パック 5 I have a small space in my "man" room in which I have freed up as my workout area - 2m x 1.2m. I've bought some dumb-bells, and barbells with a plate weights up to 120K in total - so nothing to boast about - all being 28mm in hole dimension due to the limited space I've set aside, and the bars up to 120cm in length.My experience to-date, has been that you need to buy "Spring clips" for the screw-thread bars, and clamps for those without the threads. However with these cheaper models of bars you also need to buy a vacuum cleaner, since they all... leave small shards of chrome metal upon the flooring after use - which is rather uncomfortable for your bare feet. If you want pictures of this, I can provide, but I think others have already done so. I use a small "Dyson" hand-held vacuum cleaner - normally used for futon "dani"... but it does the job.
