The story
No running back coach, no speed coach. I taught myself everything: from videos, from mistakes, from years of figuring it out. In 2025 I finished the season as ELF champion. K2 is the shortcut I never had.
My storyProof
"Squat max from 100 to 120 kg, bench from 80 to 100 kg, and my 40-yard time from 4.9-5.0 to 4.8-4.7."
"I was not only able to maintain my speed and explosiveness during the season but even improve them. He knows exactly what it takes to dominate on the field."
"More power, better endurance, and above all, I became noticeably faster. My change of direction has also become much smoother."
"Prepared optimally for the season even in a very short time, and stayed fit and fast throughout the season. Open questions are answered quickly."
