  • Good and affordable option
Style: E.70LB(35LB Pair)
Great for easy at home workouts when I don’t feel like going to the gym. Affordable option. Wish it came with more of the nuts that hold the weights in place. Be aware the package is VERY heavy when it arrives.

  • Nice set!!
Style: D.45LB(22.5LB Pair)
I like this set very much. The weights work with my TotalGym (great bonus, additional versatility) and it is very comfortable to use as compared to lifting with a metal weight set. It is easy to assemble. Grip feels good. Seems of decent quality and the color is fine. I enjoyed working out with it and am looking forward to doing more. ... show more

  • Durable and comfortable
Style: D.45LB(22.5LB Pair)
Generally good purchase with variety of uses. Weights are easy to switch out. Grip is comfortable. Twist locks hold well, but it's best to check them before you reuse them. Occasionally rolling them will make the twist locks come loose. Easy to assemble. Effective dor working out and easy to use.

Style: A.20LB(10LB Pair)
All-In-1 Home Gym! This versatile kit provides everything you need to stay fit at home. Individually, these pieces would cost hundreds, but with this kit, you get top-notch quality for less. Having used it for over two years, I can attest to its durability, making it perfect for beginners, lighter weight classes, or those focusing on repetition. Plus, its portability is unbeatable - can you think of another high-quality gym set that's this easy to move? ... show more

  • Be careful
Style: D.45LB(22.5LB Pair)
Cool idea but kind of dangerous. Everything screws together and can easily unscrew while using. I found myself having to constantly tighten the plastic connectors.
