Roger Federer is working hard to reinforce his back. The Swiss Maestro had to skip almost the entire clay court season after being sidelined by his “historical” injury to his back.
Roger is expected to play the entire grass court seasons as he is scheduled in Stuttgart, Halle, and Wimbledon.
The Maestro is posting a video on Twitter with the wording “back at it”.
Maestro’s stuff.
