Boxing is a cardiovascular workout that you can do in the comfort of your own home, without the use of any equipment. You may think you need to have a heavy bag or at least a small speed bag to start boxing, but this is not the case. Shadowboxing requires no equipment; you box your shadow or an imaginary person. Beginners and pros use this form of boxing to practice their technique. You do not actually need to see your shadow; you can stand in front of a large mirror or just in a large, open space.
Focus on a single move for one round, like the uppercut. After that, move on to another movement, such as the jab or punch. This will help you learn the movements and focus on technique. After completing a round of each movement, try different combinations of them for a few rounds.
Throw as many punches as possible in one round for speed boxing. This form of shadowboxing will not only get your heart pumping, but it will also drill the movements into your head. You should still be focusing on the movements to ensure you are performing them correctly, but your main priority is to throw as many punches as possible in a round. At the end of the round, take a quick breather or move right in to the next set. Try performing different movements each time and count how many you performed so that you can track your performance and compare it to future workouts.
Focus on your feet with movement shadowboxing. This form of shadowboxing does not require you to start throwing punches just yet. Concentrate on your boxing stance and how you are actually moving around. You can move side to side, forward, pivot and so on. As you begin to feel that your footwork is good enough, add some punches and jabs.
Shadowbox an opponent by looking at your reflection in the mirror or by simply imagining one. In the mirror, you can see every move you make and critique your own technique. Even imagining an opponent will allow you to focus on your movements and notice when you leave your body open or don't land your punches on target.
Perform every movement in slow motion when you really want to focus your energy on your technique. Go through all the motions, but very slowly, ensuring your technique is perfect. Great technique will lead to speed.
