Most customers say that the resistance is similar in feeling to a pneumatic system. This is because the resistance mechanism of the ANCORE is not dependent on gravity and allows for high-speed, ballistic movements as well as slower, more controlled movements.
The resistance is generated via a torque-loaded spring mechanism. The torque curve is quite flat in the middle cable length range, where most movements are done. There is a slight progression from the first foot of cable compared to when the cable is pulled out at 8 feet. There is always tension on the cable at any point, allowing for concentric, eccentric, and isometric movements. Additionally, the resistance is not inertial or flywheel-based.
