great idea but could be better good piece of kit overall but has a few issues with it. firstly you cannot lock the butterfly bars in position for chest press which means each side moves independently which is not ideal and could cause injury. secondly when only the lightest weight top plate is on there is wobble and resistance and the plate does not ride up and down smoothly and sometimes wont go back down onto the weight stack. thirdly there is a lot of resistance on the lower pully even at the lightest weight. more than there should be. Not ideal for cable kickbacks or other ankle strap exercises. Go to product 351 May 2021
