Hector Montalvo Angulo is a Spanish level 1 national pistol coach that I met thanks to an invitation to participate in an online competition via WhatsApp during the first COVID lockdown. Among the many things that were shared in that group was this conference he gave at the olympic shooting federation of Valentia (Real Federación Valenciana de Tiro Olímpico). As soon as I started reading it I thought that it had to be published and Hector immediately gave permission.
