A great way to save money on the front end when buying reppins and be able to have the option to expand as you gain strength. Incredibly easy to install.

Originally bought the 85lb, as I wasn't sure I would love the Reppins after trading in my fixed set for these. After realizing I did in fact love the Reppins, I bout the 20lb add ons to get to the 105. Happy I added them, not much more to say other than the Reppins are great and I highly recommend them.

I initially bought the 85lb Rep x Pepin set. I rarely get above 85lbs on dumbbells, but the extra 20lbs cover me all the way…at least for now. It seems sick to get the 125lb dumbbells, but honestly the 105lb set is plenty. It’s definitely the way to go if you want to get your dumbbells up. The coating, color, and fit all work well together. Initially there is a slight color variation just for being right out of the box but it blends once out and about for a couple months. Love these dumbbells. The biggest frustration with upgrading your weight on these is having to dial in the cradle spacing again, but once it’s set you’re good to go and it never catches.
