psicologia & ALTO RENDIMIENTO
Mental Gym Therapy
Soy Sergio Núñez Martínez, psicólogo en Sitges (Barcelona) y online. Cuento con más de 20 años de experiencia en alto rendimiento, psicología del deporte y terapia breve estratégica.
My main goal is to support developing athletes, elite athletes, high-performing professionals, and people going through challenging times in achieving the perfect balance between peak performance and well-being, providing answers to the most dynamic challenges of human behavior.
I start from a fundamental premise: each person is unique, and every process is individual. Through Strategic Brief Therapy, we design a tailored path to help you achieve your goals in the most direct, effective, and lasting way.

Frequently Asked Questions
Coffee for everyone, but no two coffees are the same. At Mental Gym Therapy, there are no standard formulas: we tailor each process to your goals.
We work without rigid labels or stigma, addressing everything from sports performance optimization to more complex difficulties.
We analyze your current situation, the strategies or “solutions” you have tried so far, and why they have not worked, replacing them with effective alternatives. We combine practical tools with the highest standards of scientific rigor.
Sessions will be conducted (except in certain cases) online to accommodate each individual’s circumstances. This way, it doesn’t matter where you are, as we can hold the session via a Google Meet link that you will receive before the session begins.
The first session is informational and free of charge. It will last approximately 20 to 30 minutes, during which we will assess whether I can help you and in what way.
There are some exceptions where an in-person visit may be necessary, either to observe sporting behavior directly, in cases where scientific evidence suggests that psychotherapy is more effective when conducted in person, or when the person simply feels more comfortable being physically present rather than online.
Session durations may vary, but 1 hour will be reserved for you. In the brief therapy model, the most important work happens between sessions. It’s of little use to discuss something during the session if it is not applied in daily life afterward.
At Mental Gym Therapy, we allow a maximum of 10 sessions for meaningful change to take place. If no breakthrough or observable change has occurred after 10 sessions, the therapeutic contract.

As a licensed psychologist registered with the College of Psychologists of Catalonia, I must comply with Articles 38 and 39 of our profession’s code of ethics.
Art. 38: The information that a psychology professional gathers in the course of their practice is subject to confidentiality, which can only be waived with the explicit consent of the client or under legal provisions.
Art. 39: In the informed consent process, it is necessary to inform clients about the limits of confidentiality. In addition to the limits established by law, these include any serious risk posed by the client to themselves, to third parties, or to the professional.
In sports psychology cases, it is important to clarify that confidentiality applies in the same way as in other cases—that is, between the athlete and the psychologist. At no point will information be shared with members of the athlete’s support team (coaches, physiotherapists, strength and conditioning coaches, etc.) without the athlete’s consent, always in accordance with Articles 38 and 39 referred to above.
