Whoever said you couldn't recreate the wheel should have chat with the designer behind these game-changing dumb-bells. One easy turn of the numbered dial on the side allows you to change the weight from 2 to 23kgs. Then all you have to do is grip the ergo handle and lift. Not really suprising that these stylish space savers are Fitness Superstore's best selling dumb-bells, then.

The Sport 9.0s are another set of multiweight dumb-bells, and they offer a similar range of weights – 2.5kg-22.5kg – to the SelectTechs. While they look a lot cheaper, you can buy add-on weight kits for them, which takes the weight up to a staggering 59kgs. If you're looking to go heavy and have limited space, these are definitely what you need.

£899

For your £899 you get 18 dumb-bells ranging from 1kg up to 30kgs. Each one comprises hexagonal rubber weights that won't chip your floor if dropped, and a comfortable ergo handle that distributes weight nicely across the whole dumb-bell.

Another set of traditional bells, these. Where Performance is concerned, there's nothing between these and the other Bodypower weights in this review (they go from 1kg-30kgs, they've got the same grippy ergonomic handles and the weight is well balanced across each dumb-bell), so if you want to go old-school, your choice will largely boil down to which ones you think will look best in your living room.
