Are you eager to experience it firsthand? Reach out to us at info@fightstarco.com or give us a call at 0333 090 8786 to schedule your personal viewing. This is your opportunity to explore the entire Keiser range that we offer, all available for in-person experiences. Don’t miss out on the chance to see and feel what makes Keiser products exceptional!  (T&C Apply) 

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.  

EVALUATION ON EVERY REP

The A400 Leg Press is designed to optimise lower body strength training with smooth, pneumatic resistance. The higher foot plate increases hip flexion
while decreasing knee flexion, which maximises glute activation at the start
of the movement. Reducing knee flexion helps minimise shearing forces, preserving the health of your knees. The separate foot plates allow you to train each leg independently, mimicking natural movement patterns and promoting balanced strength.
Perfect for users of all fitness levels, the A400 Leg Press provides a safe,
effective workout while tracking real-time performance metrics with Keiser's
advanced technology. 

KEISER DYNAMIC VARIABLE RESISTANCE

Keiser’s Dynamic Variable Resistance is designed to provide a smooth, consistent Variable Resistance force curve at any training speed. Each machine has its own unique Variable.
The resistance curve is designed and tuned perfectly for the muscles being used in that particular exercise. For users, this means that working out at any speed, you’ll always be training at maximum efficiency.

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 variable Resistance (DVR)

Resistance that matches 
your strength curve.

On a leg press, 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 leg press into the A400 Leg Press.

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

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 RESISTANCE CURVA THAT KEEPS ITS SHARP 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.

 

UNILATERAL MOVEMENT

TRAIN, REHAB, AND ASSESS LEFT AND RIGHT SIDES INDEPENDENTLY

On the A400 Leg Press, 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 the left and right sides independently. Improve symmetry of strength, power, velocity, endurance, and size over time.

 

PREVENT COLLATURAL 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 Leg Press 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.

OPTIMISE  RESISTANCE 

CHOOSE THE PRECISE RESISTANCE FOR YOUR GOALS.

With one-pound or one-kilogram increments, ranging from 0 - 924 lbs / 0 - 419 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.
