About Our Staff

Jeff Tirrell

Getting in shape is not meant to be a torturous endeavor. There may be a sore muscle or two along the way, but I believe getting fit should be enjoyed, not dreaded. I get to change lives for a living, which is not only a privilege but incredibly fulfilling and rewarding.


I've gained a diverse range of knowledge and experience since entering the fitness profession full time in 2008.  Ranging from workplace conditioning at Toyota, collegiate strength and conditioning at Western Michigan University, powerlifting, bodybuilding, general fitness clients, and working with post rehab and elderly clients.  I've helped clients set state records and compete on the national stage in Powerlifting, run ultra marathons, climb mount Kilimanjaro, or just have more confidence and less aches in their daily life.  


Though I played many sports growing up and was always active I was a chubby and weak kid who started getting bullied in early middle school.  I was able to use weightlifting to change my life and I'm passionate about doing the same for my clients.  More of my Origins story can be read here. I wrestled and played football in High school, competed in bodybuilding from 2004-2008, and powerlifting from 2012-2017 where I accumulated nine top three finishes, two State championships, and two Nationals qualifications. I currently train in Brazilian Jiu Jitsu in my free time, and enjoy mountain biking, hiking, and exploring with my wife and  four kids.

About: About

Amanda Qusarano

Amanda received her certification for personal training through the National Academy of Sports Medicine in February of 2021 and has been a trainer ever since. She has been lifting weights on and off most of her life.
Amanda became a personal trainer with a mission to empower women of all ages through strength training. Weightlifting helps build confidence not just inside the gym, but everywhere in our lives. There are so many women who feel like they can’t or shouldn't lift heavy weights. That is just not true. Women won’t become big and bulk like the covers of bodybuilding magazines from touching a barbell. That type of physique takes A LOT of dedication to training and extreme dieting. What you will gain is the confidence to do things in your daily life that you didn’t think you could before: like carrying your water softener salt without help, carrying your children with ease, lifting heavy items around the house like kitty litter or economy sized laundry soap, carrying in all the groceries in one trip, etc. Plus, you get to live life knowing that you are a total badass cause you can lift heavy weight and look good doing it.
In her spare time Amanda enjoys reading, playing video games, drawing, painting, and falling into hyper focus research on various topics. I am married to my high school sweetheart, rekindled after 16 years. We have 5 cats and 2 dogs.  Amanda went to Linden High School and received my associate in arts from Mott Community College.
