Exercise Concept and History

Strength Cardio Aerobic Stations Circuit gym class Safe Strength Training and Cardio Exercise in each machine! Advanced Performance Equipment

The Hydraulic Circuit Training System 

The aerobic/anaerobic strength training circuit is an advanced program offering unparalleled results. 

Hydraulic exercise originated in 1967 as an advanced sports training program for athletes because of its ability to safely produce more aerobic power in a shorter period of time. Now, everyone from youth to the elderly are enjoying the benefits of this amazing equipment.


In 1967 a high school football coach witnessed too many young football players getting injured while training on heavy weights. As a result, he devised a safer way to increase strength using the fluid resistance of a hydraulic cylinder mounted on various strength machines in place of the iron weights.

Soon after implementing his new training program his players began to advance far beyond what he had expected. He quickly discovered there were many more benefits to using hydraulic cylinders for resistance training than he first thought. 

He discovered that over-building muscles with iron weights slowed speed and decreased flexibility compared to hydraulic resistance training. Slower speeds and decreased flexibility increases the risk of injury whereas hydraulic resistance training increases speed and flexibility thereby decreasing the risk of injury.

Much to his delight, hydraulic resistance training produced increases in 

1) Strength   2) Aerobic Power   3) Speed   4) Muscle and Cardiovascular Endurance  5) and even Flexibility!  

From 1970 Hydraulic Exercise Training has become more and more popular with: 

Professional Athletes

Physical Therapists

Medical Rehabilitation Therapists

Olympic Teams and Coaches

and hundreds of college and high school football teams.  

Here are the primary reasons:

  • Fluid resistance is safe and gentle on joints and muscles.
  • Reduction in injuries means you can stay in the game!
  • Greater gains in all 3-power sources:
    • Aerobic exercise produces cardiovascular endurance
    • Interval training produces cardiovascular power
    • Resistance training produces strength


In the late 80's, Henley Healthcare Company, introduced an exciting program the the Health Club Industry called P.A.C.E. It was an instructor led group fitness class done in an interval format that was set to music using hydraulic exercise machines.

P.A.C.E. became popular in many health clubs in the U.S. especially with women. The reason was not only because women love the social interaction of group exercise but they quickly discovered the amazing fat burning benefits! 

In a very short period of time a person working out on the hydraulic circuit can lose an amazing amount of body fat. It is for this reason that the 30-minute hydraulic interval training circuit workout exploded in popularity around the world.

Women's health club chains began popping up like mushrooms around the world!

Since then, the hydraulic circuit training program has produced fitness franchises and independent health clubs in over 100 countries around the world.

Now, everyone is benefiting from these incredible machines! 


AeroStrength hydraulic strength training provides 100% maximal muscle overload.

AeroStrength combines the principles of isotonics and isokinetics. As both the speed and the resistance vary, through out the range of motion, AeroStrength provides maximal (100%) overload at all joint and angles which provide optimal increases in muscular strength, power, speed, and endurance. 

Now athletes can train how they perform, with speed!

Strength training on hydraulic machines can safely be done at a fast pace thereby becoming a powerful cardiovascular training system and cutting the training time in half!

As the muscle fatigues, the mechanics of the hydraulic cylinder automatically adjusts so the user is still working at 100% of what the muscles are capable of generating. The cylinder automatically matches the speed and force of the user. 

This is huge in terms of endurance for optimal athletic performance.

And unlike weight machines, muscles worked on hydraulic machines experience smooth fluid resistance thereby decreasing downtime due to muscle soreness or injury.


AeroStrength is made in American and offers unique design features that produce phenomenal results at an affordable price for nearly all projects. 

Our Philosophy is simple: 

Offer the highest quality product at the best price with the longest warranty and excellent customer service.

We manufacture commercial gym equipment that is safe strength training equipment for home fitness, physical therapy, clinical rehab, geriatric exercise, and athletic and sports performance training.

The muscle mass is gained by the resistance provided by the hydraulic pistons (cylinders) filled with fluid, typically hydraulic oil. Hydraulic Fitness Equipment is used in physical therapy and rehab to build muscle throughout the full range of motion. It is the only strength equipment that can safely be done with speed and is the main reason professional athletes use hydraulic resistance also called velocity enhanced resistance. Hydra is short for hydraulic and Hydro is also used to describe fluid exercise and fluid-filled resistance machines.

While we oftentimes sell other brands of used hydraulic fitness equipment we do not sell or manufacture the Curves for Women machines or circuit sets. Our machines are similar to Curves in that we both use hydraulic cylinders but our cylinders are heavy duty commercial hydraulic pistons that are hand-made in America, by us, for human exercise only. The hydraulic cylinders used on the Curves machines and many other brands are usually mass produced automobile shock absorbers.

If you are searching for commercial gym equipment sets, physical therapy equipment, exercise equipment for chiropractic rehab, athletic performance training equipment, or for a unique way to enhance your gym equipment offering, we have the quality workmanship and best prices for your project.

We provide training and manuals along with group circuit workout essentials. We can also assist you with business planning, licensing, franchising, private labeling, branding, and all phases of start-up assistance and consulting. Check out our Store for items that you may find helpful during your start up phase. We encourage questions and ideas on how we can produce better products and services, so give us a call at 1-918-949-8362 or email
