This exercise equipment targets the core muscles (abdominal and lower back extensor, flexor, and oblique muscles) with the simplest mechanism you can think of: a spring! Sandwiched between two sheets of sturdy polypropylene, the Core Slimmer has a spring that will add resistance to any movement of the muscles in your core area, making them stronger and fitter i the process.
