Meredith Davison

Hi, my name is Meredith! I began experimenting with lifting when COVID hit in 2020. Before lifting, I had been a part of dance and gymnastics for eleven years, starting at just the age of three. The sudden elimination of activity in life made it apparent just how important keeping my body moving is; thus, I began lifting weights to replace the exercise I had been receiving from dance and gymnastics. Over the summer of 2024, I decided to work towards my certification to become a personal trainer because I wanted to share my love for staying active with other people. I have gained a lot of knowledge through my lifting on the best ways to work different muscles. It brightens my day to teach others how to do the same and see them apply what I have taught. I typically include a mix of both strength and muscular endurance training in my lifts to build muscle and maintain strength. Over the years, with a proper training regimen, I have found myself happier and healthier, so I hope to spread that positivity!
