Respiratory fatigue is a big no-no in pranayama. If you feel any fatigue or straining  at all  during practice, lie down in savasana, as Thomas is doing here. Don’t push yourself, and do not allow your heart to increase. Once rested, you may continue.  
  End each session with savasana for a minimum of five minutes.
