CARDISAVAGE

I’ve always had an athletic background and a martial arts interest. I started with karate in my youth. I started my MMA Career in 2012, I began train...ing out of Lowell Massachusetts with South Cambodian Kun Khmer which shares the same roots as Muay Thai. During that same time in 2012 I was training Jiu Jitsu under the same gym. I moved between states in my mid 20s looking for fight teams to join. I trained at multiple fight gyms in Vermont, Florida, Massachusetts and New Hampshire. My MMA bouts have taken place in the state of New York, Vermont, Maine and New Hampshire. I have trained in multiple fight styles, my favorite style of Martial Art is Muay Thai/ Kickboxing. I am known as a striker in the Octagon. I’m interested in helping people improve their fitness as a 9Round Trainer. I know great form and a regular fitness regimen will bring maximum fitness results for the members. As a 9Round Trainer and a Fighter. I establish myself as a well-rounded advocate of this type of fitness conditioning.Naturally Kickboxing became my style and choice of fight training and fitness.

SARGE

Hi, I’m Genesee “Gen” Schaufus aka Sarge. Fitness has always been an important part of my life. It started with gymnastics, dance, and cheerleading in... my youth. I joined the Army shortly after high school which kept me quite active with 4-6 mile runs, 12 mile ruck marches and repelling out of helicopters. Now that I’m out of the Army, I’ve continued my fitness journey but now my family often comes with. You might see us out running, biking, hiking or paddle boarding but 9Round is the workout I do for me. I LOVE it! It’s fun, fast and effective. I became a trainer at 9Round because I want to uplift and encourage others while they reach their goals. Do you need a cheerleader making your workout fun? I’ve got you covered. Do you need some extra motivation to ensure you get your workouts worth? I’ve got you covered there too. I’ll pull a little of my Army Sergeant days out to keep you motivated (just a little). My #1 goal though, is to ensure you love your 9Round workouts as much as I do. I can’t wait to see you in the gym!
