Tim Holzäpfel

RKC Team Leader

Bio

As a professional officer in the Bundeswehr and a certified personal trainer, I am convinced: With the right mindset, anyone can push their individual boundaries and grow far beyond themselves.

As the founder and owner of CROSS&ROPES®️ – Functional Hardstyle Training, it is clear to me: Physical and mental performance are the keys to a healthy, balanced, and fulfilling life.

My expertise is based on over 25 years of training experience in strength training and military fitness. My focus areas include Hardstyle kettlebell training, strength & conditioning, athletic training, competitive body styling, and nutrition coaching. I share this knowledge in seminars throughout the German-speaking region (Germany, Austria, Switzerland) as well as in 1:1 coaching in Rheinbach near Cologne or online.

I discovered the kettlebell in 2014 during an outdoor training session. After a self-taught introductory phase, I attended the seminars “RKC – Enter the Kettlebell (ETKB)” and “RKC – THE BIG SIX” with Master RKC Pia Scherenberger in 2015. In the following years, I was certified as an RKC instructor by Master RKC Robert Rimoczi in 2016 and as an RKC II instructor by Master RKC Dan John in 2017. Since then, the Hardstyle principles and training philosophy of the RKC have formed the foundation of my work as a coach. In 2023, I was promoted to Team Leader in RKC Germany and I share my knowledge with future kettlebell instructors at the RKC – School of Strength.
