He fell in love with training and fitness through swimming and lifting and continued to lift weights after finishing competitive swimming during his time at college. During all his time lifting weights he always tried to learn as much as he could about all aspects of health and fitness. Dylan eventually helped start a club at South Dakota State University called the Jacked Rabbit Lifting Club, where he served as a club mentor and helped other club members with their training and nutrition to help them reach their goals. After graduating, he competed in a bodybuilding competition in 2022, and learned a lot from the process and is excited to potentially compete again in the future.

Dylan’s main areas of focus have always been athletic performance (Strength and conditioning) and Hypertrophy (Bodybuilding Training). He love working with athletes to improve their sports performance. Hypertrophy training is his personal favorite way to train because of the tons of different exercise selection and variation, as well as the many different training styles that can be used to achieve a similar goal.

In the past, Dylan used weight and fitness training for his own personal success to become an All-State Swimmer in multiple events during my swimming career in high school, as well as compete in a bodybuilding show.
