School of Strength Training System

What makes our program so different? The main principle is that we train full body movements and not muscle groups, our body is a machine and should be trained as a unit. Basic kettlebell exercises are the biggest and most athletic movements in existence. These are the best exercises to give a complete package of loaded movements that stress the whole body in exactly the patterns that get used in sports and in life.  

We use a Kettlebell Based training system.  We always teach the basic kettlebell lifts first in our teaching progressions.  That being said, every Kettlebell lift has a matching Barbell lift that you will be able to learn if you so desire.  There is no other gym in the country that lifts both Kettlebells and Barbells at a higher level than THE SCHOOL OF STRENGTH!!!

Why Do Kettlebells?

Awesome School of Strength Testimonial!!!

Here is my testimony to Kettlebell training.

It's been almost four years since I started using the Kettlebell as my main source of training.  Before I trained I was overweight, I started exercising in my living room with DVD's by Jillian Michaels, and finally got the courage to leave my house.  I trained in Muay Thai and boxing, became a kickboxing instructor, ran a half marathon and decided to body build.  I stopped running, focused on body building and cut a lot of cardio in order to bulk up with mass.  I attended my first Kettlebell class three years ago and after the first set of swings I thought I was going to vomit.  I realized the lack of cardio endurance I lost while lifting and I didn't believe I would survive my first class.  The only problem was I was addicted after one class.  I joined The School of Strength and trained hard. 

 Through my training at The School of Strength I became fitter, leaner and more defined then before. I love Kettlebell training because it's similar to boxing; the strikes vs. snatch, the breath is the same, the tension and relaxation and the discipline/technique. I was able to run a half marathon with my mother (her first) without running more than five miles prior.  I completed the Spartan Sprint and climbed a 20' muddy rope, jumped six foot walls and I'm running the Spartan Super in Chicago. I couldn't have climbed that rope, scaled those walls or ran without the Kettlebell training.   Last weekend I ran six miles without running a single mile in five weeks.  Kettlebell training offers you the ability to not only increase your strength and endurance but also give you the strength, endurance and mental toughness to train in another sport.  Kettlebell training also helps with life tasks; carrying bags of salt, carrying a 75 pound injured child, painting everyday for a week and a half, and so much more.  Getting my RKC is one of my most favorite fitness goals I've achieved.  If you are tired of knee injuries, high impact exercise and want something fast and effective then train with us.

Thank you,
Jennifer Sherlock

Kathie Allen Our First 90 Day Challenge Winner

Kathie Allen is our first winner of the 90 Day Challenge.  Kathie lost 34 inches in 90 Days and 20.6 pounds.  Kathie attends classes on Monday, Wednesday & Friday at 5:15am and sometimes the 6:00pm Kettlebell Insanity class.  If you see Kathie give her a big congratulations and encouraging words as she continues her journey to a healthy life.   

Why did you start Kettlebell Boot Camp?

My daughter, Aimee Garner, started boot camp last June.  She encouraged me to start coming.  The thought of getting up at 4:30am, exercise and then work all day seemed impossible.  She kept pushing me and I seen what it did for her.  So, I made the commitment to join.  I am glad I did!


What made you decide to try the 90 Day Challenge?

By the end of December, I had gained so much weight and was sick of myself.  Having kettlebells and the challenge to help me lose weight was like the two pieces of the puzzle that I was missing.  I have tried a lot of things that helped for a short time or not at all.   I always wanted a quick fix.  All anybody needs is exercise, portion control, good food choices, and a lot of patience!  What a simple concept.


What changes have you seen since starting the challenge?

I have lost weight as well as inches and I am firming up.  I have more energy and getting up at 4:30, 2-3 times a week does not even faze me now.  I am either at boot camp at 5:15, or 6:00 Monday, Wednesday and Friday or Kettlebell Extreme (Insanity) on Monday Nights. 


Who/What is your inspiration to keep coming back?

My daughter, Aimee.  She just wants a healthy mom and she always has my back.  Aimee made a chart for me to write down everything that I eat and the calorie count.  I have done this since January 1.  It keeps me mindful of what I have ate through the day.  Also, I have appreciated the support from many of my kettlebell friends, Jennifer & George especially.  Thanks!


What is your favorite thing about the School of Strength and/or 90 Day Challenge?

I never knew how much fun lifting weights could be.  I like that I am getting stronger and can do things that I could not do just four months ago (going up four flights of stairs at work and not feeling like I am going to have a heart attack when I get to the top).


What are your long term goals?

I plan on getting all of my excess weight off and keep it off, and continue making healthy food choices forever.  When I am in the Kettlebell Extreme (Insanity) class, I want to eventually graduate from the modified exercise and do the real deal (jumping jacks).


What advice would you give to someone just starting or thinking about getting started at THE School of Strength and/or 90 Day Challenge?

Give both a chance.  There is always someone to support you, show you the right way.  As you lose weight, lifting helps you firm up.  It is hard work, but it pays off in the long run and you have fun along the way.  You can see results soon which helps keep you going.

At THE School of Strength we have not only the best members, but the best coaches in the country.  Here is a very motivating email I received from one of our instructors George Boots.  Please read:
Coach Mills-

 I want to take the time to discuss my recent physical I received at the Fire Department this year.  It was my best physical to date!! I weighed in at just over 180lbs and was asked on two separate occasions if I was a runner.  When I stated “no” the x-ray tech doing my chest x-ray said “you have long lungs”.  I didn’t even know “long lungs” existed!  She stated they normally see that attribute in runners.  My reply was simple “I don’t run a lot, but I do Kettlebell Training”.   After that I spent time with the N.P. and she reviewed my blood work with me and remarked how it was outstanding.  My HDL (Healthy Cholesterol) went up 6 points and my LDL (Lethal) went down.  My fasting blood sugar was 80 (and I didn’t fast!) and my b.p. was 100/64 with a resting heart rate of 54.  She asked me what I was doing and I told her “I do kettlebell training”.  My spirometer test (breathing) was off the charts and she remarked that I must be a runner.  At the end she said to “keep doing what you are doing, it is working”.  Again, I train with Kettlebells.  Nothing fancy or elaborate.  Simply Sinister as Pavel would say.

 Coach, I think it is important that I share this information so people know this training provides true and real benefits that you don’t always “see” in our training system.  I do train hard and I watch my diet, but I still have ice cream and pizza.  I just do it in moderation, so I can enjoy it without the regret that comes with it.  I work on my breathing while in class and I constantly try and push myself to be better and stronger.  I am not worried about keeping up with the next guy, I am worried about keeping up with me! 

 With the supplements that I use through Beverly International and the training I receive at your facility I have raised the bar for my own physical health in the areas I don’t physically see! 

Remember I once weighed 240lbs and now I am a stronger and healthier person at 180.  Please share this with our membership as you see fit.  Our program WORKS! Period, end of story!  YOU GET RESULTS!

Meet Andrew

Here is another story of one of our 5:15 a.m. kettlebell members!  We would love to hear what changes kettlebell bootcamps and THE School of Strength has helped you achieve!

Why did you start Kettlebell Boot Camp?
                I had just finished P90X and wanted something that was strength-based, but different than a gym membership. A friend of mine that I play basketball with (and is one of the fittest guys I know) did kettlebells so I thought I’d give it a try.
What changes have you seen since starting?
                Although P90X was good, it did little for me compared to kettlebells. I have lost an additional 10-12 pounds and made tremendous strength gains. I have dropped a couple of inches off of my waistline, too. Mostly it is the strength gains that I notice. I have run a couple of obstacle course races, a half-marathon, and participated in a GoRuck Light since joining THE School of Strength. At OCRs I can tell the difference in my ability to pull myself up and over a wall without help. I PR’d in the half-marathon, besting my time from when I was in college by 5 minutes. At the GoRuck Light I carried a backpack (ruck) for 6 hours with 45 pounds of bricks in it. I ended the event carrying a sandbag the entire length of the Indy canal, followed by a 100-yard fireman carry of a 205-pound guy with his weighted ruck on too. Here’s a picture:

Who/what is your inspiration to keep coming back?
                First and foremost it’s my friends at 5:15. They are positive and challenge me to work harder than I would alone. In addition, I feel great and look better and better all the time, so who wants to give that up???
What is your favorite WOD? (Workout of the Day)
                I like the WODs that have a time limit and a goal for repetitions. It is never easy to get all of the workout in under the time limit, but the feeling of accomplishment is awesome.
What is your favorite part of THE School of Strength?
                The attitude of the people at THE School of Strength is the best part. From Marty on down, everyone there wants to be fit, do it the right way through hard work, and have fun in the process.
What are your long term goals?
                There aren’t any weight goals or event goals in my plans. My goal is to continue being active for the rest of my life so I can model a healthy lifestyle to my daughters.
What advice would you give someone just starting out or thinking about getting started?
                Take it one exercise at a time. You’ll get tired, try to finish. If you make a habit of pushing through the tired feeling, you’ll continue to do it. If you make a habit of quitting, you’ll continue to do it.

Meet School of Strength Member Ellyn

THE School of Strength prides itself on helping our Kettlebell Boot Camp members become stronger and healthier.  We would like to share stories of our members with you. 

 Meet Ellyn! 
I have been doing Kettle Bells on and off over the past couple of years.  This is my story….

        I remember the first two weeks when I started kettle bells and just could not believe how SORE I was.  I think every muscle group hurt BUT with going to the class consistently each week and stretching just a little before and after class made most of the aches go away.   Initially, I was afraid to try the more difficult moves because of previous injuries to my shoulder, knee and foot but Marty and I came up with a plan.  I spoke with him about my concerns and he helped me modify my work-out to meet MY needs.   I know what exercises to do if I have to modify and I still get a great work-out just like everyone else!  Marty has been such a wonderful coach and inspiration to me.  His encouragement to do my best keeps me going!!  Also, on a more personal note… I was diagnosed with Type II Diabetes three years ago.  Initially I was on medication until I started exercising and taking better control of my diet.  I have not been on medication for over two years now and the doctor attributes most of this to working out with kettle bells.   Recently had blood work drawn and everything that had been high or borderline came back normal.  I could not believe it!  My Diabetes is completely under control and all levels are great!   Many thanks to Marty and Scott to helping me be the best I can be!

Basic Training Student Question

There was a question regarding the “Basic Training” Course.  The question was “How new is new? Are you including those just beginning or if we have been coming to the evening class?”

The School of Strength wants everyone to be successful and feel confident in yourself and the training you are receiving.  If you are a member from the previous session and you still do not feel confident with certain techniques then please feel free to join the “Basic Training” group.  All of the coaches want you to feel confident and avoid any injuries due to improper form.  The new Fall members will attend 30 days of “Basic Training” separate from the advanced members but you will still complete the same workout.  The “Basic Training” classes are Monday, Wednesday, and Friday 5:15am-6am and Monday and Wednesday 6:30pm-7:30pm.  

Please if you have further questions don’t be afraid to ask!  We want you to be a SUCCESS at The School of Strength!!

Advanced Kettlebell Video


Group kettlebell training is addictive!  You may get hooked if you try a kettlebell session. You may never go back to slow boring aerobics or commercial gyms again!  Our Bootcamp combines kettlebells and many other functional training methods in circuits that give you strength, cardio conditioning, muscle tone and fat loss all in one workout!

Welcome to the School of Strength Kettlebell Bootcamp!

We Specialize in Teaching the Russian Kettlebell System For a Leaner, Stronger, Healthier, Better Body.

We are Indy's only Kettlebell Bootcamp led by the Southside’s only RKC Certified Kettlebell Instructor.  Coach Marty Mills is currently the #1 ranked kettlebell instructor in the country.  Check out his current ranking on first class personal instruction from one of the nation's top kettlebell strength and conditioning coaches.

Are you ready to lose fat, build muscle, or take your sports performance to the next level? 

No other training tool works the ENTIRE BODY and EVERY PERFORMANCE SYSTEM of the human body like the kettlebell. Within a 60 minute workout you can build muscle, burn fat, increase flexibility, increase tendon and ligament strength to prevent or rehabilitate injury, increase your VO2 max, as well as maximize speed and explosive strength.

Once the hard-kept secret of elite athletes, special forces and 'manly' men, the kettlebell is now becoming the preferred tool for men, women and athletes who are tired of not seeing results—and who demand exceptional physical performance! Let Coach Mills show you the way.


MEN, Pavel says “kettlebells melt fat without the dishonor of aerobics."  High repetition kettlebell training is an aerobic workout with muscle building effects. If you are overweight, you will lean out. If you are skinny, you will build up. The Russian kettlebell is a powerful tool for fixing your body composition, whichever way it needs fixing.  No need to do aerobics or slow boring cardio anymore.  Kettlebells will make you feel like a man.

Kettlebells won’t create big bulky muscles, unless you are a man who is training hard and heavy and that is what you are looking for.  Kettlebells make a man as strong as they look, you will LOOK STRONG and you will BE STRONG.  You will burn body fat, give your muscles definition, strengthen tendons and ligaments and create “real world” functional strength that will improve the performance of everything you do.

Women, Dare to Be Strong AND Beautiful!

Women have you always wanted to see what "real" strength training would do for your body but were afraid to try?  Our goal is to melt the fat off of your body, while strengthening the muscles and bones (the type of strength you need to promote overall health and fight the effects of aging). 

Kettlebell training builds strength (which tones muscles) and provides an amazing cardio workout. 60 minutes of training 3 days per week will absolutely CHANGE YOUR LIFE AND YOUR BODY!

The Russian Kettlebell Gives You Faster Fat Loss, with More Rapid Gains in Strength, Speed and Endurance Than Any Other Exercise Tool on the Planet!

Many people believe they must separate their workouts into strength training, flexibility, cardio and core conditioning. In kettlebell training this is not true because kettlebells combine all these components of fitness in one challenging workout.  For people who want their training all in one, it's by far the best bang for your buck.  Rather than do an hour of aerobics, and an hour of resistance, you can get it all done in one hour or less with kettlebells.  Just think, in less than 60 minutes you could have the most demanding, fun, and beneficial workout of your life.

Amazing School of Strength Transformation

Some of you will recognize the man at the bottom as Charlie, he is one of the assistant Kettlebell Bootcamp instructors.  I'm sure most of you don't know the amazing transformation he made through hard work, consistency, and dedication to the program.  The top picture was taken in April 2009.  The bottom was taken August 2011 right before Charlie went off to UINDY.  Charlie is one of the greatest strength athletes to come through Center Grove.  He did not accomplish this through natural God given talent.  He did it through simple good old fashioned hard work!  Charlie is an example to all of us that if you want something bad enough it's only a matter of time.  Set a goal, work hard, be intense, be consistent, and be patient.  You can and will achieve your goal!

Passionate, Hard Worker

Coach Marty Mills is a very valuable mentor for me as a strength coach. His system of developing functional athletes is second to none. The time that I have spent observing and talking with Marty regarding all areas of strength training have helped me to develop a coaching philosophy that brings out the most in ALL athletes. The success of the teams and individuals at Center Grove High School are directly related to the hard work and dedication of Coach Mills. In my opinion, Marty has set a very high bar for strength coaches in the state of Indiana to achieve. His passion and work ethic inspires me to work hard every day in this field.

School of Strength Success

Nick Stoner / Center Grove High School/Indiana University

Being in the school of strength throughout my four years of high school has dramtically changed my attitude, my future, and utimately, my life. I came into this program as a 110 pound boy and came out as a 175 pound man, gaining more and more speed as the years went on lifting with Coach Mills. Dropping times from a 12.4 to a 10.4 should be enough reason for everybody to want to join this amazing program. I could not reccomend this class/lifting progam enough to anybody, there would not be enough time in the day. I was a runner up in the 100 meter dash, and 6th in the 200 meter dash at the Indiana Track state finals my junior year. This senior year I helped the 4x400 meter relay beat the indoor record and also I won the indoor 55 meter dash at the HSR state relays, and now I am just waiting for the outdoor senior results this June. Also, earning All-State as a senior in football, and receiving the Mr. Football for Defensive Backs award. All thanks to this amazing lifting program!!

Is resistance training safe and effective???

One of the unfortunate myths regarding the training of young athletes is the notion that resistance training is either unsafe or unhealthy for younger adolescent and pre-adolescent athletes.  Studies show that young athletes who participate in a regular, well-supervised strength training program generally experience fewer and less severe injuries on the field than athletes who train improperly or not at all.
