I sort of regret purchasing these, but the problems stem from my own stupidity and lack of research. I had assumed that I could adjust these weights in a way that turns out not to be possible. I thought I could use these weights at ten pounds (per barbell) then go up to 15, then 20. I've been using 5 lb weights & 10 lbs is the next logical step up for me. With these weights, however, one must jump from 5 lb to 15 -- I found that to be too difficult for myself. Also, the weights are large and bulky and makes some weight training moves a bit awkward and difficult. Perhaps that is just a matter of getting used to them. In any case, these ARE a good deal if they meet your purposes. Just be advised that the weight plates one receives with this set are as follows: Four 2.5lb plates and four 7.5lb plates. Divide those between too barbells and there you will clearly see your options. I still plan on using these, albeit, I'll probably buy a set of 10lb weights until I can work up to 15lbs on most exercises.
