Hi iam 21 yrs old female n my height is 5.2 . i want to increase my height . do i have any possiblities ? what methods or exercise can grow my height

High heels: At 21 i believe you have achieved your maximum height unless you alter it artificially. Growth plates are closed which is where bones lengthen as we are young. 62" is a good height for a young woman.

Accept your size: At 21 your growth centers are most likely closed ; no further growth is possible. If your growth centers are open (xray of hand can tell) you might grow some, but most growth centers close at 17 in females so this is unlikely. There is no magic exercise or diet to grow taller.
