Place your feet a little wider than shoulder-width apart. When in doubt, place them apart a little further. Lift your back foot heel up, and keep it lifted. Don’t be “flat” footed. Point your toes in the direction of your punch. Pointing your feet away from your target will deliver a less forceful punch. Keep your knees bent. When you punch, your knees can then extend, giving your punch extra power.
Use your hips to swing your torso back. Think of it like cocking a gun. Then unload by reversing your hip movement, swinging your torso towards the target.
Keep both your arm and fist relaxed until immediately before contact. As you feel contact with the opponent, tighten your fist. A relaxed fist will travel better through the air, but a tight fist will deliver more of a punch. Punch straight with your arm, not with an arc. You might be tempted to trace a long arc with your punch, but don’t: Remember that your power comes from your hips and torso, not from the path of the arm. Don’t cock back your hand or arm. This is called “telegraphing,” or showing the opponent what you’re going to be doing before you do it. [5] X Research source

Start off by doing 12-15 reps of punches on one hand, and then switch to the other hand. Try to shoot for 10 sets on each hand; do this daily. Remember to not overtrain your dominant hand at the expense of the other. If you have an obvious weakness in one hand, focus on training that hand. In a fight, a smart opponent will try to exploit your weak side. Not giving him an exploitation point will make you a stronger fighter. Gradually increase the weight as you become accustomed to the lower weight. Increase your weight will make your arm-strength and speed increase without trying you will get knocked out. Never punch a punching bag with dumbbell weights in your hand. Only air-jab with weights in your hand.
