Breathe Fire
If the name alone doesn’t make you sit up in your chair, the results sure will. The yoga breathing technique known as “the breath of fire” is a series of rapid, forceful exhalations that stimulates your sympathetic nervous system for an instant charge.
Start in a seated position with your hands just above and below your bellybutton. Quickly contract your abs in and up, pushing your diaphragm toward the lungs and forcefully exhaling through your nose. Then let your stomach relax and inhale through your nose. Repeat 10 times, working up to three breaths per second for 60 seconds.
