Weight Stacks

At BAC we feature Cybex Selectorized Weight Stack Circuits comprised of VR-1 and VR-3 models.

Cybex VR-1 models have numbered weight stacks and either come with the same size plates in the entire stack or have a graduated weight stack that has smaller plates then transition into larger ones. The numbers on the plates provide an index as to how many plates there are. The plate number does not reflect the amount of weight each plate represents they are for index purposes. Each machine also has an add-on plate that hangs right next to the weight stack to make smaller weight increases.

Cybex VR-3 models have the approximate weight imprinted on plates and progress in 20lb increments. To one side of each stack are 3-round 5lb add on weights to allow 5lb increases prior to moving to the next plate.

Cybex Selectorized Weight Stack Equipment are variable resistance machines, which means as the resistance is lifted the weight changes through the range of motion giving more resistance when you have a mechanical advantage and less resistance when you do not. To allow the machine to efficiently deliver the appropriate resistance through the range of motion the user needs to move the resistance at a slow controlled speed. A typical recommendation is a 2-4 second lift, 1-2 second pause, and a 4-6 second lowering then repeat.

If you have any questions regarding the usage of our Cybex Equipment please see one of our BAC Personal Training Staff. They would be happy to help!
