Strong, Confident & Successful: How Physical Training Boosts Resilience and Strengthens Your Business

A sales rep joined Eva Rostock's self-defense class to feel safer. Three months later she told her trainer something else had changed: she argued more calmly with colleagues, held salary talks with her manager and closed bigger deals. Rostock, head coach of a self-defense school, says she sees this pattern again and again. In her talk on 14 May 2025 she explains why, and what freelancers can do.

What the talk covers

• Why freelancers need it: you sell yourself first, with no team to fall back on, in constant pitches and negotiations.
• Her explanation of stress: the brain reads uncertainty, fear of failure and fear of rejection as threats and switches the body to alarm. Unlike a predator, an inbox never goes away, so many people stay in alarm mode.
• How physical training helps, in her model: tools first, then rising intensity, then a push to the point of failure, then repeating the same level until it works. The brain learns that it can handle the pressure.
• Resilience as a learnable set of skills such as emotion regulation, impulse control, empathy and the belief that you can solve your problems.

Four quick tools

1. Breathing: a long out-breath, such as four counts in and eight out, or box breathing.
2. Wake up the body before a stressful moment: ten push-ups or moving to a favourite song.
3. Sit upright, which she says clears your voice.
4. A weekly confidence session, even 30 minutes, ideally with a coach or training buddy.

Q&A

Online personal trainers work for accountability, in-person training adapts better. Activities that demand focus, such as heavy lifts, help switch off work thoughts.
