Change resistance with one turn
Want to lift 15 lbs? No problem. Just set the dials to 15 and lift. It's just that quick. Want a bigger challenge? Say 40 lbs? Move the dials to 40 and lift.
All you have to do is rotate the dials to the weight you want -- and bam! SelectTech® tumblers automatically fasten to the weight you want to lift.
This innovative design allows us to shrink 30 separate dumbbells down to only 2! That saves you a ton of space - not mention a whole lot of money.
Safety features for maximum protection
Our engineers created a spring-loaded locking pin that prevents the knob of the dumbbell from rotating when you lift your SelectTech® Dumbbells from their base. That means you never have to worry about dropping plates - like you can with old-fashioned dumbbells.
