This set is great because you can use it in different ways — dumbbells, barbell, and even for push-ups. The weights are easy to change and it’s convenient for home workouts. Good quality and a solid value for the price.

Great set. I had to carry the box in by myself and was too tired to use it once I got everything unpacked but it's heavy duty and easy to assemble. Definitely worth the money. The dumbbell handles are a little longer than standard but I'm sure it's because they screw to a third piece to make it a barbell, it's a little awkward at first but not a deal breaker.

Great starter set if you’re new to lifting and want something versatile for home workouts. The ability to switch between dumbbells, barbell, and kettlebell is a huge plus, and it’s been solid for the few weeks I’ve used it. That said, it’s not perfect. The kettlebell handle is thicker than standard and can feel awkward. Some exercises are a bit clunky because the weights get in the way, so you’ll find yourself adjusting your grip. The barbell is also pretty short, which makes hand placement feel cramped. For reference I am 5'3. Overall, if you’re a beginner and want convenience over perfection, this gets the job done. Just don’t expect gym-quality ergonomics.

I really like these dumbbells for how much they cost they came with a good variety of weights and are adjustable. I am able to do different work outs with them with all the different attachments they have and they are easy to add on weight or take it off I would recommended.

I was pleasantly surprised it came with the stuff it did for the price. Definitely great for a beginner, as I am a total newbie, so I'm grateful this was so user friendly. I can see the handles being a little too short for some hands, I have large size hands and my hand almost completely covers the dumb bell handles, but it's comfortable. They also send a pair of blue fingerless gloves to grab the handles which was nice of the company to do, and a pair of wrist bands..? I'm not entirely sure what I need them for but, again, I'm new to this and might need them for something later on. I got the 45lb weight kit and they feel great and durable. The barbell feels comfortable with foam covering it, which is a huge plus for me because I had purchased a barbell cover and didn't need it at all. I do enjoy how easy it is to break apart and store, nothing is longer than 2 to 2.5 feet and the plates are pretty compact as well. Wish me luck on working out!

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.

Nice set if you're starting out. Gets the job done. I'm able to do many workouts.

These have been great for adding to my Ladder app Pilates workouts. I wish you could buy more of the parts like the plastic nuts to replace or make it so the kettlebell can be set up while the dumbbells are too. It would also be great to be able to purchase additional weights separately so you could increase your weight without buying a whole new set. They are obviously bigger than the normal dumbbells or plates but it hasn’t hindered me too much. The padded barbell is a great addition.
