This is a hydraulic resistance machine that does not have to be pre-adjusted. This allows the user to train right away while resistance can increase based on when the unit is made. This will be safe to use and will not create more resistance after it is lifted up. The movement is easy to manage and shocks will not occur. This uses six resistance levels and is easy to move without needing much maintenance. This is also great for home training needs. The steel frame is epoxy painted and come in many colours.
