Assuming a straight punch:

Striking-

Forearm flexors - to make a fist

Triceps - to straighten the elbow joint

(Front) Deltoid - to raise the arm (parallel to the ground)

Pectoralis Major - to drive your fist through their face :)

Retracting-

Biceps - the opposite of Triceps, to bend the elbow

Latissimus Dorsi - the opposite of Pectoralis Major, to pull your fist from their

empty skull :)

Your main focus should be on speed and accuracy. Pecs and triceps are going to give you the power in your punch. Train your deltoids for endurance, if you plan on going round after round.
