Why not hit with the 2nd knuckles?

I use the middle knuckle

I disagree with this, give me the first two knuckles on some guys chin over the last three every round of my life. The first two knucles will deliver the kinetic energy, that generated from your foot and through your body, all being delivered in a straight line of energy. The last three knuckles are off set from this 'line of power' that rolls through your body. The first two will deliver all of the power, the last three will be softer and less damaging. .......... Rockin'

he's talking about 2nd knucles where your fingers bend. the ones you crack.

not the knuckles on top.

2nd knuckles are too weak.

i've swollen up my top knuckles punching.

using 2nd knuckles is improper punching.

you can break your fingers.

Shit, you got 5 knuckles?

maybe he has 6 fingers.

Actually it's the exact opposite Rockin. The last 3 knuckles are in line with your power line as are the finger bones in your hand which are aligned with the bones in your forearm, the bone for your pointer finger isn't. The power line travels down the outside of your forearm/hand. If you punch with the first two (pointer and middle) your power line gets broken right at the very end and all that kinetic energy is exerting force on your wrist causing it to want to bend inwards.

In Dempsey's book he gives an excellent exercise to demonstrate the power line.

- Stand in front of a wall arms length away with a closed fist

- Your fist should be placed on the wall at your own chin level (in terms of height and centering it) and just barely touching the wall.

- Now lean slightly forward and start placing some of your weight behind it so your fist begins to press more solidly against the wall.

What you will find is the first knuckle that makes contact with the wall is in fact your pinky knuckle on the outside of your fist which demonstrates where the power line runs and where the transfer of energy to your target should take place. This is true whether you do the exercise with your fist positioned so it is palm facing the floor or palm facing inwards.

Dempsey states that the pinky knuckle is the weakest along with being on the outside of your fist which makes it too fragile and vulnerable so you move one over and aim your punch with the knuckle on your ring finger and land with the last three knuckles (pinky, ring, middle) AKA Three Knuckle Punching

Thank you very much.

I always wondered about this while hitting the bag. I felt more comfortable hitting with the last 2, but the majority were hitting with the first 2 knuckles.
