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.
