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 11-55lbs 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.

*Notice: Weight changes must on the tray.


  • Weight Settings: 11lbs, 22lbs, 33lbs, 44lbs, 55lbs Per Hand

Be careful not to drop your dumbbells fall onto a hard surface. Dropping the dumbbell will damage the weight plates and/or the safety locking mechanism, and can cause the weight plates to disengage from the handle or find your dumbbell to get “stuck”.  This can cause serious injury and your warranty will be voided.
