Try this when you go for a walk by yourself🚶🏻♀️🚶🏻♂️ Measuring your breath by your footsteps👣
Walk slowly and leisurely in a garden, along a river, or on a village path. Breathe normally. Determine the length of your breath, the exhalation and the inhalation, by the number of your footsteps. Continue for a few minutes⏳. Begin to lengthen your exhalation by one step🦶🏼. Do not force a longer inhalation. Let it be natural. Watch your inhalation carefully to see if there is a desire to lengthen it. Continue for 10 breaths.
Now lengthen the exhalation by one more footstep🦶🏼. Watch to see whether the inhalation also lengthens by one step or not. Only lengthen the inhalation when you feel that it will give delight😌. After 20 breaths, return your breath to normal.
About 5 minutes later, you can begin the practice of lengthened breaths again.
When you feel the least bit tired, return to normal. After several sessions of the practice of lengthened breath, you exhalation and inhalation will grow equal in length. Do not practice long, equal breaths for more than 10 to 20 breaths before returning to normal.
