How to Do a Breath Control Exercise for Rapping
You can improve your breath control and rap faster for longer with a simple breathing exercise. Start by exhaling as quickly as you can until your lungs are empty. Count for 5 seconds, then inhale fully in a single breath. Finally, take 3 normal breaths to bring your oxygen levels back to normal. Repeat the exercise for 15 to 20 reps 3 times a day or whatever you're comfortable with. This will help strengthen your diaphragm and help you rap for longer without taking a breath. You should start to see results within a few weeks. You can also improve your lung capacity by doing regular cardio exercise, like swimming, cycling, rowing, and jogging.
Exhale quickly and steadily until your lungs are completely empty. You'll feel your chest depress slowly as the air escapes your lungs; this will feel uncomfortable at first but you'll quickly get used to it. Start slowly when first performing this exercise. It's possible to hurt yourself if you release the air too quickly or too strongly. If you feel discomfort or pain, stop immediately. Keep your lungs empty for about 5 seconds. In doing this, you are fully extending the muscles in your diaphragm. This helps to condition and strengthen your diaphragm. It will improve your endurance and make you less likely to run out of breath. As you hold this position, your reflex will be to inhale. Resist this temptation or you'll limit the exercise's effectiveness. Fill up your lungs with a single quick breath. Inhale as soon as you've held your breath for 5 seconds. Once your lungs are completely filled with air, hold this position for 10 seconds. Filling your lungs this way helps to expand your lung capacity, meaning you'll need to take less breaths when you rap. Take a few (2-3) normal, steady breaths. This helps re-establish normal oxygen levels in preparation for your next repetition. You shouldn't perform the exercise multiple times back to back without resetting; this could injure your respiratory system. Repeat this exercise 3 times daily for 20 minute periods. Between the exercise itself and the recuperation between each “rep”, you should be able to perform about 15-20 reps per 20 minute set. Your 3 daily sets don't necessarily have to be performed one after the other; feel free to perform them throughout the day. For instance, you can perform one when you wake up in the morning, one around lunch and one just before bed. If you perform this exercise daily, you should see noticeable results within 4-8 weeks as your diaphragm becomes stronger and more flexible. Doing this will allow you to flow stronger for longer periods of time. As you're not constantly rushing for breath, you'll sound more confident when performing and have the ability to add more emphasis to your lyrics. Lie down in a pushup position. You should be on your stomach, your palms flat on the ground and underneath your shoulders. Keep your spine straight, and lower your head until your neck is aligned with your spine. Push yourself up and inhale. Press through your hands as you push yourself up. Your upper body should slowly start curving upwards, from your head all the way down to your hips. Keep your body still from the waist down. Inhale the entire time you're pushing up. Pull your shoulder blades together when you reach the top position, opening your chest further. You'll notice you need to strain slightly to take in a full breath. This opens up the chest and deepens your lung capacity. Exhale as you return to the starting position. Slowly bring your upper body back down towards the ground, allowing yourself to rest gently on the ground. You should be following the same curve as the previous step. Your chest should touch the ground first, followed by your shoulders, neck, chin and head. Perform this exercise 10 additional times. You can take a couple of seconds between each repetition to reset properly. You shouldn't be hurrying as you perform this exercise; the goal is to slowly learn how to control your breathing and expand your lung capacity. Choose the right cardiovascular exercise. Exercise is one of the best ways to improve your lung capacity and your ability to control your breathing. The type of exercise that's right for you depends on the equipment available to you as well as your limitations. For instance, if you have bad knees, running can cause pain and damage to these vulnerable joints. Some options for cardiovascular exercise include: Swimming Cycling Rowing Warm up and stretch before exercising. Not warming up properly can lead to a host of injuries, such as pulled muscles and sprained ankles. Perform a light cardiovascular exercise (such as jumping jacks) and stretch. Sprint, nonstop, for 20 seconds. This means you're pushing yourself as hard as you can for the entire 20 seconds. Rather than performing low impact cardiovascular training for extended periods of time, you'll want to use high intensity interval training (HIIT). While both are effective for improving your lung capacity, HIIT workouts are more efficient as they're usually completed in a fraction of the time. If you're already in good physical shape, you can increase your work time to 30 or 40 seconds for a more strenuous workout. If swimming, be careful not to push yourself too hard as you could risk drowning. Slow down and recover for 40 seconds. After your 20 seconds of work, lower your pace to a point where you're able to talk and catch your breath. For instance, if you're running, you'll slow to a light jog for 40 seconds. The pace should be just enough to keep your heart rate going while still giving you a chance to recover. If you're in good physical shape, try decreasing your recovery time to 30 or 20 seconds. Repeat this sequence 10 times. The total workout should take approximately 10 minutes to complete. Start by doing this workout a few times a week, and you should notice your lung capacity and breathing improve.
