Kyrgios shares displeasure after gruelling workout set as comeback from knee surgery continues in Roland Garros race against time

Nick Kyrgios is working hard on a return to tennis following a knee injury that kept him from playing at the Australian Open and many events after that.

Kyrgios was hoping to play at the Australian Open earlier this year but he didn't get to due to a knee injury that needed a small procedure to fix. He's been out since then but hoping for a return as soon as possible and he's actually working on it really hard. He posted an update on social media showing his gruelling workout as he works his way back.

The Wimbledon finalist completed a number of sets in a circuit; doing some taxing cardio on some notorious gym machines like the assault bike, Versa climber, rower, sled and SkiErg ski machine

Check it out below with a very interesting pose from Kyrgios.
