Growing up in Plano, I have seen the entire area of Kendall County grow over the last 20 years.  I graduated from Plano High School in 1990 and left for U.S. Army boot camp a month after graduation.  I spent 12 years in the Army where the majority of that time was on a Special Forces A Team (Green Berets).  In 12 years of service I felt I had been involved in the best physical fitness training available.  From running marathons up the mountains in Alaska to “smoke Sessions” in Ranger Training,  to Special Forces Assessment and Selection,  I thought I was in the best shape of my life.  After getting out of the military, I became a police officer in the Kendall County area.  I spent 5 years as an officer where during that time I spent several years as a member of the Kendall County Special Response Team.  Again, being involved in the police training and the SRT I worked out on a daily basis and was always among top percentage of officers when it came to physical fitness.  I continually worked out with the same routine that most people who read the muscle magazines and talk to regulars at the local gym who think that sitting in a gym for hours at a time working single joint movements for 45 minutes and then running or working on the elliptical for another 45 minutes thinking I was in great shape and could handle any situation handed to me.   After 5 years of Law Enforcement service I decided to get into security contracting overseas in hostile areas.   Within the first 2 months of working as a contractor I found out how unconditioned  I really was.   I started training with a couple guys that had 15+ years of age on me and had been doing CrossFit for a couple years.  I was run into the ground by these guys that I considered to be out of their prime.  After that I was hooked on CrossFit.

I have been doing CrossFit for over 5 years now and I am by far in better shape than any other time in my life.  I brought this training back home to my family and friends and so far all have enjoyed it and have benefited from it.  I have been training and coaching military, police and civilian personnel in many different facets from rifle/pistol fundamentals to Small Unit Tactics to basic situational awareness/self defense courses for the last 15 years.  I realized that with the knowledge I had gained in conducting a CrossFit program, I could bring this experience back to the Kendall County area and help the people in the area that I grew up benefit from this high intensity, results driven exercise program the same way my family and friends have.  For anyone that has the motivation and drive to be the healthiest they have ever been, I look forward to assisting you in obtaining your goals.

Being from the small town of Sandwich, and growing up with 5 siblings, I was a pretty active kid.  Although I never participated in any sports, (unless cheerleading counts) I was able to remain in very good shape.  That was true until I became a wife and a mom of our two daughters. I, like a lot of people do, let myself go. I didn’t work out consistently and only focused on being a certain weight.  To people who looked at me, I didn’t appear overweight, however, I met the profile of a “skinny fat person” to a tee.  I would say I had zero strength and needed to get fit, but could never find a workout regimen I wanted to stick with for very long…  until CrossFit.

 I was introduced to CrossFit by my husband, Dave in 2009. Dave has always been into fitness – working out regularly and staying in very good shape. I always thought he looked great. During one of his first trips overseas, he started doing the CrossFit program along with changing up his nutrition.  He came home with a completely different look… not only was he really fit, he was ripped!  I have to say this is what really inspired me to get involved. I decided to give it a try and we put together a small gym in our basement. After doing CrossFit for several weeks, I was already seeing changes in my appearance, and my clothes were fitting better.  I remember starting on ring rows and within a couple of months I had progressed to unassisted pull-ups.  Seeing the progress and overcoming the challenging workouts soon became addicting. While Dave would go overseas, I handled running our small basement gym with about 7 of our friends and family. We loved CrossFit so much and we just knew everyone else would too.  We wanted to share our passion with everyone so we opened up Bare Bones.  Over the past few years we have developed a pretty awesome community.  We’ve seen amazing progress and transformations from our Athletes and have made many friends along the way! We can honestly say we LOVE what we do!  As your coach, not only do I want to help you reach your fitness goals, I want to help you make a lifestyle change by finding your inner confidence and strength.  CrossFit is hard both physically and mentally, but it is worth every bit of effort you put into it.

I have always considered myself pretty physically fit but I was introduced to CrossFit in March of 2012. Wow!! It totally changed my perspective on fitness. Instantly I was hooked! I wish I had Crossfit in my life back in high school and college while playing sports. I came to Bare Bones in November of 2012 as an athlete and what a great time it has been with like-minded people with similar fitness goals. I came on staff in May of 2013 as a L1 coach. I received my Crossfit Rowing Certification in February 2014. Yep! I am a rowing freak! I am always eager to learn more and further my knowledge in lifts or Crossfit in general. CrossFit has totally changed my life.

“My name is Mary Jo Prusko and I grew up in Carol Stream, IL.  I earned my AA and AS from the College of DuPage and then went to Northeastern Illinois University where I majored in mathematics and secondary education.  After I started teaching I went to DePaul University to get my masters in Mathematics Education.  For the past 17 years I have taught math at both the high school and university level.
I grew up playing soccer (on the boys team because they didn’t have girls teams when I was little) up until high school.  Then I stopped and my only fitness was in gym class during high school.  I didn’t really work out until I left my parents house and moved to Montgomery. I was used to living in a house with 6 other people, so when I moved out I needed something to do because it was so weird being in an empty house.  So I decided to join a gym.  I joined a traditional gym and at first started on the elliptical machine and the weight machines.  I stayed away from the free weight section because that was where people looked like they knew what they were doing and I had no idea how to lift weights.  My younger brother then started helping me and gave me a traditional upper body/lower body day workout to do using the free weights.  Back in May of 2012, a friend told me about CrossFit.  I always wanted to try a boot camp style class and thought I was in shape, so I did the first workout.  I very quickly realized I was not in shape; however, I was hooked.  Six months later I was going to my first competition, which I have since become addicted to doing.  I earned my L1 certificate in July 2014.  In the past year have added a mobility certificate, gymnastics certificate, and most recently the CrossFit Kids certificate.
I recently turned 40, and I realized that I am probably in the best shape of my life.  I wish CrossFit had been around when I was younger, because I would have loved it.  I hope to share my love of this sport with everyone that I coach.  I am really looking forward to working with the kids the most.  It will be a great opportunity to instill good skills and habits early in their life.  And it will be amazing to see them grow.”

Thomas Kraus | M.S., M.A., NBPTS, C.S.C.S, USAW, National Level Olympic Weightlifting Coach

I am a 17 year National Board Certified physical education teacher and coach at West Aurora High School in Aurora, IL. I played many sports growing up including football and wrestling. In college, I played rugby for several years before concentrating on Olympic weightlifting.

My first coach was Marty Schnorf of the Charleston Weightlifting Club, Charleston, IL. After graduating from Eastern Illinois University, I started training with Olympic level coach Mike Gattone, head coach of Sayre Park Weightlifting Club.

In, 1998 I started the Aurora Weightlifting Club (AWC). In the 8 years I coached the AWC, I had many schoolage national champions, junior national place winners, and schoolage Pan American place winners. Most notable of the AWC athletes was Matt Lee – two-time schoolage and Pan American champion. Matt eventually wrestled at the University of Illinois.

When I started my family, I discontinued actively coaching Olympic weightlifting. Professionally, I concentrated on my teaching and strength coaching responsibilities.

I now am back in the game chartering the Northwestern Illinois Weightlifting Club (NIWC). With hard work and planning, the NIWC will experience the same success as the Aurora Weightlifting Club.

I have four children Nate, Jackie, Daniel, and Nikki. I have been married to Caroline for 12 years. My wife and family give me more strength and power than weightlifting ever could.
