Michael Schweiss

Pitching & Hitting Coordinator

Coach Schweiss grew up in Parker, CO where he attended Chaparral High School, graduating in 2008. Following high school, he attended and played baseball at the University of Dallas – a NCAA Division III school in Irving, TX where he was a reliever and a starter for the Crusaders. Schweiss pitched over 200 innings for UD, setting several school records and being named an All-American in 2011.
 

Graduating in May 2012 with a degree in Economics and Finance, Schweiss decided to pursue professional baseball. After rehabbing his arm following an injury his senior season, he was offered a contract to play for the Normal Cornbelters of the Frontier League to play independent professional baseball. Schweiss was a starting pitcher for the Cornbelters from 2013-2016 racking up over 350 innings across four seasons, leading the league in strikeouts in 2015, and setting the franchise record for career wins.
 

Immediately following his playing career, Schweiss was offered the assistant coach position at his alma mater in the Fall of 2016. In four seasons as the Assistant Coach and Recruiting Coordinator, he recruited and coached numerous all-conference and all-region players. Schweiss did a little bit of everything at UD but mostly handled the pitching staff during his time there.
 

Coach Schweiss joined the team at Zero Limits Performance, in May 2020, and now oversees player skill development.

What ZLP Athletes say about Derek

"Very relatable coach that is enjoyable to be around."

Coach Derek grew up in Bastrop, Texas where he attended Cedar Creek High School, graduating in 2014. Following high school, he attended and played baseball at Hendrix College and the University of Dallas - two NCAA Division III schools where he played middle infield.

Coach Derek began working under Christian in 2018. He has continued to educate himself in the industry with specialties in Functional Range Conditioning, Functional Movement Systems, Sturdy Shoulder Solutions, and the NeuroType System.

 

"Neurotyping” refers to utilizing a person’s personality traits to evaluate his/her neurotransmitter dominance and utilize that information to select the best type of training and diet to maximize his/her training results. The Neurotype System is the athlete’s and the coach’s ultimate tool to effectively individualize training methods. It allows the coaches to understand the athlete’s brain dominance and thus know what kind of training will be best suited to optimize results.

Coach Derek serves all levels of ZLP Athletes from Middle School to MLB and has a lead role within our adult training programs.
