Roger Federer is back in training!
From Roger's twitter:
Trying to be 
man. Back at it!

That's Federer's expert fitness trainer, Pierre Paganini receiving.
Two hours later, Roger posted:
Rarely felt so happy being back on a practice court 

General, looks like Roger is motivated to get back in shape and back playing.
That's an amazing vertical leap for someone halfway through his 35th year after knee surgery.
Fitness trainer Paganini must be testing him.
Also, I think Roger is sending a message to Novak.
The day before Roger sent these tweets, in Novak's press conference after beating Robredo, Novak said this about Federer.
“I hope he [Federer] recovers fast, because we are not used to seeing him injured. He’s very fit, and he plays very well throughout the entire year,”
Respectfully,
masterclass
Roger dares to stare down history. he will not back away from this once in a lifetime challenge.
he believes he has a slam left in him. it keeps him going.
he has fire in the belly.
