Adjustable Dumbbells Buying Guide (2026): What to Check Before You Buy

What to look for

• Pick a weight range that covers your heaviest lifts with room to grow.
• Dial and twist systems are fast; spin-lock plates are slow but cheap.
• Check the length; bulky dumbbells can get in the way on presses.
• Look for a stand or tray so they are easy to pick up.

How much to spend

Typical prices run from £39 to £749. Budget models cover the basics; spending more usually buys fifteen weights in one pair. Only pay for features you will use.

Who should skip what

• Skip the Bowflex SelectTech 552 Adjustable if you need weights above 23.8 kg
• Skip the NÜOBELL Adjustable Dumbbells 2.5–32kg if you only need light weights
• Skip the York Fitness Spinlock Dumbbell Set 20kg if you want fast weight changes
• Skip the Bowflex SelectTech 1090 Adjustable if you want compact dumbbells; these are long

Buying tips

Fitness equipment prices drop in January and on Black Friday. Check shipping weight and return policies, since dumbbells are heavy to send back.
