My review of the Rep x Pepin Adjustable Dumbbells from Rep Fitness. These adjustable dumbbells range from 10 – 125 pounds each. All products were purchased with my own money. These are a great option for any home gym owner, but there are a few things you will want to know before buying. I highly recommend pairing these with the Rep Adjustable Dumbbell Stand to make loading and unloading a breeze.
