Great for beginners

Lauren CanadayDecember 23, 2025

These are great for beginners. Only thing negative I’d say is the cap on the ends of the dumbbells do spin while using so the weights become loose and have to be tightened again. Overall good though! Read more

Good quality, great for travel

Liz KDecember 11, 2025

So excited to start using them. I love that it's easy to create combinations of weights depending on your workouts. These are great for traveling during extended periods (at in-law's for two weeks) but also for home. I'm working on increasingly building up my strength and I have 20 to 25 lbs. dumbells for the 5 lb gap is now fulfilled by these that are 22.5 each, plus they can be put together as a barbell. Very exciting! Read more

Decent Starter Set

CustomerDecember 20, 2025

3.5 stars If you are wanting to start working out but not spend money this is a good starter option. It was easy to swap the weights and bars to create the weights. Barbell made for a smaller framed person. We used it until we moved to a plave with a nice gym. It was incredibly convenient. Read more
