Star Indian men’s doubles pair of Satwiksairaj Rankireddy and Chirag Shetty has “cracked” the service variation challenge and is focussing on “comprehensive physical and mental conditioning” to ensure peak performance at the upcoming Paris Olympics.

Satwik, 23, and Chirag, 26, have been troubled by the wide variations of tumble, spin and wide serves that their opponents, mainly the Koreans and Indonesians, have employed against them during the recent tournaments. Chirag said they have addressed the “new challenge” and remains confident of negotiating it during the Paris Games.
