I have looked at all of the free weights and have emailed our facilities director to advise on what needs doing to rectify this. (this will probably involve bolting everything down) When I get a date for this I will let you know.
I agree that the unassisted chin needs to be moved and plan to do this at the weekend when I have enough staff in to help!
Lastly with regards to the wear covers, these are all going to be removed as we are changing the way that we brand the machines. For now though they must stay as they are. I will keep an eye on the chest press cover however I think that it may be down to the fact that it is new, this may stiffen up after a bit more use. I have had a few members and staff test it today and so far there doesn’t seem to be a problem with it slipping.
