If you
Hello, I'm training for a kickboxing competition in a few months. Would like some advice, comments from any trained martial artists out there. Especially strikers.
Oh boy. I'm going to preface this by hoping you have thick skin. It takes guts to put up a video for people to critique.
That being said, you will find a lot of experienced people here. Personally, I have been involved in the arts for 50+ years. My primary art is TKD, but like most I've cross trained a fair bit. And after 40 years in the ER, I'm in the unenviable position of having been in WAY more physical confrontations than most. So...
I hope you have a trainer other than YouBoob. If not, get one. Immediately. You have a lot of work to do (as does every beginner).
I hope the competition you're training for is restricted to rank amateurs. Anyone with much training or experience is going to murder you.
If that video demonstrates the power you generate with your strikes, you are in trouble. Honestly, I don't think I would even bother blocking most of what you show in your video. There are body mechanics that are used to generate power. You demonstrate none of them. When you punch, for example, it looks to be 100% arm. And that's not going to be useful.
Your balance is off, causing you to lead with your face, which leads to blocking strikes with your face. I don't recommend doing that.
You're leaving yourself exposed almost constantly. Just as one example (of many): at 4:08 you drop your hands. At 4:09, you are leaning forward, leading with your face, with your hands on your thighs. You do not bring them up at all until 4:10, and don't actually return to guard until 4:11. Three seconds with your face begging to be kicked into the next county. That's way more than is needed to get knocked out.
There's more, but these are all basic things, and that's the place to start.
I don't want to dampen your enthusiasm. Training is good. Keep training. Competition is good. Keep competing. But compete against people at your level. Going into a competition and being used as a tackling dummy is not helpful.
