@OG - Eh maybe you could just try straining your body, as in, don't try to countertorque, just try only twisting in your hips, while trying to keep your upperbody facing forward, like for the first kick sure you can twist how you should be twisting, but twist back on the point of impact, the following kicks should be quite natural after that, when you're doing your roundhouses just think of one thing "I must do 3 alternating kicks in 2 seconds." you should be able to do it. It's like, you know, those pros that do alternating roundhouses that doesnt require them to down their leg first. I think the countertorque is the basis behind the power of those kicks because they barely even rotate their upperbodies around. On the other hand, since I'm heavy, I think I should do away with that, because I'm playing defensive, and my attacks most probably will hit if I block instead of dodging. I could use it to reduce distance or in case I miss though, because, yeah, I tend to overspin if I hit air, like even if I'm practising, so probably tts the cause for my natural development of countertorque.

When I'm doing the double up (alternating kicks) and I'm looking for speed not power I'm fine.  The counter torque is being used to suddenly turn the hip over just before impact to drive through the target.  You're spot on about the straightening the body up and sighting down the leg as it makes impact that along with the counter torque is the objective.  We all have things that we work on and things that come easy.  This is just one of those things that requires more of my attention than what I think that I should have to give to it.  If this stuff was easy everybody would be doing it .  Thanx for the tip, I'll give it shot.  Coach Ruiz keeps reminding me...relax you can't do this stuff if you're tense.  Just relax and throw the kick, and then he kicks me in gut for not breathing properly...tough love in our class. 

Lol, I can't do double ups [or multiple ups] to save my life and I definitely don't know how to put speed into it. Whenever I do it I use countertorque-ing to keep my body facing forward so that my whole body doesn't go spinning crazily left and right but my kicks end up friggin slow and heavy [probably bcoz im fat] and they go up at 70-80 instead of 30-45 deg. -.- They end up slower than alternating kicks with foot landing before the nxt goes up. So my best bet would be to land 2 roundhouses while i block his kick, which takes less time for me to reach him than if i sidestepped.

Yeah, I tried out my countertorque by looking into the mirror when I practiced my roundhouses just now. It seems that, when I don't deliberately use the countertorque, my shoulder [not so much the hips though] will counter my spin in proportion to my rotatiion force from the kick, my right kick is stronger, so my left shoulder will move more [towards the right] to stop myself from spinning out of control as compared to my left kick, which my right shoulder just fidgets a little forward towards the left - this is when I don't apply full force and full speed, but enough to create a clean pop sound on my heavybag, but not enough to cause the bag to dent in or swing around wildly.

So basically for me, my countertorques activates automatically if I'm about to overspin, and if I'm concentrating properly >_> I get distracted sometimes and go offbalance.

And probably because the tiles in my house is smooth-surfaced, I tend to overspin more easily when I practice at home [most of the time, only 1 class per week], which is probably why my countertorque develops faster naturally.

Btw at what angle does your (everyone's) roundhouse contact with the target? I've been contacting at 45-80 deg, and against the heavybag, but recently I think because of that the side of the instep hits, it's been receiveing the repercussions, like when I kick the heavy bag, the reaction force that the bag returns gets sent through my foot and now whenever I kick like that the right side of my right foot hurt. Only contacting directly at 90 deg works for me now. Knee + foot screwed.
