Vocal warm up exercises

There are basically three things they could do to warm up your voice.  You can do this every day and even before your performance.  First you can do a breathing vocal warm up exercises.  Just exercise your lung and your diaphragm.  You could also do lip rolls and other multiple vocal exercises.

If you want to improve your singing voice you should learn how to monitor your breath to improve your singing voice.  Do not expand your chest as it is a process of incorrect breathing.  Instead, while inhaling you should expand your stomach.  To do this, you should use your diaphragm muscle.  To strengthen your diaphragm muscle as well as your stomach muscle, try doing crunches.  It’s nice to have a good posture because it plays a key role in improving your singing voice.
