According to Argentina's TyC News on July 13th, Beijing time, Argentina's substitute players trained while the starting players got a rest.

According to reports, after defeating Switzerland in extra time to advance to the World Cup semi-finals, the Argentine national team began preparations for their match against England. Local time afternoon, at their training ground in Kansas City, only substitute players and those on the bench participated in training.
Under close monitoring by the team doctor, the only player missing joint training is Nicolás González, whose left ankle injury from being stepped on is still causing him excruciating pain.
At the start of training, while the other players practiced ball control in a confined space, Nicolás González stayed on the sidelines to stretch his injured leg and rest for a few minutes. However, he quickly rejoined the lighter training session.
This time, the starting players were all watching the training from the sidelines. They played for over 120 minutes last night, and the coach let them rest.
The current focus is on restoring the players' fitness and preparing them for the final sprint, as there are only three days left until the next match. The good news is that Romero and Paredes, who were substituted in extra time due to discomfort, are not injured. Defender Romero was replaced by Otamendi, and midfielder Paredes almost walked off the field on one leg, being replaced by José López, but this was simply due to exhaustion and minor injuries, nothing serious.
On the other hand, the team's initial plan is to remain in Kansas City until Monday, when they will train in the morning before departing for Atlanta to compete against England for a place in the final. They will have their first training session in Atlanta on Tuesday, followed by the coach's regular press conference at the Mercedes-Benz Stadium.
