With Keiser Pneumatic Technology, the muscles remain active and engaged throughout the entire range of motion and velocities, with reduced shock loading to muscles, connective tissues and joints, which allows for workout regimens that can safely improve physical performance in ways not seen with traditional strength-training methods.
There are many keys to success, but two invaluable ones are accelerating strength training and accommodating resistance by add-ing chains or bands or sometimes both.
Run the 5/8 chain through the metal loop and adjust it so that half of the 5/8 chain is lying on the floor while the bars in the rack. For example, if your max is 500, put 300 pounds on the bar.
When the bar is on your chest, only the weight of the bar should be on your chest; that is, all the 5/8 chain should be on the floor.
By doing this, you will be locking out an extra 20 pounds.
(They weigh 20 pounds each, but half is on the floor at lockout.) A 500 pound bencher can use both the 5/8 and 1/2 inch chains for a combined added weight of 31 pounds.
A 350 or more bencher should use one pair of 5/ 8-inch-link chain.As a result, Table 1 provides a simple ‘guide’ to the mass-displacement relationships of a variety of chains, and is also downloadable and printable for use in gym facilities.When an exercise is supplemented with either chains or elastic bands, they cause a ‘variation’ in the load being lifted throughout the range of movement – hence the name ‘variable resistance training’. length-load) relationship, simply meaning the higher the chains are lifted, the more weight that is added (Figure 1).The variable resistance provided by the chains may limit their ability to improve force production in untrained athletes, suggesting that a strength/stability pre-requisite may be required to identify their efficacy for a particular athlete.To add to this, because there is uncertainty with how much additional load is applied to the barbell by the chains during an exercise, not only is selecting appropriate chains a difficult task, but monitoring the load becomes even more complicated.
