But the Spaniard had no complaints as he glided into a news conference on Tuesday ahead of his opening-round match at the Western and Southern Open to discuss what has been a perfect start to the North American hardcourt campaign.
Nadal has already counted two hardcourt wins among his eight titles this season with victories at Indian Wells in March and in Montreal on Sunday.
With the exception of grass courts and an opening-round slip up at Wimbledon, the Spaniard has impressed on all surfaces this season having added to his grand slam collection at the French Open and capturing four of six Masters Series events.
Playing in his first tournament since a shock exit at the All-England Club, Nadal returned to action in Montreal last week and showed he was back to near his best and that his ailing body was ready for the gruelling demands of the North American hardcourt campaign.
Less than 24 hours after Saturday's hard-fought, semi-final win over world number one Novak Djokovic, Nadal, playing with all the conviction and freedom of a man near the peak of his powers, crushed Milos Raonic in front of the Canadian's home crowd to claim his 25th career Masters title.
With eight wins from 11 events, there is speculation that Nadal has finally struck a balance between tournaments and time off that has always proven elusive for the top players.
But the muscular Majorcan laughed off that suggestion saying it was virtually impossible to come up with a foolproof plan simply due to the nature of the sport.
"I will say in a sport like tennis, my feeling is everybody who says, 'I find the perfect schedule,' everybody's lying," Nadal told reporters. "Because in tennis, when you prepare your schedule, you don't know if you will play one match, two, three, four, or five. You can lose in the first round, so the schedule is changing a lot.
"You cannot predict which result you're going to have in the tournament.
"I don't want to be too smart and say I prepared the schedule great and that's why I arrived to Montreal in very good shape. It's not true."
UNFORGIVING SURFACE
What is true is that Nadal is on top of his hardcourt game at the moment.
The U.S. Open has always been the hardest grand slam for Nadal because of its unforgiving surface and timing, spending more time grinding his gears on the pavement than looking like the well-oiled machine he has this season.
Of his 12 grand slam titles only one has come on Flushing Meadow's hardcourts while he has only reached the final on one other occasion.
Some observers have suggested that Nadal is in the best hardcourt form of his career making him one of the red hot favourites to lift the season's final grand slam.
"It's difficult to compare with other seasons," said Nadal, who will join the action in Cincinnati on Wednesday with a second round clash against German qualifier Benjamin Becker. "I only played two tournaments on hard, but it's true that I played well.
"I watched a few matches of Indian Wells and tried to analyze what I really did well there and try to copy a little bit and practice with that goal.
"I played very well in both tournaments. Very happy the way that I played last week, especially last two matches."
Nadal insisted his approach has not changed but Djokovic disagrees.
"He became more aggressive," said Djokovic. "That's where I felt it. Especially on the return in Montreal he was coming closer to the line and he was picking up the ball quite fast.
"So that was different probably comparing to our last matches on hard court but it was still a close one."
