Say goodbye to 5 dumbbells, and gradually increase your strength using RitFit 1-Sec Adjustable Dumbbell. It gives you convenience while retaining the function of a set of adjustable 11-55lb dumbbells.  

Built in a combination of cast iron, special plastic, and high-density nylon, this dumbbell provides durability, strength, and stability. However, it retains an aesthetically traditional but pleasing iron dumbbell look, giving you comfort when doing exercises like overhead press and goblet squat. If you don’t want to deal with square-shaped blocks, this adjustable dumbbell will become a piece of must-go fitness equipment for your home gym.


With a click-lock handle, you could easily rotate to your desired weight on the indicator, and then you can pull that weight out and do your exercises. This dumbbell is one of the newest options for people looking to save space in their home gym while retaining the functionality of an entire set of dumbbells. Without a doubt, whether you have a gym in your house or your garage, adjustable dumbbells are simply the best option.

Customer Reviews

Unbeatable price for the quality

Purchased two, no problems with either one. Not sure how the handle will hold up against long-term wear, but the weights feel secure and get locked in nicely. Compact, quality design, especially considering the price.

Nice, Jack ! Thanks for sharing your experience :D


I really like the dumbbells and how easily they adjust. The only drawback is that they don’t easily slide back into the “racked” position.

Thanks for your advice, we'll improve our products in the future!

Good service

I was happy that a damaged dumbbell I purchase was replace right away. Very good service.

Thank you for your patience! Customer satisfaction is our priority :)
