This is what I do - also good for musle building
This is also what I do too. I can just about manage lifting it off on my own with the 4 x 591 racks then it gets chained to a steel fence at the back of my driveway.
It started out on my Astra estate with the roof rails but with a feet swap (sold old and bought replacement from
ebay for very little swap cost) it now fits my Passat B5.5 saloon. Something to be aware of with the thule system is that there is different roof bar widths and depending on vehicle you may find it necessary to swap bars as well as the foot pack fittings.
