Cesar Paublini

Performance Coach · Pupilo Founder

Cesar Paublini is the founder of The Lab Gym Sports and the architect behind the Pupilo Athletic System. For over a decade he's built the off-season programs that take baseball players from rehab to ready — quietly working with MLB infielders, catchers, and utility players who needed a coach who understood the position, the language, and the work. Pupilo is that work, in your pocket.

Testimonials

What athletes are saying.

Velocity is up 3 mph and I haven't felt this fresh going into spring in years. The phased approach actually works.

Marcus R.

RHP · College

The video instruction means I never have to guess if I'm doing it right. It's like having a strength coach in my garage.

Javier T.

SS · High School

Bilingual coaching was huge for our team. The whole roster can train in their own language and stay on the same program.
