Knock Them Out!

Unleashing the Uppercut.
 Most knockout punches in boxing occur on the chin due to an uppercut.
If you don't know, get into a good fighting stance. Left or Right foot in front(whichever is more comfortable), Bent knees, Chin lowered, Jaw guarded. YOU don't want to get knocked out.
In one motion bring your body lower, pivot to the arm your punching with and bring your elbow back. This generates power.
In another motion (this is the punch) push your legs up, re-pivot and bring your fist up. Hit that chin.

Hooking the Head. Hooking the Head. A hook is always another sure power punch that can leave your opponent going to bed early. Of course the fighting stance.

 (Step 1 in "Unleashing the Uppercut") Before the punch, know that a good hook is not a wide arching one. It is a short compact one. Keep your forearm to a 90 degree angle to your bicep and have your fist in the vertical position so you won't break any bones.In one motion (this is the punch) Pivot in the direction you are punching in bringing the hook with you. Aim from the ear to the temple.
