    keiser rackWhat Is The Keiser Rack?

    The Keiser Rack is a Squat Rack that utilizes both mass and pneumatic resistance. The design consists of a sturdy vertical framework with adjustable hooks or J-cups that can hold a barbell at various heights.

    It has the option to add additional features, such as pull-up bars, dip bars, safety bars, and plate storage. Some models of the Keiser rack are designed to be compact and space-saving, while others are larger and more heavy-duty.

    Keiser is a well-known brand in the fitness industry, and their equipment is often used in commercial gyms and elite professional training facilities. The Keiser rack is a popular choice for strength training enthusiasts and athletes who want a high-quality, versatile piece of equipment for their home gym or professional training space.

    How Does The Keiser Rack Work?

    The Keiser Rack is connected to the Keiser Air Compressor, which allows users to increase or decrease air resistance on the fly.

    The air resistance is applied via cables that come up from the base of the rack, connecting to an adapter that attaches to the end of the barbell. The cable is attached to pulleys, which allow you to maintain air resistance while moving forward, backward, or staying in the same place.

    To adjust the resistance, simply place your foot on the air adjustment levers at the base of the squat rack to increase or decrease the load by one pound at a time. Additionally, plates can be added or removed from the bar to increase or decrease the mass-based loading used in the exercise.

    What Data Does The Keiser Rack Show?

    The Keiser Rack comes with a display that will give you useful data and instant feedback with every repetition.

    With the Keiser Rack, you are able to see Peak Power output in watts, the number of repetitions performed, the percentage of peak power per repetition, as well as the load.

    The instant feedback via power output ensures that athletes can see how they are performing each rep, and this can be used as a teaching tool or a motivational tool so that athletes push themselves every repetition.

    Having used Keiser equipment, I can say that having this instant feedback has helped me push myself, as well as make it easier to track my performance. Over time I have seen my power output increase in various exercises, and this was easily tracked thanks to the data provided by the Keiser Rack. 



    How I Use The Keiser Rack In Training Athletes.

    The Keiser Rack is a staple of my strength and conditioning training for athletes, as it allows me to target the qualities that I want in a precise manner.

    Air & Mass Ratios Using The Keiser Rack

    Because it allows you to utilize both mass and air-based resistance, you can dial in the loading to fit the goals of the workout.

    For example, you can utilize different ratios of mass and air resistance, such as:

    25% Air, 75% Mass

    I use ratios such as this when I am looking to develop maximal strength. The smaller amount of air resistance helps to keep loading consistent through the range of motion and minimize issues related to momentum, while still ensuring the athletes are more loaded at the bottom and have to work hard to reverse the load. This works best for deep squats, high box step-ups, RDLs, and split squat variations.

    50% Air, 50% Mass 

    Once I am transitioning from maximal strength into a more power or rate of force development-oriented phase of training, I will bump the ratio up to be closer to 50/50 air & mass. This allows for snappier, higher RFD movements with very rapid reversals, while still giving athletes a feel similar to traditional loading. This loading scheme works best for low box step-ups, heavy quarter squats, and early in the transition toward drop squats.

    75% Air, 25% Mass

    When it comes time to peak an athlete, such as before sprinting in a track & field competition, I bring the ratio up to predominantly using air resistance. This allows for an extremely rapid early phase rate of force development numbers, very short times to peak velocity, and allows me to emphasize force production in the first 100 to 200 milliseconds of the movement. This loading scheme feels most similar to sprinting and is great for step-ups, drop squats, and other explosive movements.

    100% Air, 0% Mass

    Sometimes I will use purely pneumatic resistance, whether that be to maximize movement speed, reduce wear and tear on the joints, or for doing high-velocity strength endurance. For example, I will use 100% air on hip thrust variations, bench press, overhead press, and pogo hops throughout the training year.

    As you can see, the ability to manipulate air resistance and mass ratios gives you many more options with how you load your athletes. Looking for rapid reversals and high RFD? Go for more air. Looking for raw strength? Emphasize more mass.

    Whatever your goals, the versatility of the Keiser Rack puts the power in your hands to precisely load athletes based on their needs.

    What Is Keiser's Pneumatic Resistance?

    Keiser's pneumatic resistance system is a type of resistance training that uses compressed air to create resistance. This system is used in all of Keiser's strength training machines, including their weight machines, functional trainers, and cardio equipment.

    Most Keiser equipment uses pneumatic resistance only, whereas the Keiser Rack allows you to combine both pneumatic and mass-based resistance at the same time.

    The pneumatic resistance system works by using compressed air to create resistance as the user performs an exercise. As the user applies force to the machine, the air pressure inside the machine increases, creating greater resistance. This resistance can be adjusted by changing the air pressure within the machine, allowing for precise and customized resistance levels for each user.

    What Makes Pneumatic Resistance Different?

    The main difference between Keiser's pneumatic resistance and mass-based resistance (such as traditional weight plates or dumbbells) is the physics involved.

    Mass-based resistance relies on the force of gravity to create resistance, while pneumatic resistance uses the pressure of compressed air.

    In mass-based resistance, the resistance is created by the weight of the object being pulled down by the acceleration of gravity. This is why when lifting normal weights, the weight is much heavier at the bottom than it is at the top.

    As you drop in a squat, the mass is accelerated downward and gains momentum, which makes it hard to stop and reverse quickly at the bottom. Once reaccelerated upward, the weight will begin to feel lighter and sometimes even fly off of your back at the top of a squat.

    In contrast, Keiser's pneumatic resistance is not reliant on gravity, and its isotonic nature means that no matter how fast you move, the load will be the same. This allows for athletes to attack movements in the gym much more aggressively, and through a full range of motion, because of the fact that the load is not crushing them at the bottom and getting very light at the top.

    Pneumatic resistance is also very convenient, in that it can be adjusted one pound at a time, instantaneously, allowing for more precise resistance adjustments and a greater range of resistance levels.

    Overall, Keiser's pneumatic resistance system offers a unique and versatile approach to strength training, with several advantages over traditional mass-based resistance training.

    It allows for precise and customizable resistance levels and is often preferred by athletes and trainers who want a more dynamic and functional form of resistance training. Pneumatic resistance is optimal for use during aggressive, explosive types of movements that athletes need to perform in order to get better.

    What Are The Benefits Of Keiser's Air Resistance?

    Keiser's air resistance system offers several benefits when compared to mass-based loading systems. Here are some of the key advantages of Keiser's air resistance system:

    Air resistance provides Increased safety.

    Air resistance systems like Keiser's are generally safer than mass-based loading systems, particularly when it comes to reducing the risk of injury from dropping weights. This is because the resistance is generated by air pressure, rather than a solid mass that can cause injury if dropped.

    Pneumatic resistance is not affected by momentum or inertia.

    Inertia and momentum can be an issue with mass-based loading, particularly during exercises that involve explosive movements or changes in direction. Keiser's air resistance system allows for smoother resistance throughout the range of motion, minimizing the potential for injury due to inertia or momentum.

    Air resistance can be adjusted more precisely.

    With mass-based loading, the resistance can only be adjusted by adding or removing weight plates. In contrast, Keiser's air resistance system allows for precise adjustments to the resistance level, making it easier to target specific muscles and adjust the intensity of a workout. The resistance can be adjusted quickly and easily, without having to stop and adjust the weight plates on the bar.

    Pneumatic resistance offers more versatility than mass-based resistance.

    Keiser's air resistance system allows for a wide range of exercises, from strength training to cardio, all in one machine. This makes it easier to target multiple muscle groups and incorporate a variety of exercises into a single workout.

    Air resistance has a lower impact on joints and tissues.

    Air resistance can be easier on joints than mass-based loading, particularly for individuals with joint issues or injuries. The resistance is smoother and more controlled, minimizing the impact on joints during exercises while maximizing muscle activation.

      Overall, Keiser's air resistance system offers a number of benefits when compared to mass-based loading, making it a popular choice for athletes, trainers, and fitness enthusiasts alike.
