So, he and a team began reviewing 22 studies that had investigated the effects of yoga on physical and mental well being in older adults. The yoga programs varied in length from one month to seven months, and duration of sessions ranged from 30 to 90 minutes.
"Based on this study, we can conclude that yoga has great potential to improve important physical and psychological outcomes in older adults. Yoga is a gentle activity that can be modified to suit those with age-related conditions and diseases," Sivaramakrishnan said in a statement.

Compared with other activities yoga improved lower body strength, lower body flexibility and depression.
