Tanner Larose

Certified Personal Trainer

Tanner’s love for sports and fitness started at a very young age. Having come from a family with a number of professional athletes, Tanner was always very fitness oriented. He grew up playing and participating in a number of different sports such as basketball, baseball, football, and soccer.  Tanner started to accompany his father to the gym at the age of 12 in hopes of enhancing his performance in sport. He has been training and challenging himself ever since. After the first visit he knew he eventually wanted to make a living in fitness. In high school Tanner played baseball and basketball and was awarded “most athletic” in school. It was during high school that he started to uncover a real passion… powerlifting . From the age of 15 to 22, Tanner and his father competed in powerlifting meets. Throughout his years in powerlifting he was exposed to a variety of training techniques from top tier athletes from around the World and USA, including a two time world bench press champion of whom Tanner had the ability to work and train with. Tanner is a two-time state bench press champion and a national qualifier.
