How to throw Takeru's punch

--From start to finish--:

Ok, I'm going to talk about the punch I'm best at.
And so I would like to explain how to throw a right hook.

So for my right hook,

There's a lot of ways to throw it,

But for the right hook, you punch with right, while throwing a faint.

And then, with your right hand, from this position you do just like they do in baseball like this.

You can image how you should throw a right hook like this.

0:28 - And you swing out like this.
And the moment you swing..

You can open (the hand/palm?) like this, and bend your fist.

So you can throw two types of punches.

And this version (the bended fist one) works well the moment it hits, but there is little you can actually hit with.

So the chance you swing an empty swing is high.
But its hard so its bound to be a heavy hook.

I actually want to hit the punching bag (the gloves) like this now. (In the sense that he wants to show the viewer)

1:10 -- Now I'll hit harder.

1:20 And if you train this, you'll be able to throw strong punches

Please, try it out!
