Vertical Knee Raise Attachment VKR30

Hello John Thank you for your question. The Vertical Knee Raise Attachment VKR30 is just an attachment for the home gym system. For the VKR chair to work you would have to purchase the body solid EXM3000LPS Home Gym. If you were looking for a VKR specifically we have a few options, here is the link http://www.treadmillfactory.ca/core-abs-backIf you have any further questions feel free to contact me at tinikawalters@hotmail.comRegardsTinika

Hi John,There is a chest press option on the EXM3000LPS gym. The unit comes with 2 x 210lbs weight stacks that is shared between the 2 stations. The VKR30 attachment you are looking at does not work in any way with the weight stacks. It is a seperate add on just for knee raises and dips.If you have any other questions, email me back at edwin@treadmillfactory.caThank you
