Dumbbells With Strings Attached

The ReCoil is a workout system where you can train with plain dumbbells or up the act with resistant bands. The bands are cleverly coiled up inside each pod so that you can use them in various stances and have a totally customized workout.
The pods are detachable and can be screwed onto the specially designed dumbbell or curl bar.
I almost forgot, the resistant bands are color-coded and offer different levels of resistance.
Superb!
The ReCoil is a 2011 IDEA Awards entry.
