Studied framework: Relentless operates on the MAC framework, the only studied mental framework for athletes. M - Mindfulness: Noticing your thoughts, emotions, and feelings. Not making any changes. A - Acceptance: Allowing yourself to think through the negative ones without spiraling. C - Commitment: Directing those thoughts so that you are prepared in any situation. How it works: Relentless is backed by sports psychology designed to walk you through short, guided lessons with the aim of improving your mental ability in competitions. A higher mental ability has been proven to lead to higher and more consistent results across competitions.
