Customized One-on-One Personal Training

Bye-bye fat - HELLO MUSCLE

"Lean muscle mass naturally decreases with age. If you don’t do anything to replace the muscle loss, it’ll be replaced with fat. Weight training can help you reverse the trend - AT ANY AGE."


Benefits of High Intensity Exercise
"High intensity exercise offers so much more than just improved physical performance. We are just beginning to scratch the surface of what is possible."


Benefits of High Intensity Exercise

These kids know their ABC's...Especially that A stands for APPLIED IRON- proud sponsor of the G.L.O.W. 5K held Saturday night 5/18/19 in Naperville! Thanks to all of the school communities, kids and families who joined us for some exercise, but mostly to raise $ for the Jeanine Nicarico Literacy Fund. It is a wonderful cause and prelim numbers tell us about 1,500 participants pounded the pavement and helped raise $45,000! Humbled that Jeanine's parents expressed their gratitude for our support. We are honored to have been able to be part of such a wonderful event, remembering a beautiful girl and raising funds for the literacy fund in her name. #BuildGoodHealth with APPLIED IRON.

Whether you’re just beginning a fitness regimen or looking to advance or change your current routine, APPLIED IRON has all your strength training needs in a clean, private, distratction-free facility. Our specially-trained, experienced personal trainers are experts who use research-based strength training methodology based on Dr. Doug McGuff’s renowned Body by Science teachings.


Our clients range between busy professionals, young adults, and active seniors of all fitness levels. A typical 30-minute or less session is encouraged 2 times per week, and includes 8-10 different weight resistance exercises of varying intensity on targeted equipment.


No more squeezing in the gym 4-5 times per week with minimal results. With consistent performance alongside the care and the positive support of our expert trainers, clients will benefit by gaining strength and adding muscle mass.


Our proven protocol achieves optimum results while eliminating time consuming work outs that produce little progress. Scientific research has proven committing to strength training practices employed by APPLIED IRON maximizes health and fitness benefits and encourages long term success.

"I found Applied Iron four years ago and am so happy that I made the decision to join. The one-on-one training keeps you focused, and the trainers always encourage you to improve. Routines can be quickly changed based on individual needs, or on how you're feeling on any given day. The training has helped me to improve my core strength, which means no pain after a day of golf or working in the yard. Most importantly, my bone density test results have increased in each of the last 2 years. I am currently 65 years old, and am in the best condition of my life thanks to the dedication of the Applied Iron team of trainers."
