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 left and right side by side on unilateral machines.
Make adjustments faster.
Real-time data unlocks progress.
Every workout can be a test.
Get testing data from every workout. Make program changes in real-time to optimize workout time and continue to progress.
Maximize performance with real-time, visual feedback.
Research indicates 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 lat pulldown
Use a variety of training and rehabilitation methods to improve strength, speed, and power — all with one machine.
The Keiser Advantage
Keiser PRT
Conventional Iron
Strength
Power
Speed
Do more, more effectively.
The A400 Lat Pulldown, 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.

“Others build their machines like tanks. We build ours like aircraft — strong, but very light.”
DENNIS KEISER
Pure Resistance Technology™
Low-inertia design makes it more versatile.
Pure Resistance Technology (PRT) drives the design of the A400 Lat Pulldown. We remove as much mass as possible to give you a pure, highly versatile resistance.

DENNIS KEISER
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.
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 variable Resistance (DVR)
Resistance that matches your strength curve.
On a lat pulldown, you’re stronger at some points than at others. We optimize resistance throughout your range of motion. This makes your muscles work at their maximum potential across that range.
A descending curve is designed for pulling motions such as a lat pulldown. Resistance decreases as you push further.
Ideal Resistance
Muscles work at their maximum potential
We’ve programmed the ideal resistance curve for a lat pulldown into the A400 Lat Pulldown.
More resistance where you’re strongest: On a lat pulldown, you’re strongest at the beginning of the concentric phase. Keiser’s DVR optimizes your starting resistance with higher resistance.
Less resistance where you’re weakest: As you continue through the concentric phase, you become mechanically weaker. Keiser DVR decreases resistance to match your body’s natural strength curve.
VERSATILITY OF DVR
A Resistance 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 U.S.A. with domestic and globally sourced material.
Unilateral Movement
Train, Rehab, and Assess Left and Right Sides Independently
On the A400 Lat Pulldown, the left and right sides move independently and provide separate data for each side.
A400 Technology
Identify unilateral imbalances.
Get data for each limb to identify problems that can lead to underperformance or injury. Data includes range of motion, velocity, and power.
Prevent unilateral compensation. Prevent the stronger limb from compensating for the weaker limb.
Repair unilateral imbalances. Train and rehab left and right sides independently. Improve symmetry of strength, power, velocity, endurance, and size over time.

Prevent collateral 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 Lat Pulldown 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 - 296 lbs / 0 - 134 kg, it’s easy to find the right resistance level.
Optimize 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.
Foot Pedal Resistance Control
Change resistance on the fly during exercise.
Change resistance at any point during a rep with foot-controlled 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 2133

STRONGER BACKS START HERE
The A400 Lat Pulldown redefines upper-body training with a unique movement pattern and unilateral functionality, ensuring balanced strength development and improved muscle activation. Unlike traditional lat pulldown machines, its innovative design allows for independent arm movement, preventing the stronger side from compensating for the weaker side. Keiser’s low-inertia, pneumatic resistance delivers smooth, controlled movement, reducing joint stress while maximizing power output. Perfect for athletes and users of all fitness levels, the A400 Lat Pulldown enhances back strength, stability, and overall performance. Integrated with Keiser’s advanced A400 technology, it tracks real-time performance metrics and seamlessly syncs with the Keiser Metrics App for precise, data-driven training optimization.
