Born in León, Cuesta devoted his early years to tennis, learning from figures such as Nick Bollettieri, Guillermo Vilas, Pete Sampras, and Jim Courier.

[5][6] At a very young age, an injury marred his tennis career, but he kept training with Bollettieri until he asked Cuesta to move to Thailand to open an academy.

[11] In 2012, the Spanish Herpetological Association criticized the TV show La selva en casa, presented by Cuesta.

[12] Later that year, the association notified the government of the Principality of Asturias, who then imposed three fines, worth €11,501, to Cuesta, as well as to the director and producer of the show, Sonia López and Molinos de Viento, respectively.

[24][25] Despite being considered an animal-rights activist,[26] Cuesta declares himself an "anti-animal-rights-activist" (in Spanish: antianimalista), saying that "the animal rights movement should be called 'subsidyism', the art of making money from anywhere.

[35] In July, Cuesta published a video announcing that the ailment "will likely finish me off in the future" and "for seventeen years, I've been saying that life is a marvelous shit.
