In their own words.

I know Marian's work from my own training. Him working with parents of young players makes sense to me - most of the mistakes that catch up with a player later are made in the years he's growing fastest.

Martin Fehérváry, NHL player

Nothing was wrong when I started. My parents and I simply decided that club football training on its own wasn't enough, and when injuries came later, we worked through them with step-by-step rehab. What changed most is my overall strength, stability and explosiveness, plus the one thing every footballer needs: speed. I'd recommend it to any young athlete who wants to improve, and to anyone coming back from an injury.

Miroslav Puliš, youth footballer

Before we started I had constant knee and shoulder pain and no real trust in my own body. The pain eased step by step, the bad habits went, and once nothing hurt I could finally train flat out, and that's when I started improving fast. I kept coming because I trusted him and could see the results. He'll explain something three times without ever making you feel stupid.

Matúš Hauskrecht, youth athlete

I wanted to cover the things there's never time for at club training: explosiveness, quick changes of direction and jumping, which handball demands most. The progress showed in my acceleration over short distances and in changing direction on feints, which became my strength. I started getting above taller defenders in the air. I'd recommend it to any athlete who wants to improve the sport-specific movements that team training doesn't emphasise.

Šimon Hauskrecht, youth handball player

Nothing was wrong; I had no clear structure to the physical training behind my golf swing. I roughly knew which exercises to do, not how often. Now I know exactly what to do, and every session targets what the swing needs: core, glutes, hips and shoulders, plus rotational power, explosiveness and stability. I'd recommend it to any young athlete who is serious about their sport.
