Strikes that come from the side (rather than straight on) can often be sneaky. My guess is that it has to do with how fine tuned a person is to their peripheral vision, and whether they can 1, visually see and 2, perceive the sideways motion as a threat. A hook punch is an example of this sideways strike; and when kicking, the roundhouse kick acts in the same way.
The target for a roundhouse kick can be high or low. If your want to be able to execute a kick with height (eg, a kick to the head), you need to work on your hip mobility (that’ll be addressed in another Bando minute). If you want to fight in a tournament, you’ll need to be able to get your kicks approximately waist high. (Many tournaments have rules that forbid kicking “below the belt”.) In self defense, a kick to the thigh or the lower leg can be effective, so even if you can’t kick at someone’s head, roundhouse kicks are still a good tool to have in your arsenal. Today’s Bando minute is about your balance and control.
This is another exercise that takes advantage of a folding chair. Having a physical chair lets you know if you are actually clearing the height you’re aiming for. (And if the chair back is too high, you can use a shorter chair or other item.).
