These are bespoke circus-style dumbbells. All are based on a fillable hollow globe construction with the following options/modifications:
The Holle Inch trainers are a simple but effective training tool for lifting circus dumbbells such as the Thomas Inch dumbbell. Standard size is 60mm x 100mm handle with a 25mm loading rod. The loading rod, as can be seen from the image, is welded off-centre in the 60mm handle, depending on how the dumbbell is gripped this can create a turning force to make the dumbbell harder or easier to pick up. Credit must be given to the Holle brothers who first came up with this idea.
