Athletes on MindSize

In their
words.

MindSize has everything you need to deal with the pressures of performing and competing at a high level. These teachings have shown me how to effortlessly reach flow states and be fully immersed in every moment.

He has opened so many pathways in my mental capabilities to push further on an athletic front. He highlights your strengths to lift and bring balance to the weaker aspects, which brings inner calm.

Reactivity under pressure
External distractions
Aversion to training

Who this is
not for.

The program is specific. Being clear about who it will not serve is part of being clear about what it is.

Athletes not in active training or competition
The skills develop in context. Without a training practice that involves real stakes — sessions, competition, performance — the method has nowhere to land. The program is not a conceptual framework. It is a training system.
Anyone seeking mental health support
This is performance training, not therapy. Anxiety, depression, and trauma require a qualified mental health professional. If that is your situation, this program is not the right resource.
Anyone looking for motivation, strategies, or mindset frameworks
The method does not offer beliefs to adopt, tactics to apply, or heuristics to carry into competition. It trains specific attentional capacities through daily practice. That is the whole of it.

The method

Three skills.
Trained.

MindSize trains three foundational mental skills. They are not strategies or mindsets. They are capacities, developed through structured practice, that transfer directly into competition.

i.

Concentration.

The ability to focus on what you choose, when you choose it, for as long as the moment requires. Not forced attention. Trained attention.

ii.

Clarity.

The ability to track your experience in real time. Sensation, thought, and emotion become readable rather than disruptive. Decisions sharpen.

iii.

Coolness.

The ability to allow experience to move through you without resistance. Technically: equanimity — not detachment, but full contact with performance without reactivity pulling you off course.

The program

Eight weeks,
built in sequence.

Each module develops a specific skill. Each prepares the ground for the next. The program is entirely self-paced, available on any device, with lifetime access.

i. Foundations
ii. See Hear Feel
iii. Restful States

Questions

Common
questions.

The method works across sports. Concentration, Clarity, and Coolness are not sport-specific. They apply wherever performance depends on a trained mental state. Current participants include tennis players, swimmers, cyclists, martial artists, and team sport athletes.

No. The program begins at the foundations and builds systematically. No prior practice is assumed. Athletes with existing mindfulness experience will find the framework integrates cleanly with what they already know.

Sessions range from 15 to 30 minutes. The program is entirely self-paced. There are no deadlines, no expiry, and no required schedule.

The core program has no live classes. Everything is on-demand and accessible at any time on any device. The included group coaching component — live-streamed sessions and monthly calls — is hosted on the Unified Mindfulness platform. Login details for both are provided immediately after enrollment.

Thirty days to try the program. If you are not satisfied for any reason, a full refund. No questions asked. To request a refund, contact support at unified.ladesk.com.

Lifetime access to all program materials. Updates and additions to the curriculum are included.

Sports psychology typically works through cognitive strategies, reframing, and mental rehearsal. Those are tools for managing your mental state. MindSize does something different: it trains the underlying attentional capacities themselves. Rather than giving you strategies to apply under pressure, it develops the ability to direct attention precisely, read your experience clearly, and allow difficult sensations without resistance. These are trainable skills, not coping mechanisms. They transfer across sports, conditions, and high-stakes moments because they are grounded in how attention itself works.
