According to Dinesh Kashikar, a Sri Sri Yoga teacher, we are as young as we feel! Yoga asanas tone up the body, keep our internal organs and the hormonal system in balance, and refreshes the mind and spirit. 

 
 

As age progresses, one should focus on HOW YOU DO rather than how much you can do.

 
 

The basic principle in yoga is the union of the various aspects of our existence such as breath, body and mind. 

Of course, elderly can do yoga asanas - provided they keep some guidelines in mind.

Perhaps a more important question would be:

What kind of asanas should one do as age progresses?

  • Brisk walking and joint movements for warm up
  • Standing Yoga Poses such as Triangle Pose (konasana series) and Standing Spinal Twist (Kati chakrasanas)
  • Sitting Yoga Poses e.g. Butterfly Pose, Cradling (if possible), body rotation, Cat stretch and Child pose (Shishu Asana).
  • Yoga Poses lying on mat. Focus on repetitions rather than holding any posture such as the Cobra Pose (Bhujangasana), the Locust Pose (Shalabhasana) or the Knee to Chin Press (Pawanmuktasana).
  • Yoga nidra is by far the most essential part of any yoga practice, and as age progresses, it becomes even more essential to help assimilate the effect of the asana practice into our system.
