I'm the author of the CoachingVB.com blog and developer of the Volleyball Coaching Wizards project. I've coached from juniors up to professional teams, in the US and Europe, both men and women.
In August of 2019 I spent almost three weeks with Hungarian men's professional team FINO Kaposvar during their pre-season. Ruben Wolochin, the Head Coach, is very well respected among professional coaches. This was the start of his first season in Hungary after having previously coached in Germany, Finland, and Spain, along with his native Argentina.
While I was with Ruben and the team, I recorded basically every practice session. Now you can access that material, plus additional content.
