Please Note, You will need to buy an air compressor and an upgraded screen along with the machine. Each air compressor works for up to 8 machines, while the new A400 screen can power up to 16 machines. The new screen requires the compressor to power the screen, giving the user the best experience to the user.  

MODEL 1550

A400 Belt Squat

BETTER DATA, MOVE VERSATILE. MORE EFFECTIVE. SAFTER. A BETTER BELT SQUAT FOR EVERY BODY.

The finest in American engineering and manufacturing.

Made in the U.S.A. with domestic and globally sourced materials.

 


A400 TECHNOLOGY 

UNLOCK TRAINING AND REHAB POTENTIAL WITH PRECISE, REP-BY-REP DATA.

The A400 technology offers visual feedback and performance insights in real time.
And you can export A400 data for use in your analytics or records platform, whether it’s custom or off-the-shelf.


Power

See mean and peak power for each rep.


Velocity

See mean and peak velocity for each rep.


Range of Motion

See data for both concentric and eccentric phases for each rep.


Unilateral Comparison

See velocity and power data for the left and right side-by-side on unilateral machines.


Every workout can be a test.

Get testing data from every workout. Make program changes in real-time to optimise workout time and continue to progress.


Maximise performance with real-time, visual feedback.

Research indicates that real-time visual feedback can increase athlete intent. A400 technology provides the feedback that inspires improved performance.


Quantify progress automatically.

Capture vast amounts of performance data in the weight room or clinic. A400 makes it easy to capture force, velocity, power, and range of motion to track progress.


Performance drop-offs show when to stop.

Set custom performance drop-off levels (e.g. 80% of peak power). See when more reps would produce diminished returns. Know when to end a set to save time and reduce risk.




VERSATILITY

A MORE VERSATILE BELT SQUAT

Use a variety of training and rehabilitation methods to improve strength, speed, and power — all with one machine.


DO MORE, MORE EFFECTIVELY.

The A400 Belt Squat, with Pure Resistance Technology™ (PRT), gives you more training and rehab options. That’s because it’s more effective than iron at a wide variety of speeds.


✅ More effective at faster tempos to improve velocity and power. 

✅Just as effective at slower tempos to improve strength. 



Pure Resistance Technology™

LOW-INERTIA DESIGN MAKES IT MORE VERSATILE.

Pure Resistance Technology (PRT) drives the design of the A400 Belt Squat. We remove as much mass as possible to give you a pure, highly versatile resistance.


“Others build their machines like tanks. We build ours like aircraft — strong, but very light.”

DENNIS KEISER - CEO, Keiser Corporation

LOW-INERTIA ARCHITECTURE

WE REMOVE ANY MASS WE DON’T NEED.

We engineer the linkages between you and the resistance to have as little mass as possible. With less mass, there’s less inertia and momentum.

PNEUMATIC RESISTANCE

A MORE VERSATILE ALTERNATIVE TO IRON

We use compressed air under digital control instead of iron resistance. It has almost no mass, inertia, or momentum. No matter how fast you move, you can’t throw it, and you don’t have to slow it down.

VERSATILITY

LOW-INERTIA MEANS MORE WAYS TO TRAIN AND REHAB, MORE EFFECTIVELY.

With almost no inertia, your resistance is more effective and safer at a wide variety of speeds. This gives you more ways to train and rehab.

DYNAMIC VARIALLE RESISTANCE (DVR)

RESISTANCE THAT MATCHES YOUR STRENGTH CURVE.

*An ascending curve is designed for pushing motions such as a belt squat. Resistance increases as you push further.

On a belt squat, you’re stronger at some points than at others. We optimise resistance throughout your range of motion. This makes your muscles work at their maximum potential across that range.


IDEAL RESISTANCE

MUSCLES WORK AT THEIR 
MAXIMUM POTENTIAL

We’ve programmed the ideal resistance curve for a belt squat into the A400 Belt Squat.


1. Less resistance where you're weakest: On a belt squat, you’re weakest at the beginning of the concentric phase. Keiser’s DVR optimises your starting resistance with lower resistance. 


2. More resistance where you’re strongest: As you continue through the concentric phase, you become mechanically stronger. Keiser DVR increases resistance to match your body’s natural strength curve.

VERSATILITY OF DVR

A RESTITANCE CURVE THAT KEEPS ITS SHAPE AT ANY SPEED

Inertia and momentum distort iron’s resistance curve. The faster you go, the more it changes. Thanks to Pure Resistance Technology, Keiser’s DVR will match your body’s ability to produce force, no matter your speed or resistance setting.

The finest in American engineering and manufacturing.

Made in the U.S.A. with domestic and globally sourced materials


PERVENTS COLATERAL DAMAGE WITH ALMOST ZERO SHOCK LOADING.

Iron's inertia and momentum may cause repeated stress on joints and connective tissue. Keiser eliminates that, so your training is far less likely to cause injury.

✅ Avoid repeated shock loading: The A400 Belt Squat has virtually none of the sudden excess forces you get from iron.
✅ Protect your joints: With almost no shock loading, you avoid much of the risk to joints and connective tissue over time.
✅ Less pain when you work out: Without the shock loading of iron, you get all of the benefits of strength training with significantly less pain.


OPTIMIZE RESISTANCE

CHOOSE THE PRECISE RESISTANCE FOR YOUR GOALS.

With one-pound or one-kilogram increments, ranging from 0 - 785 lbs / 0 - 356 kg, it’s easy to find the right resistance level.


✅ Optimise your resistance level. Set resistance at the precise level best for you and your goals.
✅ Don’t wait for the next ten pounds. Continually challenge muscles with frequent, small increases in resistance.
✅ Ideal when training for speed and power. Small increments are an important tool when training fast with lower resistance.
✅ Perfect for rehab and reconditioning. One-pound increments and a low starting resistance help find the right resistance level to recover from injury or a deconditioned state.

THUMB-BUTTON RESISTANCE CONTROL

CHANGE RESISTANCE ON THE FLY DURING EXERCISE.

Change resistance at any point during a rep with push-button convenience and digital precision.

✅ Isometric overload made easy. Get into an isometric position, then increase resistance for isometric training.

✅ Eccentric overload made easy. Increase resistance after the concentric phase of a rep.

✅ Get rehab patients into position before adding load. This makes it easier to determine what resistance level the patient can achieve in tiny increments.

 




Model 1550

A400 BELT SQUAT

ENGINEERED TO PERFORM. BUILT TO LAST.

LNNOVATE ENGINEERING. SOILDLY RELIABLE. AND SIMPLY MORE VERSATILE.

BELT UP / LOAD UP

Build explosive hip and leg strength with up to 800 pounds of smooth, pneumatic resistance, all while minimising stress on your shoulders and spine. The A400 Belt Squat is ideal for those who want to avoid or cannot load their spine, as it eliminates spinal column pressure and accommodates users from 4’8” to 7’ tall with pivoting handles. The wide base and optional deadlift bar offer a range of versatile training options. With Keiser’s A400 line technology, it tracks real-time performance metrics and seamlessly integrates with the Keiser Metrics App for data-driven training optimisation.
