I don’t teach kids, but when I did…
It’s about keeping their attention and playing games that are somewhat physically demanding for a kid.
co-ordination balance and structure are important to develop in children. When they are aware of posture and stepping etc, it will benefit them greatly as they grow into the art further.
there should not be any full contact striking against each other at all whatsoever until at the very least they are in the 16-18 yr old range.
Not only for liability concerns, but because of real physical concerns. IE: a kid is not developed, their bones are still forming and their skull is not completely sealed until at least 18 years old.
so games in the spirit of kung fu that encourage and produce co-ordination, balance and comradeship amongst them.
form is also a good place for kids to start.
For older people, it is a concern to me personally that they actually have the guts to fight. this can be read pretty quickly with light sparring, gloved up, headgear etc. You can get a look at how the person moves and feels about the situation as it is going on.
heavy bag can show good or bad structure.
mitts can show good or bad timing, reflexes and footwork if you get that in there.
Depending on where a persona is at, they could start from anywhere. But typically it’s first, develop strength and condition. When that is good or solid, move on to technique. Move that to drills, move that to sparring then build, rebuild and keep building.
by the time the law of diminishing returns kicks in, you should have yourself a pretty handy individual.
Practice on their own cannot be encouraged enough. This is where most fail. Quite frankly it takes some time before a person develops good practice habits. Basically, they really have to want to succeed to get into good habits.
That’s something you cannot turn on or off. It’s either there or it’s not. Either way that’s ok.
I still won’t teach kids. lol (mostly because they bring all their parents’ baggage with them)
