Sania Mirza was trained by Reynes at his Las Vegas centre after Sania missed India's Fed cup Campaign due to an abdominal injury after winning her first Grand Slam mised doubles at the Australian Open Tennis.
Sania's coach Sven Groeneveld was also there with her during the stint.
"I have enjoyed the training sessions with Sania. I am truly impressed with her athleticism. She has natural athletic ability and has been well coached," Reyes said.
"Professional tennis has become quite physical and will continue to do so. Adding a strength and power to a natural athlete like Sania could certainly improve her tennis game, specially speed, movement and court coverage," he said.
