The Keiser Difference

There are those who are satisfied with the status quo, the conventional view, the path of least resistance. They choose to follow rather than take the lead. Their future is predictable and comfortable.

I’m not one of those people. And Keiser is not, and never will be, one of those companies.

Our only interest in the status quo is to challenge it. 

Our goals from the beginning have been to:

1. Raise the bar on human performance at all levels
2. Maximize the efficiency of physical training
3. Minimize injuries in the gym, in the game, and in life

To do this, we knew we had to be able to move a resistance at very high speeds, and be able to vary that resistance through the entire range of motion to maximize results and minimize injury. We call this Dynamic Variable Resistance.

Variable Resistance is the key to safer and more efficient strength training. It’s based on the fact that, in every exercise, your ability to produce a force varies through the range of motion. At certain points, you’re stronger and at others you’re weaker. Ideally, you want your muscles to work at their maximum potential through every point in the range of motion. To do this, we must apply more resistance where you are stronger and less resistance where you are weaker.

While iron could be used to do this, it was highly impractical at the speeds necessary to achieve the level of performance we were shooting for. It’s the speed that makes it Dynamic Variable Resistance.
