I've only trained two styles: back when I was young, a more karate-like version of taekwondo at a college club, and now the Kukkiwon style. I'm not an expert in either style, but here are some things I needed to unlearn/relearn when I reentered taekwondo:
- When I was young, we were taught to make our long-front-stances low, square, and stable. Now I'm generally taught to make my stances higher, narrower, and more agile.
- In particular I really miss my old Horse-Riding Stances which were nice and low, which made them fun, whereas now our Horse-Riding Stance seems boringly high to me. (I liked feeling that burn in my quads while doing punching drills!)
- When I was young, there seemed to be more emphasis on keeping my torso squared during the movement (moving just the hips) whereas now it seems I'm allowed to twist my torso as well as the hips. Newer taekwondo generally seems more "twisty" to me. (In fact, apparently we're now allowed to be so twisty that we even "teacup" the outside middle block when in a back stance!)
- While in both styles I was taught to twist my fist during the block or punch, in the older style it seems like the twisting motion was supposed to be fairly uniform through the movement, whereas now I'm supposed to save most of the twist for the end, to create more snap. (Sometimes we drill on punching out candle flames, which I think is fun. I don't think my old punch would be very good at that...not snappy enough.)
- Nowadays I'm taught that my inside middle block should lead with the elbow (again, to improve the snap), but that's not something that I was taught before.
- Generally, the chambers for many of the blocks are different. For example for an inner-forearm outside-middle-block, I'm now taught to chamber the blocking fist with the thumb against the body so that the fist can rotate during the block, whereas back in the day I was taught to chamber with the base of the blocking fist touching the body. Also, the old chamber was lower toward the hip, whereas now the chamber is higher on the ribs, I'm told to make the block faster. Again, more emphasis on "twisting" and "speed" in the newer style.
- In fact, there seems to be a LOT more emphasis on chambering now. Before the emphasis seemed to be on the movement and how it finishes...less emphasis on how you chamber at the outset.
- In the old days it seems like we didn't just drill on punching, we also drilled on knifehand strikes, ridgehand strikes, knuckle strikes, etc. Now it seems like when we're drilling strikes it's mostly just punches (with of course lots of knifehands appearing in the poomsae).
- Of course the foot position for kicks is very different now. Before the front kicks and roundhouse kicks struck with the ball of the foot rather than the top of the foot. But of course that only applies to things like breaking...in poomsae we're still taught to curl the toes back on front kicks and roundhouse kicks. But boy did the straightened toes feel unnatural when I first started Kukkiwon-style!
- I feel like my old side kicks were taught with more hip-turnover, so that they bordered on almost looking like a back-kick at full extension, whereas now the hip seems to be turned-over less. Also, there seems to be even MORE emphasis now on rotating the base foot more during the kick.
- As previously mentioned, we never even practiced double knife hand blocks or outer-forearm outside blocks, which is why I still struggle to make those blocks look pretty. (Hard to teach an old dog new tricks.)
- While we did practice things like spinning back hook kicks back in the day, there was nothing like the tornado kick in our club. Likewise, we did practice some jump kicks, but not as many as what we practice now.
- We do one-step sparring sometimes nowadays at my schools, whereas back in the day we did one-steps during almost every class. They seemed to have been viewed as being much more important back in that old club.
- Of course the uniforms were different. I like the pullover better than the crossover though. Back in the day we trained on hardwood floors (a racquetball court) rather than these sissy millennials that want nice cushy mats under their feet (kidding! My old knees like the mats.)
But how many of these things are truly difference in the
style, and not just differences in
instructor? That I don't know. I suspect lots of other people in this thread are in that same boat..."Well, I can tell you what's change since when I started...but is that a difference in style, or just a difference in the instructor?"
