App Description
Relentless is a mental training and performance app built specifically for competitive athletes. This is not ‘motivation,’ it’s an actual framework so that even when the motivation fades, the tools are available to maximize performance.
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 works with sports psychology professionals 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.
Features:
“Workout of the Day” guided by a sports psychologist
Full library of lessons to practice each aspect of the MAC framework
Built-in journal that helps you keep track of your mentality surrounding competitions
0-100 trackers for consistency across each aspect of the MAC framework
Profile that stores your next competition date to keep you focused on the goal
