Rotate your hip and body whilst pressing your front left down keeping the back of your fist pointing up and in a straight line with the lower arm. The left hook to the body is similar to the above but increases the rotation of the body

The right uppercut is also carried out at close range. Drop the lower part of your punching arm until the lower and upper arm is at right angles to each other. The back of your hand should be pointing away from you, now thrust your arm forward and upward to your target.

Shift your body weight to your front leg and rotate your hip and shoulder on the same side. Remember to keep your left fist guarding your chin during the entire movement. Now practice all your punches until they are done quickly and smoothly.

To develop speed and endurance, try punching straight left and right combinations into the heavy bag. The duration of the exercise period is the same as the rest period i.e. 10 seconds exercise, 10 seconds rest, 20 seconds exercise, 20 seconds rest, and so on. Move up higher as your condition improves.

Believe me after you start applying Cardio–Boxing to your regular fitness workouts your cardiovascular and endurance systems will thank you for it.
