I am new here.
When I am working on the heavy bag (hangs from the ceiling) I find it incredibly hard to throw my kicks after punches. My kicks get jammed up. Say, I throw a Jab, Cross, LHook and then I want to throw a RLeg kick. I find that I am too close to the bag to hit it with my mid/lower shin. Its my upper shin that makes the contact or my knee. My kicking technique is the following:
After the LHook, I take a small step with my left leg a bit forward and outward so my Lfeet is already pivoted (my toes point 11 o' clock). I do this to open up my hips. And then I kick while my left foot pivots (from 11 to 9 o' clock) on the ground.
In this video https://www.youtube.com/watch?v=3HOUGhau4UA at 0:52 seconds, Damien Trainor throws his RLeg kick after the LHook to the body. He steps in for the punches, and after his Lhook, he repositions his Lfoot backwards before throwing the kick. Its almost like if you play it real slow, for a split of second, both his legs are on air: the left (pivot) foot coming a bit backwards and the right leg on its kicking trajectory. He does not plant the Lfoot rather he picks it up and places it backwards. That seems to give him room to land his RLeg kick. Is that the right way to throw the kick? And he does that in many of his tutorial videos.
My sensei taught me to either place my Left (pivot) foot a bit out and forward to open the hips and then kick after the LHook, or just keep it on the same spot after the LHook and just pivot on it. I remember him telling the class not to pick the Left (pivot) foot up and put it backwards: that throws us off balance and reduces the kicking power.
