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.

Kettlebells are not my only exercise tools, we do utilize many other methods of training in our system. Having said that I am a HUGE believer in their effectiveness and efficiency in helping people of all ages and fitness levels reach their goals.

At the School Of Strength you will see numerous full-body exercises that improve strength, endurance, speed, coordination and flexibility. With kettlebells, power lifting, olympic lifting, medicine balls, power bands, sandbags, power racks, bench presses, pull-up bars, fat bars, elite rings for suspension training, thick battling ropes, thick ropes to pull, speed & conditioning sleds, tires, foam rollers, speed and agility ladders, hurdles, cones, jump ropes, plyoboxes, and over 1,000 square feet of turf, you’ll always find something new and challenging to push your strength, speed, and conditioning to the next level.

We have a simple but effective training program to give you everything you need for improved fitness and sports performance.

It's simple, but it's not easy.

No gimmicks, just sound tried and true methods that delivers RESULTS!

What makes our program so different? The main principle is that we train 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. Most lifts will be done on the feet and all lifts will strengthen the core. It is critical to your success that you master these movements through persistant and patient practice.
