Breathing exercises, such as those practiced in yoga, prepare you for the movements and poses to follow. Here's an example of a breathing lesson that can help asthma sufferers:
Get in a comfortable position, perhaps sitting with legs crossed on a floor mat. Keep your spine straight.
Breathe in slowly and deliberately, sticking out your stomach as air comes into your lungs. This should take about six seconds.
Exhale, drawing your stomach back in. Again, take about six seconds.
Repeat this ten times.
