Speedflex machines create resistance for your workout through the sophisticated technology of hydraulics and electrical impulses.
A Speedflex machine employs only concentrically based forces, i.e. forces which are placed on the machine by the individual, therefore eliminating all gravity based (eccentric forces). By eliminating eccentric forces, which traditionally need to be performed at a slow speed with great control, there is a significantly reduced chance of injury.
The machine allows users to accelerate through the exercise with their greatest amount of force at a high speed. This efficiency in training provides maximum results without causing damage to muscles, the primary cause of post exercise pain.
The Speedflex machine has a free motion bar which, unlike traditional resistance exercise machines, requires users to apply force through the entirety of the exercise, as opposed to increased force in one direction, followed by a controlled movement back to the starting position. This means that even the most basic of exercises will become bigger and more complex, requiring the use of opposite muscle groups.
As there are no weights and the resistance is set at all times in both directions, the momentum users would usually experience during resistance training (when an object continues to move in the desired direction after the application of force), is eliminated, meaning the user must work to their optimum level to complete the exercise.
Speedflex machines also operate on a closed loop circuit which means resistance is automatically adjusted in response to user-generated forces. When the body begins to fatigue, the machine will adjust the resistance to maintain an individualised optimum workout.
