About Us

We believe everyone is an athlete

Winning Mentality Fitness is a private performance gym in South San Francisco, founded by two coaches who believe training should be specific, technical, and earned.

The Coaches

Who you train with

Brandon Woo, Co-Founder, Performance Coach

Brandon Woo

Co-Founder, Performance Coach

Brandon builds athletes from the ground up. His work focuses on rotational power and velocity development, and he is the coach athletes come to when they want measurable output on the mound or in the box. He assesses first, coaches the details hard, and holds athletes to the standard they set for themselves.

Angus Lee, Co-Founder, Performance Coach

Angus Lee

Co-Founder, Performance Coach

Angus specializes in movement quality, mobility, and golf performance. He translates swing mechanics into training that the body can actually repeat, blending strength work with the mobility and sequencing golfers need. His sessions are technical, patient, and relentless about clean movement.

Philosophy

How we coach

Three rules shape every session we run, from a first-time client to a college athlete in an offseason block.

01

Assess, then train

We never guess. Every athlete gets screened, and the plan comes from what we find, not from what worked for someone else.

02

Train the sport, not the machine

Strength matters when it transfers. We build patterns that show up in your swing, your throw, and your first step.

03

Standards over hype

Progress comes from consistent work and honest feedback. We coach the reps in front of us and track what changes.

The Facility
