The former Celta Vigo star arrived in south Wales for a modest £2m from Rayo Vallecano in the summer and has started brilliantly, scoring four goals in four Premier League appearances.
It was suggested that the 26-year-old, who had never played outside of Spain, would need to be stronger to succeed in the Premier League.
But, speaking to Spanish newspaper AS, Michu revealed that he would not be pumping weights in the gym because of Swansea's style of football.
He said: "The workouts are similar to what I was doing in Spain because Laudrup more or less the same as he when he was in charge at Getafe or Mallorca.
"It is true that the rivals are more physical. But to play in Swansea you do not need much physical because we want to play it like Barca."
Alongside, Chico Flores, Angel Rangel and Pablo Hernandes, Michu is one four Spanish players currently part of Laudrup's first team.
He added: "We've been called the Swansea Spanish and the Spanish Armada, the usual sort of stuff.
"But much quality has come from our country. Swansea is a family club which was in the third level four or five years ago and is now competing with the best teams in the country and most of the world."
