Marca says Pique hasn't been seen on the pitches at Barcelona's training ground, as he has instead been doing specific gym training since Monday.
His main objective now is to fully recover from the pubis and abductor problems he has been suffering since last season, and he is following a personalised plan.
The importance of the games in the run-in during the last campaign meant he couldn't rest and recover well from the problems.
Although he has worked hard in the summer, those injuries haven't gone away and he is now treating them with a special trainer in the gym with the aim of returning to the pitch as soon as possible.
Pique wants to be fully fit for the club's tour of the United States, which starts on July 18. The aim is that next week he will be able to train with the rest of the squad, although it will depend on how he feels.
