Buying tips
- Pick your range first. Most people need a heavier option for presses and squats and a lighter one for curls and raises.
- Check the footprint. Selector-style sets are compact, but measure the space for storage trays.
- Check the seller. On Amazon, confirm whether the item ships from and is sold by Amazon or a third party.
Frequently asked questions
Are selector dumbbells worth it?
They save space and replace several pairs of weights, but they can be slower to adjust than fixed dumbbells and cost more per pound.
How much weight do I need at home?
It depends on your training goals and experience. Many people start with a range that lets them progress over several months.
