So I found the punching guide and checked how I clinch my fist.
Now the funny thing:
I did it right. 'Rolling' in my fingers, fold the thumb over the top knuckles. And than the index finger is pointing out far above all other fingers. If you look in the punching guide the picture with the 'straight line' of fist and forearm, the clinched fingers goes from top of the hand in 90° downward. On my fist every finger does so, except the index. This one is more 45°. And I can't clinch it diffrent or do anything else to get the correct form. I'm assuming it's because I lack one thumb join. Or actually I don't lack it, I just can't use the 'MP' joint.
So there is a buckle bulge where the tip of the index finger should be which let it stick out.
So my question:
Is there any chance to still hit with my base knuckles AND keeping a straight line? Or at least avoid skinning my middle knuckles without buying gloves?
