About Me

I’m a sports scientist from the Autonomous University of Madrid, Spain. My main interests are exercise performance, strength training and new technologies. I have a PhD. and two MSc. on High Performance in Sports and i’ve authored several scientific papers on peer-reviewed journals. I’m also an iOS developer, creator of My Jump Lab, a scientifically validated app to measure sports performance, used in more than 100 countries by professional athletes, coaches or researchers.

I've worked as a consultant in elite sports with NBA teams and elite runners, among others. Finally, i give talks on the topic of exercise performance, strength training and new technologies. I have given several talks in International MSc., Symposiums, Congresses or private events in Spain, France, Italy, UK or the USA. Also, i’m the main author of “Strength Training: New Methodological Perspectives”, the first multi-touch sport-sciences iBook in Spanish.
