Keiser

For nearly four decades, Keiser has influenced the training of athletes, fitness enthusiasts and rehabilitation experts worldwide with better fitness products that unite both components of human performance: the force you produce, and the speed at which you produce it.

For over 40 years, Keiser has been changing the way people of diverse ages and abilities exercise, while helping to improve their performance and quality of life. However, this success story began over 45 years ago when Dennis Keiser was hired to design the first variable resistance machines for a leading manufacturer. A year later he launched “Commercial Design”, a consulting engineering company that specialized in exercise equipment design. In 1976 Dennis’ brother Randy joined him and a year later they formed Keiser Corporation. After a number of patents in both weight stack variable resistance design and hydraulic resistance design, Dennis applied for patent protection on a totally new concept for variable resistance using compressed air (pneumatics). In 1978 the brothers introduced to the world the first air powered variable resistance exercise machines for building strength and power.

Our machines are equipped with patented Keiser pneumatic technology to give everyone from first-time gym members to pro athletes a safer, easier, more efficient way to boost power output, improve core stability, and gain overall muscle performance.

AIR250

Keiser Air250 Abdominal Machine

Few machines can duplicate the movement and effectiveness of the innovative AIR250 Abdominal. What sets it apart is its ability to create an intense abdominal workout without involving the hip flexors employed by other abdominal machines on the market. A fully adjustable seat and comfortable chest pads help establish the correct position for the exercise, ensuring that target muscles are activated.

Keiser Air250 Arm Curl Machine

To develop bicep muscles while protecting the wrists and elbows, the Keiser AIR250 Arm Curl is the ideal machine. For a better forearm workout, grips also allow for the hammer curl position. To provide additional comfort during exercise, the AIR250 Arm Curl offers extra padding in the high load areas and a fully adjustable seat.

Keiser Air250 Lat Pulldown

The revolutionary design of the Lat Pulldown eliminates the cable, thereby reducing the maintenance and, better yet, the chance of injury to the user. The Air250 Lat Pulldown is the first to use the mechanical linkage to provide the proper linear pull previously obtainable only with a cable system. The open handlebar design with range of motion adjustments accommodates various body sizes and flexibilities.

Keiser Air250 Leg Extension

AIR350

Keiser Air350 Biaxial Chest Press

The creative engineering of the Air350 Biaxial Chest Press combines two chest movements into one exercise. As you press outward the hands also move inward, taking the chest muscles through a greater range of motion. This increased range of motion, along with the natural strength curve generated by the biaxial movement ensures maximum development of the important muscles of the chest and upper arms. The individual movement of the exercise arm prevents the stronger side from helping out the weaker side. Range of motion adjustments accommodate various body sizes and flexibility.

Keiser Air350 Biaxial Upper Back

The Air350 Biaxial Upper Back incorporates a unique design with unilateral/bilateral movement. Designed for superior isolation of the upper back, this machine features an adjustable chest cushion, which helps stabilize the exercise posture while concentrating on the ‘elbow out’ position, to ensure high upper back engagement through the full range of motion. The unique unilateral option promotes symmetry by assuring that the stronger side does not compensate for the weaker side.

Keiser Air300 Seated Butterfly Machine

Designed with comfort in mind, the handgrip and forearm cushioning make correct body alignment simple. A fully adjustable seat allows users up to five different ranges of motion to work both the upper and lower pectoral muscles for full chest development. The 350 Seated Butterfly is designed to minimize over-stretching that might occur with other ‘pec decks’ by providing a wide variety of adjustable starting arm pad positions. Independent arms allow users to exercise one arm at a time for variation.

KEISER RACKS

Keiser Power Rack

The POWER Rack works by incorporating pneumatic strength columns, which can be attached to the bar, allowing Keiser’s patented air technology to be used solely, or in combination with, free weights. This allows for a wide spectrum of training, enhancing power and stability for the athlete. Athletes who have trained on the POWER Rack have seen overall strength gains, better speed, control and explosive power. The POWER Rack is a favorite unit for professional sports teams. Our POWER Rack without Air is also available in these same specs.

Keiser Rack and a Half

The Rack and a Half uses the same pneumatic strength columns as the POWER Rack, but was designed to accommodate multiple users. By adding additional pulley tracks to the rear of the unit, which can be attached to the bar, this allows two users to exercise simultaneously. Both stations can utilize air, free weight, or the two in combination. Our Rack and a Half without Air is also available in these same specs.

SUPPORT EQUIPMENT

Keiser Support Equipment-FORCE Machine

The Keiser FORCE Machine is a simulated forcible entry-chopping device developed and manufactured by Keiser Corporation specifically for the fire service. It provides an efficient and durable means of training or testing individuals such as firefighters who use axes and sledgehammers in their occupation.  To use the FORCE Machine, an individual straddles the I-beam by standing on the footwalks, and strikes the I-beam using the specifically designed 9-lb. dead-blow sledgehammer. The I-beam is weighted to simulate a railroad tie commonly used in testing many firefighters today. The individual drives the I-beam with overhand swings the length of the track. The movement is biomechanically correct, accurately reflecting structural firefighting tasks. Polyethylene glides on the bottom of the I-beam provide a consistent running surface on the steel track so important in testing. It takes an average of twenty to twenty-five strikes to move the I-beam five feet, a level of effort consistent with many forcible entry situations.

Keiser Stretch Corner

Keiser’s Stretch Corner is capable of accommodating numerous stretches while occupying minimum floor space. With a footprint of only 24 sq ft/2.2 m, it not only fits almost any facility, but also takes up less space than four people would lying on the floor. You can actually regain valuable square footage. Backed by a 10-year structural warranty, the Stretch Corner is built to take years of hard use.

KEISER CARDIO

Our groundbreaking rear-wheel M Series indoor bikes are what made us famous. But the same science-proven Keiser quality is engineered into all cardio products — from the M3i with innovative new pedals to our new M5i Strider elliptical and M3i Total Body Trainer, all equipped with Bluetooth®.
