The rundown
Why one pair beats a wall of fixed weights
Seven things that made the difference, from the weight range to the footprint to what it costs against buying seventeen pairs separately.
-
01
17 dumbbells in 1
You replace an entire weight rack
Every pair from 5kg to 40kg lives in one set of SmartBells. Simply turn the smart-dial to select your weight and lift. No clutter.
-
02Reclaim the room
It fits where seventeen pairs never could
Seventeen pairs of dumbbells worth of training in the footprint of one. Set it on its stand in a corner, beside a desk or under a bench, and the whole range is there when you want it.

Best value, per Men's Fitness
The maths beats buying them separately
Buying 17 different pairs of dumbbells can cost well over £1,000 and take a lot of space.

04Progressive overload built in
Micro-jumps keep you progressing
Small, consistent increments across the full range mean you always have the next weight up: the single biggest driver of strength and muscle over time.
-
05
One tool, every muscle
