouse Kick: Using Kick Shields vs Thai Pads, different technique?) was about final Rotation of leg. This is how about to bring it out initially.
