COR High School Strength Training Philosophy

Nowadays, high school students sit, a lot! Whether it is during school, SAT preparation, or violin lessons. Even athletes sit too much, which can contribute to poor posture, injury risk, and reduced performance. To combat these issues, professionally designed resistance training programs are needed. At COR, we’ve worked with thousands of clients, ranging for Olympic athletes to general fitness. This diverse knowledge helps us create programs with performance and long-term health in mind. These classes focus on proper biomechanics, education, and much more!

Coach Michael Vaandering

Michael Vaandering graduated from the University of Michigan School of Kinesiology with a B.S. in Physical Education and a minor in Health Education. He is a Certified Personal Trainer with the American College of Sports Medicine (ACSM). Michael grew up on the west side of Michigan, where he competed on his high school’s water polo team as well as the swimming and diving team. As a springboard diver, he earned all-state and all-american status. During his junior and senior years, Michael used his experiences on the diving board to informally mentor the middle school diving team, including occasionally taking the role of interim coach. During his college career, he was a member of the University of Michigan Men’s Swimming and Diving Team where he helped his team toward NCAA and BIG 10 Championships. During that time he was also a coach for the local rock climbing team. He used these outlets to apply his knowledge of the underlying biomechanical principles involved in motor movement and performance to gain an edge over competitors and improve the strength and efficiency of his climbers. Michael has also been published in the International Journal of Case Studies as well as the Journal of School Health for his research into the connection between physical activity and cognition. As a supporter of lifelong sports and the many benefits that accompany them, Michael spends much of his time in such activities as tennis, squash, rock climbing, hiking, and swimming.
