GAVIN RENTSCHLER

My name is Gavin Rentschler and I was born in Indiana. I grew up in a large family and have 8 other siblings! I moved to Florida in 2017 to pursue a fitness degree. I graduated from Southeastern University in Lakeland, FL with a degree of Kinesiology exercise performance. I have been a professional trainer for four years and continue to train clients to help increase their strength performance, muscle, agility and plyometrics, while preventing injuries.

When I am not training, I love to spend time with my fiancé and other family/friends.

I believe to approach everyday with a purpose. Having the right attitude, this can fuel our purpose for powerful success in fitness. Don’t just go through the motions, work diligently in everything you do.
